Activated carbon filters use chemical means to seperate impurities from air:

Chemical reactions occurs when compounds are formed. Activated carbon filters are made up of activated carbons in which impurities have been removed and the pores of the carbon structure have become widened. This leaves the carbon with much surface area for chemical reaction to occur between impurities and the carbon in form of chemical adsorption. One important thing to note is that, in chemical change, it is difficult to resolve the reactants after the product is formed. In physical change, simple seperation techniques are used to seperate the reactants out.

Final answer:

A cylinder is a 3-dimensional geometric shape with two parallel circular bases and a curved surface. It has applications across disciplines, including biology and physics, where its volume calculation (V = A*h) is crucial, and its shape influences resistance in electric circuits and the properties of capacitors and sound.

Explanation:

The definition of a cylinder in mathematics refers to a 3-dimensional geometric shape with two parallel circular bases connected by a curved surface. This surface is perpendicular to the bases and extends the same distance from every point on one base to the corresponding point on the other base. Cylinders can be found in various applications, from everyday objects like pipes and cans to biological structures and fluid dynamics.

In biology, cylinders are significant structures for mobility in organisms. For example, stolons in plants and rhizomorphs in fungi have cylindrical shapes that allow them to spread and cover territory effectively. Similarly, in physics, the concept of a cylinder is used to understand resistance in electric circuits and fluid mechanics. The volume of a cylinder is calculated by multiplying its cross-sectional area A by its height (V = A*h), which is a crucial factor in determining its capacity or the amount of substance it can hold.

In addition, when discussing capacitors or sound in physics, a cylindrical shape is a fundamental part of the structure affecting their properties. These examples demonstrate the importance of understanding cylindrical geometry in both theoretical and practical applications.

A solid changes to a liquid when heat is added because the energy causes particles to vibrate more vigorously, increasing the spacing between them and allowing them to move more freely, thus overcoming the forces holding them in a solid state. Option C is correct .[The spacing between particles increases]

When heat is added to a solid, it causes the particles (such as atoms or molecules) in the solid to gain energy. This increase in energy causes the particles to vibrate more vigorously, which weakens the forces that hold them together in a fixed position. As a result, the particles can start to move around more freely. This is why the spacing between particles increases, leading to a state change from solid to liquid. This transition from solid to liquid is referred to as melting.

During this phase change, the temperature of the substance does not increase; instead, the added energy is used to overcome the intermolecular forces and change the state of the substance. Once enough energy has been absorbed to weaken these forces sufficiently, the solid becomes a liquid.

Answer:mass and volume

Explanation: as i know you should divide mass and volume for obtain density

Answer : The correct option is, Mass and volume.

Explanation :

Density : It is defined as the mass of a substance contained per unit volume.

The unit of mass is gram (g) and the unit of volume is milliliter (ml). So, the unit of density is g/ml.

Formula used :

[tex]Density=\frac{Mass}{Volume}[/tex]

For example : If mass of object is 550 grams  and volume of water displaced 25 ml. Calculate the density of an object.

By using formula, we get:

[tex]Density=\frac{550g}{25ml}=22g/ml[/tex]

Thus, density of the object will be 22 g/ml

Hence, the mass and volume measurements are needed in order to calculate the density of a given object.

A car travels 66 kilometers in 3 hours 22 km/h is its speed. The speed of an object, also known as v in kinematics.

The speed of an object, also known as v in kinematics, is the size of the change in that object's position over a period of time or the size of the change in that object's position over a given period of time, making it a scalar quantity. The total amount of distance travelled by an object in a time interval is divided by the length of the interval to determine its average speed.

As the length of the time period approaches 0, the speed at that moment is the highest point of the average speed. Velocity and speed are not the same thing. The parameters of speed are time divided by distance. The metre every second (m/s), the SI measure of speed, is the most widely used unit measuring speed.

Speed = distance/time

Speed = 66 km / 3 h

Speed = 22 km/h

a) 45 g of water                      

b) 200 g of aluminum             Cp = 0.905 J/cal°C

a) Water

Q = mCpΔT

Q = (45)(1)(85 - 22) = 45(63) = 2835 cal

Answer:

122.04g

Explanation:

Cs is Caesium

Mass of Sn, tin = 109g.

Solution

we must first find the number of moles of the Sn from the given mass:

       number of moles = [tex]\frac{mass}{molar mass}[/tex]

molar mass of Sn = 118.7g/mol

      number of moles =  [tex]\frac{109}{118.7}[/tex] = 0.918moles

Now since the number of moles of the Sn is the sameas that of Cs, we can find the mass of Cs that will equal that.

Mass of Cs = number of moles x molar mass of Cs = 0.918 x 132.9 = 122.04g

To find the mass of cesium with the same number of moles as a 109-gram sample of tin, we calculate the moles of tin and then use the molar mass of cesium to find that it would be approximately 125.766 grams.

The student's question is asking for the mass of cesium (Cs) in grams when it contains the same number of moles as a 109-gram sample of tin (Sn). To find the answer, we first calculate the number of moles in the 109-gram sample of tin using the molar mass of tin (118.7 g/mol), which gives us approximately 0.918 moles.

Since we are looking for the same amount of moles in cesium, and knowing that one mole of cesium has a mass of 137 grams according to the given information, the mass of cesium would be approximately 125.766 grams (0.918 moles × 137 g/mol = 125.766 g).

An extensive property is a property that depends on the amount of matter in a sample. Mass and volume are examples of extensive properties. An intensive property is a property of matter that depends only on the type of matter in a sample and not on the amount.

HOPE THIS HELPED!!!!!!!!!!!!!!XDDDDDDDDD

Final answer:

An extensive property depends on the amount of matter in a sample, examples being mass and volume. Intensive properties such as temperature do not vary with the quantity of matter. The differentiation between these property types is essential for accurately describing and measuring substances in chemistry.

Explanation:

A property that depends on the amount of matter in a sample is called an extensive property. Examples of extensive properties are mass and volume. For instance, a gallon of milk has a greater mass and volume than a cup of milk, illustrating that the value of an extensive property increases with the amount of matter. In contrast, an intensive property does not depend on the amount of matter; temperature is an example of this, where the temperature of small or large quantities of a substance at thermal equilibrium will be the same.

Understanding the difference between extensive and intensive properties is crucial for characterizing substances and engaging in scientific measurements. The amount of heat is an extensive property because it depends on the matter's quantity, whereas temperature is an intensive property as it remains consistent regardless of the sample size. A hot cooking oil drop and a pot of hot oil could have the same temperature, an intensive property, yet the pot contains more heat, showing an extensive property.

Final answer:

The density of an 8cm³ block of brown sugar with a mass of 12.9g is calculated by dividing mass by volume, resulting in a density of 1.6125 g/cm³.

Explanation:

To calculate the density of the brown sugar, we need to use the formula density = mass/volume. The student measured a mass of 12.9g for an 8 cm³ block of brown sugar. To find the density, we divide the mass by the volume of the sugar block.

The calculation is as follows:

Density = Mass / Volume
Density = 12.9g / 8 cm³
Density = 1.6125 g/cm³

Hence, the density of the brown sugar is 1.6125 g/cm³.

Approximately 7.80 g of this multi-nutrient fertilizer should be applied to provide 2.90 g of nitrogen to a plant, assuming the nitrogen is 100% available to the plants.

To calculate the amount of fertilizer needed to provide 2.90 g of nitrogen, we need to know the nitrogen content in each component of the fertilizer. The nitrogen content of the compounds CH4N2O (urea), KNO3, and (NH4)2HPO4 is approximately 46.6%, 13.9%, and 21.2% respectively. Therefore, the total percentage of nitrogen in the fertilizer is ((0.548 * 46.6) + (0.263 * 13.9) + (0.141 * 21.2))/(0.548 + 0.263 + 0.141) = 37.2%.

To provide 2.90 g of nitrogen, we need to apply: 2.90 g / 0.372 = 7.80 g of fertilizer. This calculation assumes that the nitrogen in the fertilizer is 100% available to the plants, which may not be the case because plants require certain biochemical processes like nitrogen fixation to make nitrogen bioavailable.

C2H4O2 + NaHCO3 - NaC2H302 + H2O + CO2

Explanation:

To solve this you have to check the number of elements in both sides of the equation.

Answer:

Choice A: [tex]\rm 1\; C_2H_4 O_2 + 1\;NaHCO_3 \to 1\;NaC_2H_3O_2 + 1\;H_2O + 1\;CO_2[/tex].

Explanation:

Indeed it is possible to balance this equation by the conservation of atoms in a chemical reaction. However, knowing what's actually going on in this process will likely make this problem easier to solve.

Vinegar contains acetic acid [tex]\rm C_2H_4 O_2[/tex]. Acetic acid is a monoprotic acid. In other words, each [tex]\rm C_2H_4 O_2[/tex] can dissociate to produce up to one hydrogen ion [tex]\rm H^{+}[/tex]. That is:

[tex]\rm C_2H_4 O_2 \rightleftharpoons {C_2H_3 O_2}^{-} + H^{+}[/tex].

Baking soda is a common name for sodium bicarbonate [tex]\rm NaHCO_3[/tex]. Each formula unit of [tex]\rm NaHCO_3[/tex] contains one bicarbonate ion: [tex]\rm {HCO_3}^{-}[/tex]. Each bicarbonate ion will consume one hydrogen ion to produce water and carbon dioxide:

[tex]\rm {HCO_3}^{-} + H^{+} \to H_2O + CO_2[/tex].

For this chemical equation to balance, the number of hydrogen ions that [tex]\rm C_2H_4 O_2[/tex] supplies shall be the same as the number of these ions that [tex]\rm NaHCO_3[/tex] consumes. Each unit of [tex]\rm C_2H_4 O_2[/tex] supplies one unit of hydrogen ions while each unit of [tex]\rm NaHCO_3[/tex] consumes one unit of hydrogen ions. Reacting the two at a one-to-one ratio will make sure that this reaction neither run short of hydrogen ions or produce more hydrogen ions than it need.

Hence the coefficient in front of [tex]\rm C_2H_4 O_2[/tex] and [tex]\rm NaHCO_3[/tex] shall be the same. Let their coefficients be one.

[tex]\rm 1\; C_2H_4 O_2 + 1\;NaHCO_3 \to ?\;NaC_2H_3O_2 + ?\;H_2O + ?\;CO_2[/tex].

Now, balance this equation with reference to the number of atoms:

[tex]\rm 1\; C_2H_4 O_2 + 1\;NaHCO_3 \to 1\;NaC_2H_3O_2 + 1\;H_2O + 1\;CO_2[/tex].

Answer: Option (A) is the correct answer.

Explanation:

It is known that kinetic energy is the energy obtained by an object due to its motion.

And, when we increase the temperature of a substance then there will occur an increase in the kinetic energy of its molecules.

Also,      K.E = [tex]\frac{3}{2}kT[/tex]

So, kinetic energy is directly proportional to the temperature. As a result, on increasing the temperature more number of collisions will take place between the molecules.

Therefore, we can conclude that amount of kinetic energy in the substance’s particles changes its states of matter.

A substance changes its state of matter primarily due to changes in the amount of kinetic energy in its particles, often induced by temperature changes.

A change in a substance's state of matter is primarily due to the change in the amount of kinetic energy in the substance's particles, which is often triggered by changes in temperature (Option A). Kinetic energy is the energy a particle possesses due to its motion. An increase in kinetic energy (which could be due to an increase in temperature) typically causes the substance to go from a solid to a liquid (melting) or a liquid to a gas (evaporation). Conversely, a decrease in kinetic energy (for example during cooling) can cause a substance to go from a gas to a liquid (condensation) or a liquid to a solid (freezing).

Answer:

One single coordinate covalent bond and one double covalent bond between the oxygen atoms, not in the expected triangular but in 1 bond structure.

Explanation:

O³ is also called ozone, and has three atoms in each molecule which makes it an allotropic form of oxygen.

Compared to oxygen, ozone is much more chemically active.

⇒The structure of ozone has 3 oxygen atoms, but due to steric hindrance, they can't  form the expected triangular structure, with each O atom.

⇒Instead each Oxygen forms only 1 bond, with the remaining negative charge being spread throughout the molecule, with one single coordinate covalent bond and one double covalent bond.

⇒The two O-O that share the double covalent bond are nonpolar as there is no electronegativity between  atoms of the same element (they share the same number of electrons, so there is no difference).

⇒ However, the distribution of the electrons along the 3 oxygen atoms is uneven, because the central atom must share electrons with the two atoms at both sides. The outer atoms only share electrons with the central atom.

So we can say that the central atom is more deprived of electrons than the 2 other oxygen atoms.

In terms of geometry,the molecule is bent, which is the result of this sharing of electrons and thus results in a dipole force across the ozone molecule.

Filtration followed by evaporation:

To separate the mixture of sand and sugar, it is best to use the separation technique of filtration then evaporation.

Pour the water into the mixture. The sugar will dissolve with time in the water. Sand is made up of quartz and does not dissolve in water.

After the dissolution, filter the solution to separate the sand using a filter paper.

Dry the sand thereafter then proceed to evaporate the sugar with water solution. Evaporation will turn water into vapor and the sugar crystals will be left behind.

To separate sugar from sand in a water mixture, filtration followed by evaporation is the most effective method. Sand is retained on the filter paper, while the sugar dissolves in the water and can be retrieved through evaporation.

To separate sugar from sand in a solution with water, we can use the concept that sugar is soluble in water whereas sand is not. The separation can be achieved by a process called filtration. First, we stir the mixture to ensure that all the sugar dissolves in the water. Then, we pour the mixture through a filter paper. The sand particles will be trapped by the filter paper, while the sugar-laden water will pass through. After collecting the filtrate (the sugar-water solution), we can recover the sugar by evaporating the water, leaving the sugar behind.

Additionally, we can consider the density difference between sugar and sand as a factor irrelevant to this method of separation but interesting to note for other purposes such as differentiating substances in a pile, as with the take-home experiment with sugar and salt. Also, while this experiment doesn't involve visiting virtual labs, such labs can be useful for understanding the dissolution behaviors of substances like sugar and salt in water.

An object with a lot of mass always has a lot of matter. This doesn't mean it necessarily has a large volume or high density, and it can be accurately measured.

The statement that is always true of an object with a lot of mass is that it contains a lot of matter. Put simply, the mass of an object is a measure of how much matter the object contains. It's derived from the quantity of atoms and molecules within the object. Mass is different from volume, which is the amount of space an object occupies, and density, which is the ratio between mass and volume. Therefore, it's not necessarily true that an object with a lot of mass will also have a large volume or high density. The mass of an object can always be measured precisely, given the right tools. Therefore, it's incorrect to say an object with a lot of mass cannot be accurately measured.

Answer:

One can of cola contain 0.16 kcal of carbohydrates.

Explanation:

Given data:

mass of cola can = 40 g

kilocalories of carbohydrates = ?

Solution:

we know that there are 4 cal of carbohydrates per gram.

40 g × 4 cal/g = 160 cal

Now we will convert calories into kilocalories. There are 1000 calories in one kilocalories so,

160/1000 = 0.16 kcal

so, one can of cola contain 0.16 kcal of carbohydrates.

Final answer:

To calculate the kilocalories in a can of cola with 40 grams of carbohydrate, multiply the amount of carbohydrate by 4 kilocalories per gram. This results in 160 kilocalories.

Explanation:

The number of kilocalories in one can of cola can be calculated knowing that carbohydrates provide 4 kilocalories of energy per gram. Given that the cola has 40 grams of carbohydrate and no fat or protein, we can simply multiply the amount of carbohydrate by the energy it provides.

So, 40 grams of carbohydrate * 4 kilocalories/gram = 160 kilocalories.

This means that one can of cola, with its 40 grams of carbohydrates and no contribution from fat or protein to its energy content, provides a total of 160 kilocalories of energy.

The prone position in medical contexts involves a patient lying face-down and can aid in breathing and medical procedures, offering benefits like improved air intake for artificial respiration.

Prone position is when a person is lying face-down. In medical settings, patients might need to be in a prone position for reasons such as aiding in breathing or allowing for specific medical procedures.

One major advantage of the prone position is that it allows for better air intake into the lungs, which can be crucial in scenarios like artificial respiration.

Artificial respiration, such as in cases of drowning, can benefit from the prone position as it facilitates the removal of mucus and water from the airways.
