Explanation:

Final answer:

The second law of thermodynamics states that entropy either increases or remains constant in any spontaneous process. Heat transfers energy from higher to lower temperature objects, not the other way around.

Explanation:

The second law of thermodynamics states that the total entropy of a system either increases or remains constant in any spontaneous process; it never decreases. An important implication of this law is that heat transfers energy spontaneously from higher- to lower-temperature objects, but never spontaneously in the reverse direction. This is because entropy increases for heat transfer of energy from hot to cold. The decrease in entropy of the hot object is therefore less than the increase in entropy of the cold object, producing an overall increase in entropy for the system.

The velocity of the airplane flying at 635 km/hour at an altitude of 35,000m is 635km/hr.

Velocity is a vector quantity that denotes the rate of change of position with respect to time, combining speed with a directional component.

According to this question, an airplane is flying at 635 km per hour at an altitude of 35,000m. The velocity of the airplane is already in the question and it is 635km/hr.

The velocity of a moving object is measured in metres/seconds, kilometer/hour etc.

Decreasing the temperature of orange juice increases its pH level because the solubility of carbon dioxide (CO2) in the juice decreases, leading to less carbonic acid formation and therefore a higher pH, meaning the juice becomes less acidic.

The pH of a solution is a measure of its acidity or basicity. In the case of orange juice, the main source of its acidity is the various organic acids present, such as citric acid. However, carbon dioxide (CO2) dissolved in the juice also contributes to its acidity through the formation of carbonic acid (H2CO3). Temperature plays a role in the solubility of gases in liquids; as temperature decreases, the solubility of gases increases. Conversely, when the temperature is increased, the solubility of gases like CO2 decreases, which means less CO2 is dissolved in the juice, leading to less carbonic acid formation, and thus a reduction in the overall acidity level. The pH level, therefore, increases with a decrease in temperature.

Answer:

why molecules have different shapes lol

Explanation:

The acid and base that formed the salt [tex]Ca_3(PO_4)_2[/tex]  would be phosphoric acid ([tex]H _3PO _4[/tex]) and calcium hydroxide ([tex]Ca(OH)_2[/tex] respectively.

Salts are usually formed from neutralization reactions. That is, reactions involving acids and bases to produce salts and water.

In order to form [tex]Ca_3(PO_4)_2[/tex]  from an acid and a base, such an acid must be phosphoric in nature while the base must be calcium-based.

Thus:

          [tex]Ca(OH)_2 + H_3PO_4 --- > Ca_3(PO_4)_2 + H_2O[/tex]

Answer:

c) 2 mol of Kl in 500. g of water

Explanation:

Colligative properties such as melting and boiling points and osmotic pressure all depend on the amount of solute present. The more the concentration of solute present, the greater the degree of display of colligative properties by a solution

Considering the options given, 2 mol of Kl in 500. g of water has the highest concentration and is expected to freeze at the lowest temperature.

Answer:

1. Heat flows faster through a thin material.

2. Heat flows through a large surface area.

3. Heat flows faster for a large change in temperature.

Explanation:

Thinking process:

Newton's law of cooling or heat transfer is given by the following equation:

[tex]Q= kA\delta T[/tex]

Where Q = Heat change (J)

A = area of hear transfer (m²)

[tex]\fdelta[/tex][tex]\delta T[/tex] = Change in temperature.

However, for a temperature difference across the wall having a thickness "x"and  a constant surface area A, we get,

[tex]Q= k.A\frac{T_{1} - T_{2} }{x}[/tex]

Where x = thickness of the material

As we can see, increasing the thickness, x, decreases the heat flux

Increasing the area, A increases the heat flux

A big temperature increase, ΔT results in a large heat transfer.

Final answer:

Heat transfers more quickly through a thin material and with a larger contact surface area. Moreover, a greater temperature difference accelerates the rate of heat flow.

Explanation:

Heat conductivity is greatly influenced by three key factors:

In summary, the rate of heat transfer through a material is directly proportional to the temperature difference and surface area, while inversely proportional to the material's thickness.

Answer: The mass of zinc chloride produced will be 12.402 grams.

Explanation:

To calculate the number of moles, we use the equation:

[tex]\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}[/tex]  .....(1)

Given mass of zinc = 6 g

Molar mass of zinc = 65.38 g/mol

Putting values in above equation, we get:

[tex]\text{Moles of zinc}=\frac{6g}{65.38g/mol}=0.091mol[/tex]

For the reaction of zinc and hydrochloric acid, the chemical equation follows:

[tex]Zn(s)+2HCl(aq.)\rightarrow ZnCl_2(s)+H_2(g)[/tex]

Hydrochloric acid is given in excess, so it is considered as an excess reagent. Zinc is considered as a limiting reagent because it limits the formation of product.

By Stoichiometry of the reaction:

1 mole of zinc metal produces 1 mole of zinc chloride.

So, 0.091 moles of zinc metal will produce = [tex]\frac{1}{1}\times 0.091=0.091moles[/tex] of zinc chloride.

Now, calculating the mass of zinc chloride produced, we use equation 1.

Moles of zinc chloride = 0.091 moles

Molar mass of zinc chloride = 136.286 g/mol

Putting values in equation 1, we get:

[tex]0.091=\frac{\text{Mass of zinc chloride}}{136.286g/mol}\\\\\text{Mass of zinc chloride}=12.402g[/tex]

Hence, the mass of zinc chloride produced will be 12.402 grams.

The answerto your question is Xylem

Answer: limestone

Explanation:

Final answer:

The 1600 g iron brick would release 93,568 joules of heat energy as it cools from 155°C to 25°C.

Explanation:

The heat energy released by a 1600 g brick of iron as it cools from 155°C to 25°C can be calculated using the specific heat capacity of iron and the formula Q = mcΔT, where Q is the heat energy in joules, m is the mass in grams, c is the specific heat capacity in J/g°C (for iron, c = 0.449 J/g°C), and ΔT is the change in temperature.

To find out how much heat energy is released, we calculate:

Mass (m) = 1600 g

Change in temperature (ΔT) = 155°C - 25°C = 130°C

Specific heat capacity (c) = 0.449 J/g°C

Substitute these values into the formula:

Q = 1600 g × 0.449 J/g°C × 130°C

Q = 93568 J

Therefore, the 1600 g brick of iron would release 93,568 joules of heat energy as it cools to 25°C.

Answer: The molarity of solution is 2.7 M

Explanation:

To calculate the molarity of solution, we use the equation:

[tex]\text{Molarity of the solution}=\frac{\text{Mass of solute}\times 1000}{\text{Molar mass of solute}\times \text{Volume of solution (in mL)}}[/tex]

We are given:

Mass of solute (ammonium nitrate) = 68.2 g

Molar mass of ammonium nitrate = 80 g/mol

Volume of solution = 315 mL

Putting values in above equation, we get:

[tex]\text{Molarity of solution}=\frac{68.2g\times 1000}{80g/mol\times 315mL}\\\\\text{Molarity of solution}=2.7M[/tex]

Hence, the molarity of solution is 2.7 M

Answer:-

If an element has 3 or more valence electrons then the element belongs to p block of the periodic table. For p block elements the group number is found out by adding the number of electrons in valence shell + 10.

The reason for this is because in the middle of the periodic table there are the d block elements ranging from group 3 to group 12 a total of 10 groups in between elements having 2 valence electrons and 3 valence electrons

The dissolution of LiCl in water and the temperature rise from 18.2°C to 22.9°C suggests an exothermic dissolution process in thermochemistry, related to high school chemistry.

The question deals with the dissolution of Lithium Chloride (LiCl) in water and the resulting temperature change, which is a concept in thermochemistry. When a solute dissolves in a solvent, it can either absorb heat from the water, resulting in a temperature decrease (endothermic) or release heat to the water, causing the temperature to increase (exothermic). The observed temperature increase from 18.2°C to 22.9°C in this scenario indicates that the dissolution of LiCl in water is an exothermic process. To calculate the heat involved in the process, one would need to know the specific heat capacity of the solution, which is often assumed to be similar to that of pure water (4.18 J/g°C) if the solution is not very concentrated.
