How can the concept of density be used to differentiate between a genuine diamond and an imitation diamond

Answers

Explanation: Genuine diamonds and imitation diamonds are different in terms of their strengths.

Strength is directly related to the density of the molecule.

High density means the molecule is hard as there will be no voids and the particles are closer to each other.

Lower density means that the molecule is soft because there will be voids present and the particles will be away from each other.

Genuine diamonds are hard in nature and hence they have high density while imitation diamonds can be broken down easily and hence they have has lower density.

In a longitudinal wave, the _________ is the distance from one compression to the next compression or from one rarefaction to the next rarefaction. WILL MARK BRAINLIEST

Answers

The wavelength in a longitudinal wave is the distance between consecutive compressions or rarefactions. Compressions are analogs to peaks, and rarefactions to troughs of transverse waves, while amplitude refers to the particle displacement from equilibrium.

In a longitudinal wave, the wavelength is the distance from one compression to the next compression or from one rarefaction to the next rarefaction.

Most longitudinal waves consist of areas of higher pressure, known as compressions, where the particles in the medium are closest together, and areas of lower pressure, called rarefactions, where the particles are furthest apart. Therefore, the wavelength of a longitudinal wave can be defined as the distance between two consecutive compressions or two consecutive rarefactions.

The compression in a longitudinal wave is analogous to the peak of a transverse wave, while the rarefaction is analogous to the trough. The amplitude in longitudinal waves represents the extent of displacement of the medium's particles from their equilibrium position, occurring at both compressions and rarefactions.

AnswerGraphene:

Graphene is a semimetal with small overlap between the valence and the conduction bands. It is an allotrope of carbon consisting of a single layer of carbon atoms arranged in a hexagonal lattice (figure 1).It is the basic structural element of many other allotropes of carbon, such as graphite, diamond, charcoal, carbon nanotubes and fullerenes.

Graphene Carbon along metal:

Metal oxides such as TiO2 and ZnO are large-band-gap  semiconductors, and they are photocatalytically active under  UV irradiation. These oxides are capable of interacting with  graphene oxide via carboxylic acid functional groups. Thus, mixing of two suspensions of GO and TiO2 or ZnO  results in the binding of oxide particles to graphene oxide flakes. These particles remain suspended in suspension,  minimizing any aggregation effects.

Graphene Oxide-Metal Nanoparticle Composites

Reduced  graphene oxide serves as a support material to stabilize  metal nanoparticles. For example, the synthesis of silver and  gold nanoparticles stabilized by graphene oxide sheets has  been reported by several research groups.These  composites have also been assembled as ultrathin films using  a layer-by-layer self-assembly technique.30 The procedure to  make these composites consists of mixing of GO and a metal  salt solution (AgNO3, HAuCl4, or H2PtCl6) and adding a dilute  borohydride solution. The chemical reduction process  reduces both GO and metal ions. The RGO acts as a support  to stabilize metal nanoparticles.

Applications:

The resulting G-carbon composite exhibited competitive catalytic activity  and superior methanol tolerance compared to a commercial Pt/C catalyst. Furthermore, it demonstrated significantly higher catalytic efficiency than a Pt/C catalyst.

Why is the collision theory considered to be well-established and highly reliable?

Answers

Collision theory is reliable because it gives a repeatable measure for predicting necessary conditions for reactions, is supported by extensive experimental data, and aligns with scientific principles, only offering limitations when relativistic speeds are involved.

Collision theory is considered well-established and highly reliable because it provides a repeatable measure for predicting the conditions necessary for chemical reactions. These conditions typically include the energy threshold that reacting particles must overcome known as activation energy, and the proper orientation during collisions. This theory is supported by numerous experiments, and no experiment has so far contradicted its postulates. As with the transition from hypothesis to theory in scientific disciplines, collision theory's predictions have been consistently validated by experimental data, making it reliable in the study of reaction rates and mechanisms. It should be noted that the application of collision theory is restricted to non-relativistic speeds, as at relativistic velocities encountered in particle physics, relativistic mechanics would be necessary for correct analysis.

Furthermore, the theory's ability to generalize across various types of collisions, provided we stay in one dimension and minimize external influences such as friction, adds to its dependability. However, in practical applications, especially regarding high-energy collisions between particles like in particle accelerators, adjustments are made to account for the relativistic speeds.

Copper has an atomic number of 29.

B. yes, there is no need to conserve copper.
C. no, we must conserve copper no matter what.
D. yes, the need to conserve copper must be balanced with use

Answers

Answer:

the answer is d

Explanation:

Answer: Option (D) is the correct answer.

Explanation:

When we use an object or substance in excess then it is likely that the substance will run out with time. But at the same time, if we use that substance according to its requirement and try to conserve it as much as we can then we can preserve the substance.

Hence, it is good to avoid wastage of a substance and balance its use according to the need.

Therefore, we can conclude that in the given situation yes, there is a problem with the solution as the need to conserve copper must be balanced with use.

The urine from a diabetic person often has a density less than 1.008 g/mL.

An object will _____ if the weight of the liquid displaced is less than the weight of the object.

Answers

I am not exactly sure the answer that you are looking for, but I will guess on what you might be looking for. If the weight of an object is greater than the weight of the liquid it's being put into, the object will sink. Although, it isn't necessarily just based upon weight, it is more dependent on density to decide if it'll float or sink.

Answer:

It will sink

Explanation:

Hi, this is the result of the Archimedes principle, that states that the push force an object receives from the liquid it is submerged in, is proportional to the volume it displace.

As can be seen in the figure, there are two opposite forces interacting, the weight of the object (P) and the push force (E).

If P is higher than E the object will sinkIf P is lower than E the object will floatIf they are equal the object will be in submerged in equilibrium.

In equations:

[tex]P=m*g[/tex] where g is gravity

[tex]E=\rho_{liq}*V_{liq}*g[/tex]

Also [tex]\rho_{liq}*V_{liq}=m_{liq}[/tex]

So: [tex]\frac{P}{E}=\frac{m*g}{m_{liq}*g}[/tex]

[tex]\frac{P}{E}=\frac{m}{m_{liq}}[/tex]

If m is higher than m_liq, it means that P is higher than E and the object will sink.

why was the mass lost when the reaction was done in the normal setup but stayed the same when it was done in the gas collection setup

Answers

Answer : Law of conservation of massExplanation :

The law of conservation of mass states that in any reaction mass is neither created nor lost it has to remain constant in a system.

In this case, when the reaction setup was done in normal way the mass was  lost in surrounding was not considered nor being calculated; whereas when the reaction was studied in a closed system where the gas was collected after the reaction the mass changes was noted down which helped to prove the point of law of conservation of mass and energy.

One can consider an example of soda can where the carbonated drink contains pressurized carbon dioxide gas. when opened the gas bubbles gets lost into the surroundings and we don't measure the mass changes. Instead if the soda can was opened in such a way where the gas evolved was measured then the mass changed would remain the same.

Final answer:

The discrepancy in mass during a normal setup versus a gas collection setup in a chemical reaction is due to the escape of gaseous products in the former, while the latter contains gases ensuring mass is conserved in accordance with the law of conservation of mass.

Explanation:

The phenomenon you are describing is related to the law of conservation of mass, which states that mass cannot be created or destroyed in a chemical reaction. When you observed a loss of mass in the normal setup, it's likely due to the escape of gas which was not contained. However, in the gas collection setup, no mass is lost because the gases produced are collected and their mass is taken into account, ensuring that the total mass remains the same, which adheres to the conservation of mass.

During chemical reactions, the total mass should always remain constant, as mass is conserved. If there is a difference in mass, as in the loss of -0.1834 g, it usually indicates that a gaseous product has escaped into the atmosphere and was not measured. In contrast, reactions like nuclear fusion and fission create such a vast amount of energy that there may be a measurable decrease in mass since some matter is converted into energy following Einstein's equation, E = mc², though this is not typically observable in chemical reactions.

A sample of NaNO3 was fully decomposed into its elements, and the resulting gas was collected over water at 34°C. If the total pressure of the collected gas was 760 torr, and the vapor pressure of water at 34°C is 40.0 torr, what was the partial pressure of N2 gas in the flask?

Answers

The partial pressure of N2 gas in the flask, after subtracting the vapor pressure of water from the total pressure, is 720 torr.

To determine the partial pressure of N2 gas collected over water, we must subtract the vapor pressure of water from the total pressure of the collected gas according to Dalton's law of partial pressures. Given that the total pressure is 760 torr and the vapor pressure of water at 34°C is 40.0 torr, we can perform the following calculation:

Total pressure = Partial pressure of N2 + Vapor pressure of water .

Therefore, Partial pressure of N2 = Total pressure - Vapor pressure of water

Partial pressure of N2 = 760 torr - 40.0 torr

Partial pressure of N2 = 720 torr

The partial pressure of N2 gas in the flask is 720 torr.

The partial pressure of N2 gas in the flask is 720 torr.

To find the partial pressure of N2 gas, we need to subtract the vapor pressure of water from the total pressure of the collected gas. The total pressure is given as 760 torr, and the vapor pressure of water at 34°C is 40.0 torr.

The partial pressure of a gas in a mixture is calculated using Dalton's Law of Partial Pressures, which states that the total pressure exerted by a mixture of gases is equal to the sum of the partial pressures of each individual gas. Mathematically, this can be expressed as:

[tex]\[ P_{\text{total}} = P_{\text{gas 1}} + P_{\text{gas 2}} + \ldots + P_{\text{gas }n} \][/tex]

where [tex]\( P_{\text{total}} \)[/tex] is the total pressure and [tex]\( P_{\text{gas }i} \)[/tex] is the partial pressure of the i-th gas.

In this case, the total pressure [tex]\( P_{\text{total}} \)[/tex] is 760 torr, and it is composed of the partial pressure of N2 gas [tex]\( P_{\text{N2}} \)[/tex] and the vapor pressure of water [tex]\( P_{\text{H2O}} \)[/tex]:

[tex]\[ P_{\text{total}} = P_{\text{N2}} + P_{\text{H2O}} \][/tex]

We can rearrange this equation to solve for [tex]\( P_{\text{N2}} \)[/tex]:

[tex]\[ P_{\text{N2}} = P_{\text{total}} - P_{\text{H2O}} \][/tex]

Substituting the given values:

[tex]\[ P_{\text{N2}} = 760 \text{ torr} - 40.0 \text{ torr} \] \[ P_{\text{N2}} = 720 \text{ torr} \][/tex]

Therefore, the partial pressure of N2 gas in the flask is 720 torr.

use Hess's law to calculate ΔH for the following reaction:
N2O(g)+NO2(g)→3NO(g)

Answers

Answer is: enthalpy is 155.65 kJ.

Reaction 1: N₂(g) + O₂(g) → 2NO(g); ΔrH₁ = 180.7 kJ.

Reaction 2: 2NO(g) + O₂(g) → 2NO₂(g); ΔrH₂ = -113.1 kJ.

Reaction 3: 2N₂O → 2N₂(g) + O₂(g); ∆rH₃ = -163.2 kJ.

Reaction 4: N₂O(g) + NO₂(g) → 3NO(g); ΔrH₄ = ?.

Using Hess's law reaction number 4 is sum of reaction number 1 and half of reaction number 3 minus half of the reaction number 2.

ΔrH₄ = ΔrH₁ + 1/2ΔrH₃ - 1/2ΔrH₂.

ΔrH₄ = 180.7 kJ + 1/2 · (-163.2 kJ) - 1/2 · (-113.1 kJ).

ΔrH₄ = 155.65 kJ.

a rough guide to fluid requirements based on body weight is 100mL/kg for the first 10kg of body weight, 50mL/kg for the next 10kg, and 20mL/kg for weight over 20kg. What volume of fluid per day is needed by a 55kg woman? give answer to 2 significant figures

Answers

Given, weight of the woman = 55 kg

For the first 10 kg, fluid required is 100 mL/kg

So for the first 10 kg volume of fluid required is 100 ml/kg  x 10 kg = 1000 ml = 1 L

For the second 10 kg, fluid required is 50 mL/kg

So for the second 10 kg volume of fluid required is 50 ml/kg x 10 kg = 500 ml = 0.5 L

For the remaining (55 kg - 20 kg ) or 35 kg, fluid required is 20mL/kg

Now for the the remaining 35 kg  volume of fluid required is 20 ml/kg x 35 kg = 700 ml = 0.7 L

The total volume of fluid per day required by a 55 kg woman = 1L + 0.5L + 0.7L = 2.2 L

The volume of fluid per day needed by a 55kg woman, based on the given guide to fluid requirements, is 1000mL for the first 10kg, 500mL for the next 10kg, and 700mL for the remaining weight, totaling 2200mL or 2.2 liters per day when rounded to two significant figures.

To calculate the volume of fluid per day needed by a 55kg woman based on the rough guide to fluid requirements, we use the following method:

For the first 10kg of body weight: 100mL/kg.

For the next 10kg of body weight: 50mL/kg.

For the remaining weight over 20kg: 20mL/kg.

So for a 55kg woman:

For the first 10kg: 10kg x 100mL/kg = 1000mL

For the next 10kg: 10kg x 50mL/kg = 500mL

For the remaining 35kg: 35kg x 20mL/kg = 700mL

Therefore, the total fluid requirement is 1000mL + 500mL + 700mL = 2200mL, which rounded to two significant figures is 2200mL or 2.2 liters per day.

Final answer:

To find the mass of fluorine in the sample, subtract the mass of chromium from the total mass of the sample. In a 36.01 g sample of CrF₃ with 18.83 g of Cr, there are 17.18 grams of fluorine.

Explanation:

The student asks how many grams of fluorine (F) are in a 36.01 g sample of chromium (III) fluoride (CrF₃) if there are 18.83 g of chromium (Cr) in the sample. To answer this, we conduct a mass difference calculation.

First, we subtract the mass of chromium (Cr) from the total mass of the sample to determine the mass of fluorine present:

Total mass of CrF₃ sample = 36.01 gMass of Cr in the sample = 18.83 gMass of F in the sample = Total mass of CrF₃ sample - Mass of CrMass of F in the sample = 36.01 g - 18.83 g = 17.18 g

Therefore, there are 17.18 grams of fluorine in the 36.01 g sample of CrF₃.
