Consider this graph showing temperature over time. What would happen in the situation? The temperature decreases from 25° to 15°C, the material ____ heat and its kinetic energy ____ as the material, freezes to become a solid.


Answers

Answer:

One of the major effects of heat transfer is temperature change: heating increases the temperature while cooling decreases it. We assume that there is no phase change and that no work is done on or by the system. Experiments show that the transferred heat depends on three factors—the change in temperature, the mass of the system, and the substance and phase of the substance.

A chemist prepares a solution of barium acetate BaCH3CO22 by weighing out 52.9g of barium acetate into a 100.mL volumetric flask and filling the flask to the mark with water. Calculate the concentration in /gL of the chemist's barium acetate solution. Round your answer to 3 significant digits.

Answers

Answer:

529g/L

Explanation:

The concentration in chemistry is defined as the amount of solute in a determined amount of solution. The concentration in g/L means the amount of grams of solute (In this case, barium acetate), per liter of solution.

To solve this problem we need to find grams of solute (52.9g, already given) and the volume in liters (Converting 100mL to liters):

Volume:

100mL * (1L / 1000mL) = 0.100L

And concentration in g/L is:

52.9g / 0.100L =

529g/L

what is the empirical formula of A compound is found to contain 39.12 % carbon, 8.772 % hydrogen, and 52.11 % oxygen by mass.

Answers

Answer:

C₃H₈O₃

Explanation:

Let's assume we have 100 g of said compound. Then we would have:

39.12 g of C8.772 g of H52.11 g of O

Now we convert those masses into moles, using their respective atomic weights:

C ⇒ 39.12 g ÷ 12 g/mol = 3.26 mol CH ⇒ 8.722 g ÷ 1 g/mol = 8.722 mol HO ⇒ 52.11 g ÷ 16 g/mol = 3.26 mol O

Then we divide those moles by the smallest number among them:

C ⇒ 3.26 mol C / 3.26 = 1H ⇒ 8.722 mol H / 3.26 = 2.68O ⇒ 3.26 mol O / 3.26 = 1

Finally we multiply those numbers by 3, so as to convert the 2.68 of H into an integer:

C ⇒ 1 * 3 = 3H ⇒ 2.68 * 3 = 8O ⇒ 1 * 3 = 3

Thus the empirical formula is C₃H₈O₃


How do you know whether or not a chemical
reaction equation follows the law of
conservation of mass?

Answers

Answer:

- Because it has or not the same number of atoms at each side.

- Because the mass of reactants and product is or not the same after the reaction.

Explanation:

Hello!

In this case, since the law of conservation of mass states that matter cannot be created nor destroyed; when we see a chemical reaction, we need to make sure that the amount of atoms is the same at both reactants and products; for instance the formation of water requires four hydrogen atoms and two oxygen atoms at both reactants and products sides as shown below:

[tex]2H_2+O_2\rightarrow 2H_2O[/tex]

Another way is by proving that the total mass of products equals the total mass of reactants once the reaction has gone to completion.

g Suppose a 49. L reaction vessel is filled with 1.5 mol of NO. What can you say about the composition of the mixture in the vessel at equilibrium

Answers

The question is incomplete, the complete question is:

At a certain temperature, the equilibrium constant [tex]K_{eq}[/tex] for the following reaction is 0.74:

[tex]NO_3(g)+NO(g)\rightleftharpoons 2NO_2(g)[/tex]

Suppose a 49.0 L reaction vessel is filled with 1.5 mol of [tex]NO_3[/tex] and 1.5 mol of NO. What can you say about the composition of the mixture in the vessel at equilibrium?  

A. There will be very little [tex]NO_3[/tex] and NO.

B. There will be very little [tex]NO_2[/tex]

C. Neither of the above is true.

Answer: The correct option is B. there will be very little [tex]NO_2[/tex]

Explanation:

We are given:

Initial moles of [tex]NO_3[/tex] = 1.5 moles

Initial moles of NO = 1.5 moles

Volume of vessel = 49 L

As, moles of reactants and moles of products are equal, the volume term will not appear in the equilibrium constant expression.

Equilibrium constant for the reaction = 0.74

For the given chemical equation:

                                  [tex]NO_3(g)+NO(g)\rightleftharpoons 2NO_2(g)[/tex]

Initial:                            1.5           1.5             -

At eqllm:                     1.5-x        1.5-x            2x

The expression of equilibrium constant for the above reaction:

[tex]K_{eq}=\frac{[NO_2]^2}{[NO_3]\times [NO]}[/tex]

Putting values in above equation, we get:

[tex]0.74=\frac{(2x)^2}{(1.5-x)(1.5-x)}\\\\x=-1.13, 0.451[/tex]

Neglecting the negative value of equilibrium constant because concentration cannot be negative

Equilibrium concentration of [tex]NO_3[/tex] = (1.5 - x) = (1.5 - 0.451) = 1.049 moles

Equilibrium concentration of NO = (1.5 - x) = (1.5 - 0.451) = 1.049 moles

Equilibrium concentration of [tex]NO_2[/tex] = 2x = [tex](2\times 0.451)=0.902mol[/tex]

There are 3 possibilities:

If [tex]K_{eq}<1[/tex], the reaction is reactant favoredIf [tex]K_{eq}>1[/tex], the reaction is product favored.If [tex]K_{eq}=1[/tex], the reaction is in equilibrium.

Here, the value of [tex]K_{eq}=0.74[/tex], which is less than 1, therefore the reaction is reactant favored and we can say that there will be very little [tex]NO_2[/tex].

Hence, the correct option is B. there will be very little [tex]NO_2[/tex]

If 8.50 g of phosphorus reacts with hydrogen gas at 2.00 atm in a 10.0-L container at 298 K, calculate the moles of PH3 produced as well as the total number of moles of gas present at the conclusion of the reaction.

Answers

Answer:

The moles of PH₃ produced are 0.2742 and the total number of moles of gas present at the end of the reaction is 0.6809.

Explanation:

Phosphorus reacts with H₂ according to the balanced equation:

P₄ (s) + 6 H₂ (g) ⇒ 4 PH₃ (g)

By stoichiometry of the reaction (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of each compound participate in the reaction:

P₄: 1 moleH₂: 6 molesPH₃:4 moles

Being the molar mass of the compounds:

P₄: 124 g/moleH₂: 2 g/molePH₃: 34 g/mole

The following mass amounts of each compound participate in the reaction:

P₄: 1 mole* 124 g/mole= 124 gH₂: 6 mole* 2 g/mole= 12 gPH₃: 4 moles* 34 g/mole= 136 g

An ideal gas is characterized by three state variables: absolute pressure (P), volume (V), and absolute temperature (T). The relationship between them constitutes the ideal gas law, an equation that relates the three variables if the amount of substance, number of moles n, remains constant and where R is the molar constant of the gases:

P * V = n * R * T

In this case you know:

P= 2 atmV= 10 Ln= ?R= 0.082 [tex]\frac{atm*L}{mol*K}[/tex]T= 298 K

Replacing:

2 atm*10 L= n*0.082 [tex]\frac{atm*L}{mol*K}[/tex] *298 K

and solving you get:

[tex]n=\frac{2 atm*10 L}{0.082\frac{atm*L}{mol*K}*298 K }[/tex]

n=0.818 moles

The limiting reagent is one that is consumed first in its entirety, determining the amount of product in the reaction. When the limiting reagent is finished, the chemical reaction will stop.

To determine the limiting reagent, you can use a simple rule of three as follows: if 6 moles of H₂ react with 124 g of P₄, 0.818 moles of H₂ with how much mass of P₄ will it react?

[tex]mass of P_{4}=\frac{0.818 moles of H_{2}*124 grams of P_{4}}{6 moles of H_{2}}[/tex]

mass of P₄= 16.90 grams

But 16.90 grams of P₄ are not available, 8.50 grams are available. Since you have less mass than you need to react with 0.818 moles of H₂, phosphorus P₄ will be the limiting reagent.

Then you can apply the following rules of three:

If 124 grams of P₄ produce 4 moles of PH₃, 8.50 grams of P₄, how many moles do they produce?

[tex]moles of PH_{3} =\frac{8.5 grams of P_{4}*4 moles of PH_{3} }{124grams of P_{4}}[/tex]

moles of PH₃=0.2742

If 124 grams of P₄ react with 6 moles of H₂, 8.50 grams of P₄ with how many moles of H₂ do they react?

[tex]moles of H_{2} =\frac{8.5 grams of P_{4}*6 moles of H_{2} }{124grams of P_{4}}[/tex]

moles of H₂= 0.4113

If you have 0.818 moles of H₂, the number of moles of gas H₂ present at the end of the reaction is calculated as:

0.818 - 0.4113= 0.4067

Then the total number of moles of gas present at the end of the reaction will be the sum of the moles of PH₃ gas and H₂ gas that did not react:

0.2742 + 0.4067= 0.6809

Finally, the moles of PH₃ produced are 0.2742 and the total number of moles of gas present at the end of the reaction is 0.6809.

The ideal gas equation gives the approximate amount of PH₃ produced

and the gas at the conclusion as 0.28 and 0.69 moles respectively.

Response:

First part:

The PH₃ gas produced is approximately 0.28 moles

Second part:

The number of moles of gas present at the conclusion of the reaction is approximately 0.69 moles

What is the ideal gas equation, and how does it give the number of moles of gas present?

Given:

Mass of phosphorus = 8.50 g

Pressure of hydrogen gas, P = 2.00 atm

Volume of hydrogen gas, V = 10.0–L

Temperature of the gas, T = 298 K

First part:

From the ideal gas equation, P·V = n·R·T, we have;

[tex]Number \ of \ moles, \ n = \mathbf{\dfrac{P\cdot V}{R \cdot T}}[/tex]

Where for the hydrogen gas, H₂, we have;

P = 2.00 atm

V = 10.0 L

T = 298 K

The universal gas constant, R = 0.08205 L·atm·mol⁻¹·K⁻¹

Which gives;

[tex]n = \mathbf{ \dfrac{2.00 \times 10.0}{0.08205 \times 298}} \approx 0.82[/tex]

The number of moles of H₂ in the reaction, n0.82 moles

The equation of the reaction is; P₄(s) + 6H₂(g) [tex]\longrightarrow[/tex] 4PH₃(g)

Therefore;

1 mole of P₄(s) and 6 moles of H₂(g) produces 4 moles of PH₃(g)

Molar mass of P₄ ≈ 123.9 g

Which gives;

Number of moles in 8.50 g of phosphorus = [tex]\frac{8.5}{123.9}[/tex] ≈ 0.069

0.069 moles of P₄ will react with 0.069 × 6 moles ≈ 0.41 moles of H₂ to produce 0.069 × 4 moles ≈ 0.28 moles of PH₃

Number of moles of PH₃ gas produced is approximately 0.28 moles

Second part:

The total number of moles of gas present at the conclusion of the reaction is therefore;

∑Gas ≈ 0.28 moles + (0.82 - 0.41) moles ≈ 0.69 moles

Answers

Answer:

Boat conformation cis 1,4-dimethyl cyclohexane has the highest energy.

Explanation:

From the conformations, the boat conformation cis 1,4-dimethyl cyclohexane is least stable due to the fact that two methyl groups are located in opposite direction to each other, this leads to the production of  a higher strain. Similarly, Chair conformations appear more stable than boat conformation. Hence, energy is inversely proportional to stability. As a result of the aforementioned, boat conformation cis 1,4-dimethyl cyclohexane has the highest energy.
