Answer:

302.8K

Explanation:

Using Charles law equation;

V1/T1 = V2/T2

Where;

V1 = initial volume (L)

V2 = final volume (L)

T1 = initial temperature (K)

T2 = final temperature (K)

According to the information provided in this question;

V1 = 545L

V2 = 550L

T1 = 27°C = 27 + 273 = 300K

T2 = ?

Using V1/T1 = V2/T2

545/300 = 550/T2

1.82 = 550/T2

Cross multiply

1.82 T2 = 550

T2 = 550/1.82

T2 = 302.8K

<h2>The new volume of the balloon at the top of Pikes Peak is 10.2 L</h2>

Explanation:

Combined gas law is the combination of Boyle's law, Charles's law and Gay-Lussac's law.

The combined gas equation is,

$\frac{P_1V_1}{T_1}=\frac{P_2V_2}{T_2}$

where,

$P_1$ = initial pressure of gas = 577.0 torr

$P_2$ = final pressure of gas = 400 torr

$V_1$ = initial volume of gas = 7.4 L

$V_2$ = final volume of gas = ?

$T_1$ = initial temperature of gas = $20.6^oC=273+20.6=293.6K$

$T_2$ = final temperature of gas = $7.5^oC=273+7.5=280.5K$

Now put all the given values in the above equation, we get:

$\frac{577.0\times 7.4}{293.6K}=\frac{400.0\times V_2}{280.5K}$

$V_2=10.2L$

Thus the new volume of the balloon at the top of Pikes Peak is 10.2 L

Virty [35]

Explain whether this is a chemical or physical change, and why. does it involve elements, compounds, mixtures, or pure substances?

If the process involves a chemical reaction then surely it is a chemical change where new bonds are being formed from the collision of the reactants.

Describe how many atoms are involved before and after. what do you notice about the number of atoms?

From the balanced chemical reaction, we see that we need 1 mol of N2 gas and 3 mol of H2 in order to form 2 mol of NH3.
