A syringe initially holds a sample of gas with a volume of 285 mL at 355 K and 1.88 atm. To what temperature must the gas in the

Ivahew [28]

Answer: The temperature to which the gas in the syringe must be heated is 720.5 K

Explanation:

To calculate the volume when temperature and pressure has changed, we use the equation given by combined gas law.

The equation follows:

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

where,

$P_1,V_1\text{ and }T_1$ are the initial pressure, volume and temperature of the gas

$P_2,V_2\text{ and }T_2$ are the final pressure, volume and temperature of the gas

We are given:

$P_1=1.88atm\\V_1=285mL\\T_1=355K\\P_2=2.50atm\\V_2=435mL\\T_2=?K$

Putting values in above equation, we get:

$\frac{1.88atm\times 285mL}{355K}=\frac{2.50atm\times 435mL}{T_2}\\\\T_2=\frac{2.50\times 435\times 355}{1.88\times 285}=720.5K$

Hence, the temperature to which the gas in the syringe must be heated is 720.5 K

H. Nitrogen gas and hydrogen gas combine to produce ammonia gas (NH3).

DedPeter [7]

Answer:

27.3 L

Explanation:

Reaction

N₂ (g) + 3H₂ (g) ⇒ 2NH₃ (g)
This is the basic reaction at STP

Solving

10 g N₂ x 1 mol NH₃/28 g N₂ x 3 mol H₂/1 mole N₂
⇒ 1.07 mol H₂

V = nRT/P [From Ideal Gas Equation]
V = 1.07 x 62.36 x 298 K / 735
V = 27.3 L
