Using the combined gas law, if the volume of a gas at 155kPa changes from 22L to 10L. What is the new pressure if the temperatur
Deffense [45]

Answer:

The answer to your question is  P2 = 342 kPa

Explanation:

Data

Pressure 1 = P1 = 155 kPa

Volume 1 = V1 = 22 l

Pressure 2 = P2 = ?

Volume 2 = V2 = 10 l

Temperature = constant

Process

1.- Write the equation of the combined gas law

                 P1V1/T1 = P2V2/ T2

Cancel T1 and T2 because they measure the same

                 P1V1 = P2V2

-Solve for P2

                 P2 = P1V1/V2

2.- Substitution

                 P2 = (155 x 22) / 10

3.- Simplification

                 P2 = 3410 / 10

4.- Result

                 P2 = 342 kPa

N2 + 3H2, -&gt; 2NH3<br> If I have 50.6 L of N2 and excess H2, how many liters of NH3 can I produce?
Anastaziya [24]

Answer:

C. 101.2 L

Explanation:

N2 + H2= NH3

Balancing it,

N2 + 3 H2 = 2.NH3

(1 mol) (3 mol) (2 mol)

which means

1 molecule of nitrogen reacts with 3 molecule of hydrogen to form ammonia.

Likewise,

50.6 l of nitrogen reacts with 50.6 × 3= 151.8 l of hydrogrn to form 50.6 × 2= 101.2 l of ammonia.
