A sample of gas occupies 1.2 L at 12.0oC. Assuming pressure remains the same, what would be the volume (in L) of this gas at 67oC? A.
1.4

B.
1.0

C.
0.2

D.
5.0

E.
6.7

V1/T1 = V2/T2
V1 = 1.2 L
T1 = 12.0 + 273 = 285 K
T2 = 67.0 +273 = 340 K

1.2/285 = V2 / 340
V2 = 1.4 L

False, as a substance changes from a solid to a liquid and from a liquid to a gas the molecules get farther apart from each other

Answerit curves up and levels out.explanationwe assume that the container contains absolutely no ammonia to begin with as it states that "nitrogen gas and hydrogen gas" react to "produce ammonia."at dynamic equilibrium, the product and reactant concentrations are equal.this means that, starting from a concentration of zero, [nh₃] must curve "up" from zero and then level out to a constant concentration.
