Question

Students performing a chemistry experiment reacted nitrogen gas and oxygen gas. They found that 20.0 mL of N2(g) reacted with 40.0 mL of O2(g) to produce 40.0 mL of NO2(g). In order to produce 1.0 L of NO2(g) they would need to use _____L of N2(g) *

a) 1.0 L

b) 2.0 L

c) 0.5 L

d) 0.25 L

Answer 1

N2 + 2O2 = 2NO2

n(NO2) : n(N2) = 2 : 1

V(NO2) : V(N2) = 2 : 1

Answer: c) 0.5 L
