10. Hydrogen gas reacts with oxygen gas to produce water, as shown below. 2 H2 + O2 —> 2 H2O
Approximately how many grams of hydrogen gas are needed to completely react with 128 grams
of oxygen gas?
A) 4g
B) 8 g
C) 16g
D) 32 g

Which element is the least metallic between cadmium, silver, zinc, or iron?

For the reaction, 4 a(g) + 3 b(g) => 2 c(g), the following data were obtained at constant temperature. experiment initial[a],mol/l initial [b],mol/l initial rate,m/min 1 0.200 0.150 5.00 2 0.400 0.150 10.0 3 0.200 0.300 10.0 4 0.400 0.300 20.0 which of the following is the correct rate law for the reaction? 1. rate = k[a]2[b]2 2. rate = k[a][b] 3. rate = k[a]2[b] 4. rate = k[a][b]2

Witch two conditions can limit the usefulness of the kinetic molecular theory in describing gas behavior?
