The size of a gas particle is negligibly small. The average kinetic energy of a particle is proportional to its temperature in kelvins. The collision of one particle with another (or with the walls of its container) is completely elastic.

Identify the combustion reaction. identify the combustion reaction. c (s) + o2 (g) → co2 (g) 2 h2 (g) + o2 (g) → 2 h2o (g) c3h8 (g) + 5 o2 (g) → 3 co2 (g) + 4 h2o (g) 2 c3h7oh (l) + 9 o2 (g) → 6 co2 (g) + 8 h2o (g) all of the reactions are examples
