Write and balance the equation
C7H16 + 11 O2 -> 7 CO2 + 8 H2O
According to the stoichiometry of the reaction one mol of heptane will react with 11 mol of molecular oxygen, then
1.42 mol O2 x 1 mol heptane/ 11 mol O2 = 0.129 mol
Answer:
C.remains at the same place
Answer:
Diffusion is driven by differences in concentration. When chemical substances such as perfume are let loose in a room, their particles mix with the particles of air. Diffusion in gases is quick because the particles in a gas move quickly. It happens even faster in hot gases because the particles of gas move faster.
