a) Write a balanced equation for the combustion of butane gas. b) If at a given moment butane is reacting at a rate of 0.400 mol L?1s?1, what are the rates of formation of products? c) What is the rate at which oxygen is reacting? I found the balanced equation, (2C4H10 + 13O2 --> 8CO2 + 10H2O) but I don't know how to get b and c from that
