The combustion of butane produces heat according to the equation
2C4H10(g) + 13O2(g) → 8CO2(g) + 10H2O(l) %media:formula3.mml% = -5,314 kJ/mol
What is the heat of combustion per gram of butane?
14 g of Si reacts with 16 g of O to produce SiO2, the only product, with no reactant left over. How much SiO2 would be produced from 34 g of Si and excess O?
