C2H5OH (l) + O2(g) 2 CO2(g) + 3 H2O (g). The law of conservation of mass says that matter cannot be created or destroyed, which means there must be the same number atoms at the end of a chemical reaction as at the beginning. Tng hp cc cht ha hc y nht ti Cunghocvui. A compound with a molar mass of about 28 g/mol contains 85.7% carbon and 14.3% hydrogen by mass. jangan lupa di share ya . CxHy(g) + O2(g) CO2(g) + H2O(l). So if we take those ratios from before and scale them up to larger number, we will still have the same ratio of carbon and oxygen atoms to molecules of carbon dioxide. b.
