Upon the addition of heat to an unknown amount of KClO3, 0.48 g of oxygen was produced. How many grams of KClO3 reacted?
For the reaction: 2Fe + 3CuCl2 = 2FeCl3 + 3Cu. 10g of Fe and 18.0g of CuCl2 are mixed together and a reaction occurs.
Determine the mass of CO2 and H2O produced on combusting 140 g of C2H2 in the presence of excess O2.
