Balance the reaction. CH + 02 = 2 II CO2 + 3 H20 a). if 4.50 moles of C2H6 are used, how many moles of oxygen are required? Moles of Oxygen O2 moles b). if 0.3 moles of H2O were produced, how many grams of carbon dioxide would also have been produced? Grams of Carbon Dioxide CO2 00 g c). If you wanted to produce 5 moles of carbon dioxide, how many moles of oxygen would you needed to have started with? Moles of Oxygen O2 Balance the equation. Al + HCl = = H2 + AlCl3 What is the volume at STP of H2 that is produced if 30.5g of Al reacts completely? The volume of H2 is
