32. Sulfuric acid dissolves aluminum metal according to the reaction: 2Al(s)+3H2SO4(aq)Al2(SO4)3(aq)+3H2(g) Suppose you want to dissolve an aluminum block with a mass of 15.2g. What minimum mass of H2SO4 (in g) do you need? What mass of H2 gas (in g ) does the complete reaction of the aluminum block produce? 40. Calculate the theoretical yield of product (in moles) for each initial a mount of reactants. 3Mn(s)+2O2(g)Mn3O4(s) a. 3molMn,3molO2 b. 4molMn,7molO2 c. 27.5molMn,43.8molO2
