Write the balanced chemical reaction for the formation of fe2(so4)3 from fe2o3 and so3 and determine how many moles of fe2(so4)3 are formed when 12.7 mol of so3 are reacted.

Tinererining 01: 57: 44 which statement correcte describes the actual veld and the theoretical yield of a reaction? textual vec is calculated to the reactant amounts but the theoretical yeld must be measured for each instance of a the actual vec is calculated from the amount of the limiting reactant and the theoretical yield is calculated from the 发公主 the actual weld depends on the reaction centers, but the theoretical yield and only with reactant amounts the actual vele represents the maximum weld possible and the theoretical yield assumes perfect reaction conditions save and ext e அட
