Using the balanced chemical reaction,

3 MgO(s) + 2 Fe(s) → Fe2O3(s) + 3 Mg(s)

calculate the number of grams of MgO needed to produce 15.0 g of Fe2O3.

If a molecule with a molecular formula of c13h18 is treated with an excess of h2 in the presence of finally divided pt metal under conditions required for maximum hydrogenation of the molecule to give a molecule with a formula c13h24, how many rings are in the molecule?

Me as soon as possible! me as soon as possible!

Question 5 match each term to its description. match term definition excess reactant a) reactant that can produce a lesser amount of the product limiting reactant b) reactant that can produce more of the product theoretical yield c) amount of product predicted to be produced by the given reactants
