4) How many moles of HIO3 can be produced from the reaction of 635g of iodine trichloride and 118.5g of water? What was the limiting reagent? 2ICl3+3H2OICl+HIO3+5HCl 5) Magnesium oxide can be made by heating magnesium metal in the presence of oxygen. The unbalanced equation is: Mg(s)+O2MgO(s) When 10.1g of Mg is allowed to react with 10.5gO2,11.9gMg0 is collected. Determine the limiting reactant, theoretical yield and percent yield for the reaction
