Consider the single replacement reaction between 27.5 g of sodium and 65.0 g of nickel (II) phosphate, Na + Ni3(PO4)2 → 2a) How many grams of sodium phosphate can theoretically be produced? 2b) What is the excess reactant? 2c) How many grams of the excess reactants will remain when the reaction is complete? 2d) If the actual experiment produced 53.1 g of sodium phosphate, what is the percent yield of this trial?
