Barium nitrate reacts with phosphoric acid according to the reaction shown below. What mass of barium phosphate can be produced if 9.11 g of barium nitrate reacts with 13.0 g of phosphoric acid? 3Ba(NO3)2(aq) + 2H3PO4(aq) = Ba3(PO4)2(s) + 6HNO3

Iknow #2 is d. i just need to know why

1.aluminum chloride (alcl3), and sodium hydroxide (naoh) can react to form aluminum hydroxide (al(oh)3) and sodium chloride (nacl).    you have 13.4 g of aluminum chloride and 10.0 g of sodium hydroxide. answer the following questions: •what is the balanced equation for this reaction? •if you use all 13.4 g of aluminum chloride, how many grams of aluminum hydroxide can be formed? work must be shown to earn credit •if you use all 10.0 g of sodium hydroxide, how many grams of aluminum hydroxide can be formed? work must be shown to earn credit •how many grams of aluminum hydroxide will actually be made?     which reagent is limiting? explain your answer.

Avariable that is not being directly tested during an experiment should be
