Ammonium hydrogen phosphate ((NH_(4))_(2)HPO_(4)) a common fertilizer, is made by reacting phosphoric acid (H_(3)PO_(4)) with ammonia according to the following reaction. 2NH_(3)+H_(3)PO_(4)arrow (NH_(4))_(2)HPO_(4) What is the ratio of NH_(3)toH_(3)PO_(4) NH_(3):H_(3)PO_(4)=2:1 √ comman How many moles of ammonia are needed to completely with 3 moles of phosphoric acid? square

To determine how many moles of ammonia are needed to completely react with 3 moles of phosphoric acid, we need to use the stoichiometric relationship from the balanced chemical equation.The balanced chemical equation is: From the equation, we see that 2 moles of ammonia (NH_3) are required to react with 1 mole of phosphoric acid (H_3PO_4).Given that we have 3 moles of phosphoric acid, we can set up a proportion to find the moles of ammonia needed: Solving for : Therefore, 6 moles of ammonia are needed to completely react with 3 moles of phosphoric acid.
