Ammonium phosphate is an important ingredient in many solid fertilizers. It can be made by reacting aqueous phosphoric acid with
liquid ammonia. Calculate the moles of phosphoric acid needed to produce of ammonium phosphate. Be sure your answer has a unit symbol, if necessary, and round it to the correct number of significant digits.
The given reaction is incomplete. The complete reaction is as follows.
Ammonium phosphate is an important ingredient in many solid fertilizers. It can be made by reacting aqueous phosphoric acid with liquid ammonia. Calculate the moles of phosphoric acid needed to produce 1.30 mol of ammonium phosphate. Be sure your answer has a unit symbol, if necessary, and round it to the correct number of significant digits.
Explanation:
Chemical equation for the given reaction is as follows.
Therefore, moles of required will be calculated as follows.
= 1.30 mol
Therefore, we can conclude that the moles of phosphoric acid needed to produce 1.30 mol of ammonium phosphate are also 1.30 mol.
Melting occurs when a solid is heated and turns to liquid. The particles in a solid gain enough energy to overcome the bonding forces holding them firmly in place. Typically, during melting, the particles start to move about, staying close to their neighboring particles, then move more freely.
The balanced equation for the neutralisation reaction is as follows 2HNO₃ + Ba(OH)₂ ---> Ba(NO₃)₂ + 2H₂O stoichiometry of HNO₃ to Ba(OH)₂ is 2:1 number of Ba(OH)₂ mol present - 0.108 mol 1 mol of Ba(OH)₂ neutralises 2 mol of Ba(OH)₂ therefore 0.108 mol of Ba(OH)₂ neutralises - 2 x 0.108 mol = 0.216 mol of HNO₃
The intermolecular forces between water molecules are stronger than those between oxygen molecules. In general, the bigger the molecule, the stronger the intermolecular forces, so the higher the melting and boiling points.
