Ammonium phosphate ((nh), po) is an important ingredient in many fertilizers. it can be made by reacting phosphoric acid (ti, po.) with ammonia (nh) what mass of ammonium phosphate is produced by the reaction of 7.5 g of ammonia? be sure your answer has the correct number of significant digits.

22.35 g of  (NH₄)₃PO₄ will be produced by 7.5 g of ammonia.

Explanation:

H₃PO₄ + 3NH₃  → (NH₄)₃PO₄

H₃PO₄: 98 g/mol

NH₃: 17 g/mol

(NH₄)₃PO₄: 149 g/mol

17 g NH₃ 1 mol

7.5 g NH₃ x

  x = 0.44 mol NH₃

3 mol NH₃ 1 mol (NH₄)₃PO₄

0.44 mol NH₃           y

     y = 0.15 mol (NH₄)₃PO₄

1 mol (NH₄)₃PO₄ 149 g

0.15 mol (NH₄)₃PO₄    z

          z = 22.35 g (NH₄)₃PO₄

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
