The moles of ammonia that are needed to react completely with 3 moles of phosphoric acid is <u> 6 moles</u>

<u><em>Explanation</em></u>

Step 1:

write the a balanced chemical reaction that occur between ammonia and phosphoric acid.

Step 2: use of mole ratio of NH3 :H3PO4 to calculate moles of NH3

that is, NH3: H3PO4 is 3:1 therefore the moles of NH3 = 3moles x 3/1 = 9 moles

3 moles of NH3 was in excess therefore the mole of NH3 that reacted = 9-3 = 6 moles

Energy is stored in chemical bonds during photosynthesis.

During photosynthesis, the radiant energy from the sun is converted to chemical energy in carbohydrates.

Inorganic materials in the form of carbon dioxide and oxygen combine to form carbohydrates in the presence of radiant energy according to the equation below:

$6CO_2 + 6H_2O ---> C_6H_1_2O_6 + 6O_2$

The energy is thus, stored in chemical bonds in the carbohydrate and this is what is oxidized during respiration to release the locked energy.
