Given the reaction: 4nh3 +5o2 > 4no +6h2o

when 1.20 mole of ammonia reacts, the total number of moles of products formed is:

a. 1.20

b. 1.50

c. 1.80

d. 3.00

e.12.o

3 moles are produced with the reaction of 1.20 mol of NH₃  (Option 3)

Explanation:

The reaction is:

4NH₃  +  5O₂  ⇒  4NO  + 6H₂O

Therefore, 4 moles of ammonia react with 5 moles of oxygen, to produce 4 moles of nitrogen monoxide and 6 moles of water.

Ratio is 4:4 with NO and 4:6 with water.

1.20 mol of ammonia, would produce the same amount of NO and

(1.20 . 6) / 4 = 1.8 moles of water

Sum of moles of products formed is:

1.2 + 1.8 = 3 moles

acid rain does not usually kill trees directly. instead, it is more likely to weaken the trees by damaging their leaves, limiting the nutrients available to them, or poisoning them with toxic substances slowly released from the soil. the main atmospheric pollutants that affect trees are nitrates and sulphates.
