Question

B The allusions recall specific locations and horrors of the Vietnam conflict.How many moles of H2O are produced when 12 moles of NH3 reacts with excess O2?

4 NH3 + 5 O2 → 4 NO + 6 H2O



Group of answer choices

18 moles H2O


12 moles H2O


6 moles H2O


9 moles H2O

Answer 1

Answer: 18 moles of
`H_2O` will be produced.

Step-by-step explanation:

We are given:

Moles of ammonia = 12 moles

The given chemical equation follows:

`4NH_3+5O_2\rightarrow 4NO+6H_2O`

By the stoichiometry of the reaction:

4 moles of ammonia produces 6 moles of water

So, 12 moles of ammonia will produce =
`(6)/(4)* 12=18mol` of water

Hence, 18 moles of
`H_2O` will be produced.
