Question

For the balanced chemical equation shown below, what are the coefficients in order from reactants to products? nh3 + o2 → no + h2o

Answer 1

The answer is coefficient of reactant is 4,3 and product is 4,2

Balance chemical is as follows:

4NH₃ + 3O₂ ------>4NO+ 2H₂O

So the coefficient of reactant is 4,3

While that of product is 4,2

So the answer is coefficient of reactant is 4,3 and product is 4,2

Answer 2

Step-by-step explanation:

A chemical reaction equation that contains same number of atoms on both reactant and product side is known as a balanced chemical equation.

For example,
`NH_(3) + O_(2) \rightarrow NO + H_(2)O`

Number of atoms present on reactant side are as follows.

N = 1

H = 3

O = 2

Number of atoms present on product side are as follows.

N = 1

H = 2

O = 2

Hence, in order to balance this equation we multiply
`NH_(3)` by 2 and
`O_(2)` by
`(5)/(2)` on reactant side. Whereas multiply NO by 2 and
`H_(2)O` by 3 on product side.

Therefore, the balanced chemical reaction equation is as follows.

`2NH_(3) + (5)/(2)O_(2) \rightarrow 2NO + 3H_(2)O`

So, coefficients of reactants are 2 and
`(5)/(2)`. On the other hand, coefficients of products are 2 and 3.
