Question

How to balance, NH3+O2 gives NOH2O

Answer 1

Explanation:

NH3 + O2 = NO + H20

It is an example of double displacement reaction

so to balance the equation we should prove LHS=RHS

So in LHS.

N = 1 H=3 O=2

IN RHS

N=1 O=2 H=2

SO TO BALANCE IT.

IN LHS LETS ADD 4 to NH3

so now equation is

4NH3 + O2 = NO + H2O

IN LHS

N=4 H = 12

IN RHS

N=1 O=1 H=2 O=1

NOW IN ORDER TO MAKE RHS = LHS

we can see in RHS ,N=1 and In LHS N=4

SO not we should add 4 in RHS

NOW THE EQUATION IS

4 NH3 + O2 = 4NO + H2O

NOW WE CAN SEE IN LHS H = 4 x 3 = 12.

In RHS H = 2.

SO NOW WE SHOULD ADD 6 IN RHS in order to prove LHS = RHS

SO NOW THE EQUATION IS

4 NH3 + O2 + 4NO + 6 H2O

NOW,

IN LHS O = 2 AND IN RHS O = 6 + 4 = 10

IN LHS O = 2 AND IN RHS O = 6 + 4 = 10NOW IN ORDER TO MAKE LHS=RHS

IN LHS O = 2 AND IN RHS O = 6 + 4 = 10NOW IN ORDER TO MAKE LHS=RHS WE SHOULD ADD 5 IN LHS.

NOW THE BALANCED EQUATION IS:-

4 NH3 + 5 O2 = 4 NO + 6 H2O
