Answer:

2H2O+4NO2+O2=4HNO3

Step-by-step explanation:

LEFT HAND SIDE(L.H.S) RIGHT HAND SIDE(R.H.S)

N=1X10X2 =20 N=1X10X2=20

H=2X5X2 =20 H=1X10X2=20

O=1X5X2+10X2X2+2 X5 O=3X10X2=60

=60

First multiply H2O by 2 to get an even no. of oxygen on L.H.S

make a similar chart at every turn to record the changes in number.

then multiply R.H.S by 2 to equate the hydrogen

multiply N by 2 on LHS to equate them.

the no of O changes

Multiply RHS by 2 again,

equate the LHS by multiplying NO2 by 2 again, i.e total 4

you now have the answer
