Answer:
Explanation:
First You must know this
Oxidation number for H = +1 and for O = -2
let C unknown
the total charge for molecule is ZERO
SO =>> 2(X) + 2(+1) + 4(-2) = 0 ( 0 -> for total charge )
so 2X + 2 + ( -8 ) = 0
2X + 2 - 8 = 0 ( Take 8 and 2 to another side and change the sign )
2X = 8 - 2 ( Divide by 2 to calculate the value of x )
X = 8 - 2 ÷ 2
X = 6 ÷ 2 = 3
So the oxidation number for one Carbon is +3 , for two is +6
2C = +6 , 2H = +2 , 4O = -8 ( the total Charge is ZERO ( 8-8 = 0 )
GOOD LUCK
