Prasad wrote a balanced chemical equation as `2C_(3)H_(8)+10O_(2)rarr 6CO_(2)+8H_(2)O`, but Pallavi argued it is not a balanced equation. Who is right ? Why ?

Text Solution

Verified by Experts

Pallavi's argument is correct. Because …………..
1) the chemical equation `2C_(3)H_(8)+10O_(2)rarr 6CO_(2)+8H_(2)O` is not a balanced equation.
2) in this equation the coefficients are not the smallest whole numbers.
3) it would be necessary to divide all coefficients by 2 to make it a balanced equation hence the balanced equation is `C_(3)H_(8)+5O_(2)rarr 3CO_(2)+4H_(2)O.`
