Question

how to balance an equation of 10th std new syllabus?

Answer 1

Balancing any equation is very easy. There is nothing vast in that for balancing you have to look the number of atoms of reactans as well as product.

For example:- h2+o2 gives h2o

So, now see the number of atoms are not eqal in the both sides in reactants as well as in product so, for balancing the eqation we have to take a look on the number of the atoms in reactants the number of hydrogen is 2, oxygen is 2 and in the product side the number of hydrogen is 2, and the nunber of oxygen is 1

So, fir making it balance we have to multiply by 2 in the reactants side the hydrogen gets 4 and oxygen remains same (2) and after that we will multiply by 2 in the product side so by that the hydrogen will become 4 and oxygen will become 2. This is the process if balancing any eqation.
