Question

how to balance chemical equations

Answer 1

first check the LHS and take one compound say carbon count how many carbons are there on the LHS , then move on to the RHS and count the no. of carbons multiply certain amount to balance it 

Answer 2

check RHS and LHS if on both sides the atoms are equal like if on right there are 2 hydrogens but on left only 2 multiply it by 2 hence equate on the other side in order to maintain the equation.
