Answer 2

Answer:

make sure the both sides are equal for eg 2H2 + O2 -> 2H20

Explanation:

in the above example there is 2H2 which means there is 2x2(4) molecules of hydrogen on left side and on the right side there is 2H2 which is also 2×2(4) and on the left side there is O2 that is 2 molecules and on right side there is 2×1 as 2 in 2H2O applies both for H and O thus both H and O are equal on both sides
