Hint-2

For a complete explanation, watch:

When balancing chemical equations our goal is to have the same number of each type of atom on both sides of the equation.

Only change the coefficients (these are the numbers in front substances).
Coefficients are the numbers in front of the molecule.

Never change the subscripts (the small numbers after elements).
Coefficients are the numbers in front of the molecule.
