Chemical Equation Solving Quiz

Can you fill in the coefficients, which balance the equation?

For example _ CH4 + _ O2 → _ CO2 + _ H2O would be balanced by 1 CH4 + 2 O21 CO2 + 2 H2O

"Ones" must be written too.
You might wanna use a piece of paper for some of them.
For the last one some coefficients have to be given for its solvability.
