Answer:

 2H₂   +   O₂  →   2H₂O

Explanation:

The expression of the equation is given as:

              _H₂   +   2O₂  →   2H₂O

Now for expression above,

                           Reactants                                          Products

H                              2                                                            4

O                              4                                                           2

to balance the equation, we use 2 moles of hydrogen gas and 1 mole of oxygen gas;

           2H₂   +   O₂  →   2H₂O
