Balance the following equation: H2O(l) → H2 (g) + O2 (g)

2 H2O(l) → 2 H2(g) + O2(g)

Explanation:

H2O(l) → H2 (g) + O2 (g)

Add 2 to both sides:

Reactants:               Products:

H: 2+2=4                    H: 2+2=4

O: 1+1=2                      O:2

2 H2O(l) → 2 H2(g) + O2(g)

Therefore it is balanced, hope this helps.

answer: a tank of height h is filled with water and sits on the ground. water squirts from a hole at a height y above the ground and has a range r. for two y values, 0 and h, r is zero. determine the value of y for which the range will be a maximum.
