Gaseous hydrogen can be reacted with gaseous oxygen in the presence of a flame to produce water vapor according to the following reaction:

[mathjax] \text{ a } \text{H}_{2 } + \text{ b }\text{O}_{2 } = \text{ c }\text{H}_{2 }\text{O }[/mathjax]

Balance the equation i.e., specify the values of a, b, and c. Use the lowest whole number coefficients.

a =

b =

c =
