<p>Gaseous hydrogen can be reacted with gaseous oxygen in the presence of a flame to produce water vapor according to the following reaction:</p>
        [mathjax] \text{ a } \text{H}_{2 } + \text{ b }\text{O}_{2 } = \text{ c }\text{H}_{2 }\text{O }[/mathjax]
<p>Balance the equation i.e., specify the values of <i> a, b, </i> and <i>c</i>. Use the lowest whole number coefficients.</p>
