Question

From the data presented in the report sheet, you can deduce that the stoichiometric coefficient for oxygen is _______.
H20 (1) --> H2 (g) + O2 (g)

Answer 1

Answer: The stoichiometric coefficient for oxygen is $\frac{1}{2}$.

Explanation:

A number present on the front of an atom, ion or molecule in a chemical reaction equation is called a stoichiometric coefficient.

For example, $H_{2}O(l) \rightarrow H_{2}(g) + \frac{1}{2}O_{2}(g)$

Here, the stoichiometric coefficient for $H_{2}O(l)$ is 1, for $H_{2}(g)$ is 1 and for $O_{2}$ is $\frac{1}{2}$.

Thus, we can conclude that the stoichiometric coefficient for oxygen is $\frac{1}{2}$.
