Zinc + Oxygen Gas $\to$ Zinc Oxide (Word Equation)

$2 \text{Zn"(s) + "O"_2(g) -> 2"ZnO} \left(s\right)$ (Balanced Chemical Equation)

#### Explanation:

Zinc reacts with oxygen gas to produce zinc oxide

$2 \text{Zn" + "O"_2 -> 2"ZnO}$

(The total mass of the products has to be equal to the total mass of the reactants $\to$ refer to the law of conservation of mass and energy).
