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

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

Explanation:

Zinc reacts with oxygen gas to produce zinc oxide

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

(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).
