Answer: Option (D) is the correct answer.
Explanation:
When we write a chemical equation then reactants are written on left hand side and products are written on right hand side.
For example, [tex]SiH_{4} + 2O_{2} \rightarrow SiO_{2} + H_{2}O[/tex]
[tex]SiH_{4}[/tex] is the formula of silane. Here, both [tex]SiH_{4}[/tex] and [tex]2O_{2}[/tex] are the reactants. Whereas both [tex]SiO_{2}[/tex] and [tex]H_{2}O[/tex] are the products.
Hence, we can conclude that the chemical equation silane + oxygen [tex]\rightarrow[/tex] silicon dioxide + water, represents a chemical reaction.
