Vedclass · Answer

(C) Magnesium $(Mg)$ is a moderately reactive metal.$1$. It burns in oxygen with a dazzling white flame to form magnesium oxide $(2Mg + O_2 ightarrow 2MgO)$. This statement is correct.$2$. Magnesium does not react with cold water. It reacts with hot water to form magnesium hydroxide and hydrogen gas $(Mg + 2H_2O 	ext{ (hot)} ightarrow Mg(OH)_2 + H_2)$. This makes option $C$ incorrect because it claims reaction with cold water.$3$. Magnesium reacts with steam to form magnesium oxide and hydrogen gas $(Mg + H_2O 	ext{ (steam)} ightarrow MgO + H_2)$. Note: Option $D$ is also technically incorrect as it states magnesium hydroxide is formed with steam, but option $C$ is the most fundamentally incorrect statement regarding cold water reactivity.
