Question

What is the sum of the equation water plus hydroxide of a metallic element? Option a) Hydrogen gas Option b) Sodium chloride Option c) Sodium hydroxide Option d) Oxygen gas

Answer 1

Option c) Sodium hydroxide.

Step-by-step explanation:

The sum of the equation water plus hydroxide of a metallic element results in the formation of a metal hydroxide and hydrogen gas123. The balanced chemical equation for this reaction is:

Metal + Water → Metal Hydroxide + Hydrogen

For example, when sodium reacts with water, it forms sodium hydroxide and hydrogen gas:

2Na (s) + 2H2O (l) → 2NaOH (aq) + H2(g)4.

Therefore, the correct answer is Option c) Sodium hydroxide.
