Question

an element X reacts with oxygen to form oxides oxide dissolves in water to form a solution which turns blue Litmus red this oxide reacts with Sodium Hydroxide to form salt the element excess carbon sodium calcium magnesium​

Answer 1

Answer:

Explanation:

• Oxide turn blue litmus into red. Hence it must be an acidic oxide. We know the oxides of non-metals are acidic in nature.
• The oxide also reacts with sodium hydroxide to form salt.

From the first point itself, we can conclude that the element in question is carbon.

The reaction of carbon with oxygen to form its oxide (carbon di oxide) is given by:

C + O₂ ⇒ CO₂

Reaction of CO₂ with NaOH to form salt is given by:

CO₂ + NaOH ⇒ NaHCO₃
