Balanced chemical reaction 1: Ag₂CO₃(s) ⇄ 2Ag⁺(aq) + CO₃²⁻(aq).
Balanced chemical reaction 2: H₂CO₃(aq) + H₂O(l) ⇄ HCO₃⁻(aq) + H₃O⁺(aq).
Balanced chemical reaction 3: HCO₃⁻(aq) + H₂O(l) ⇄ CO₃²⁻(aq) + H₃O⁺(aq).
Balanced chemical reaction 4: H₂O(l) ⇄ H⁺(aq) + OH⁻(aq).
H₂CO₃ and HCO₃⁻ are acids and lose protons to water.

Which of the following is a nonmetallic mineral resource?. A. wood . B. iron . C. coal . D. aggregate
sesenic [268]

Answer: The correct option is D.

Explanation: Nonmetallic minerals are the chemical elements from which no new product can be formed when they are melted. For Example: Sand, marble etc..

For the given options:

Option A: Wood is a type of cellulose and is not considered as a nonmetallic mineral resource.

Option B: Iron is an element because it is the smallest substance which cannot be broken down. It is not considered as a nonmetallic mineral resource.

Option C: Coal is a mixture of carbon compounds. This is very close to mineral but is an organic mineral because it contains carbon atom. Hence, it is not considered as a nonmetallic mineral resource.

Option D: Aggregate is  formed by the collection of particles forming a whole mass. This is a non-metallic resource as it cannot form any new product.

Hence, the correct option is D.
