A compound "P"is formed by the combination of one carbon atom and two oxygen atoms. a) Identify the compound P and write its chemical formula. (1) b) Write any one important use of the compound P. (1) c) Write any two properties of compounds. (1)Immersive Reader

a)Carbon (iv) oxide; CO₂

b)It is used in fire extinguishers

c) i. It is denser than air

ii. It dissolves in water to form an acidic solution

Explanation:

a) Since the compound P is composed of one atom of carbon and two atoms of oxygen, the formula of the compound is CO₂. The name of the compound is carbon(iv) oxide.

b) Carbon (iv) oxide is a gas that is of great importance to living organisms. Plants require it for photosynthesis while human produce it during the process of respiration.

Industrially, it is used in carbonated drinks. It is also used in fire extinguishers

c) The properties of Carbon (iv) oxide include the following:

i) it is an odourless colorless gas

ii) it is denser than air

iii) it dissolves in water to form a weak acidic solution, etc.

i think it is d. e because the next one is igneous.

- lead + phosphoric acid = hydrogen + lead(ii) phosphate
