Question

What are the chemical properties of carbon dioxide ? explain each by showing reaction .​

Answer 1

Explanation:

Oxidation reactions, Addition reactions, Substitution reactions and Combustion reactions. Carbon burns in the presence of oxygen, it produces heat and light.

Answer 2

Chemical properties of Carbon:

(i) Reaction with oxygen: Carbon has a great affinity for oxygen. In excess supply of oxygen, it forms carbon dioxide. In limited supply of oxygen it forms carbon monoxide, which is a poisonous gas.

carbon + oxygen → carbon dioxide+heat

C O CO

2

In limited supply of air,

carbon + oxygen→ carbon monoxide+heat

C O 2CO

2

(ii) Reaction with hydrogen: Carbon reacts with hydrogen at 500°C and 250 atmospheric pressure to form a mixture of hydrocarbons like ethane, methane etc.

carbon + hydrogen → methane

C 2H CH

2 4

(iii) Carbon as reducing agent:

(a) Carbon reduces metal oxides to form metal and carbon monoxide.

ZnO + C → Zn + CO

(b) Carbon reduces concentrated sulphuric acid to form SO2 and conc. nitric acid to form NO2 .

C + 2H2SO4 → CO2 + 2H2O + 2SO2

C + 4HNO3 → CO2 + 2H2O + 4NO2
