Question
(a)name the product formed and write balanced chemical equation when water
reacts with (i)carbon
(ii) potassium oxide (iii) cerbon dioxide
(b) ) Define exothermic reaction with an example,
(i) Define endothermic reaction with an example,(ii)difine endothermic reaction with an example
(c) Give the composition, cause and impact of acid rain​

Answer 1

Answer:

a) i) C + H2O ---> CO + H2

ii) K2O + H2O -----> 2KOH

iii) CO2 + H2O ----> H2CO3

b) Exothermic reaction releases heat energy.

Eg: Rusting of iron

i) Endothermic reaction absorbs heat energy.

Eg: Melting of ice cube

c) Acid rain is caused by a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are released into the air. These substances can rise very high into the atmosphere, where they mix and react with water, oxygen, and other chemicals to form more acidic pollutants, known as acid rain.
