Solutions for NCERT class 10 science chapter 1 Chemical Reactions and Equations- Exercise solutions

Q 1. Which of the statements about the reaction below are incorrect?

(a) Lead is getting reduced.

(b) Carbon dioxide is getting oxidized.

(c) Carbon is getting oxidized.

(d) Lead oxide is getting reduced.

(i) (a) and (b)

(ii) (a) and (c)

(iii) (a), (b) and (c)

(iv) all

Answer:

In the above reaction, PbO reduces to Pb and C(carbon) gets oxidized to carbon dioxide.

Hence, statements (a) and (b) are correct.

Thus, option (i) is correct.

Q 2. The above reaction is an example of a

(a) combination reaction.

(b) double displacement reaction.

(c) decomposition reaction.

(d) displacement reaction

Answer :

The above reaction is an example of a displacement reaction.

Hence, option (d) is correct.

Q 10. Why is respiration considered an exothermic reaction? Explain .

Answer:

We know that energy is required to support life. We get energy from the food we eat.

The large molecules of food are broken into a simpler substance like glucose during digestion.

Glucose and oxygen react to provide energy to the body. This reaction is a combination reaction named as respiration. In this whole process, energy is released so respiration is considered an exothermic reaction.

Q 16.(a) Explain the following in terms of gain or loss of oxygen with two examples each.

Oxidation

Answer:

Oxidation is a reaction in which the gain of oxygen or loss of hydrogen can be observed.

Example :

Q 16. (b) Reduction

Answer:

The reaction in which the loss of oxygen or gain of hydrogen can be observed is known as reduction reaction.

Example :

Q 18. Why do we apply paint on iron articles?

Answer:

To prevent iron from rusting paint is applied to iron articles. After applying paint iron articles are not in contact with moisture and air and hence rusting is prevented.

Q 19. Oil and fat containing food items are flushed with nitrogen. Why?

Answer:

We know that nitrogen is an inert gas and does not react with the oil and fat-containing food. Whereas, other gases like oxygen react with the oil and fat-containing food and make them rancid. Hence, to remove oxygen and prevent food from acidity food items are flushed with nitrogen.

Q 20. (b) Rancidity

Answer:

(b) Rancidity

The process of oxidation of fats and oils which can be noticed by a change in color, smell, and taste is known as rancidity.

Example: When butter is kept in the open atmosphere than its smell and taste change which results in rancidity.
