STUDENTS PLS ANSWER THIS QUESTION SERIOUSLY AS I HAVE MY PERIODICALS AND HAVE TO GET HEAVY MARKS AND I PROMISE THAT IF YOU WILL ANSWER IT CORRECTLY THEN I WILL MARK YOU AS THE BRAINLIEST SO PLS HELP............................ IT WILL GIVE YOU HUNDRED POINTS

Answer 1

Answer:

ANSWER

The chemical reaction taking place in the flask is-

Zn

(s)

+

(Dil.)

H

2

SO

4

(aq.)

⟶ZnSO

4

(s)

+H

2

(g)

Zinc reacts with dilute sulphuric acid to produce hydrogen gas (H

2

) and zinc sulphate.

Thus the gas evolved in the reaction is hydrogen.

Hydrogen is a nontoxic, tasteless and highly combustible diatomic gas.

Answer 2

In all the above situations, the nature and the identity of the initial substance have somewhat changed. We have already learnt about physical and chemical changes of matter in our previous classes. Whenever a chemical change occurs, we can say that a chemical reaction has taken place.
