Answer 1

Answer:

hope this will help you thankyou very much

Answer 2

Breaking of the chemical bonds and formation of new chemical bonds is responsible for the occurrence of a chemical reaction. The reactions occur in presence of chemical reagents. Thus, A is true but R is false. The correct option is C.

Explanation:

• In a chemical reaction, some chemical bonds are broken while some chemical bonds are formed.
• This breaking and formation of chemical bonds is the reason for the occurrence of a chemical reaction.
• The reacting species in a chemical reaction are called reactants while the formed species are called products.
• The chemical reactions take place in the presence of chemical reagents, appropriate temperature and other reaction conditions.
