Question

Q - 2H2 + 02 →2H20 is an example of *

(a) displacement reaction

(b) decomposition reaction

(c) combination reaction

(d) isomerisation reaction​

Answer 1

Answer:

the answer should be combination displacement

Answer 2

Answer:

(b) Decomposition Reaction

Explanation:

There are main four kinds of chemical reactions:

1) Combination Reaction

2) Decomposition Reaction

3) Displacement Reaction

4) Double Decomposition Reaction

Decomposition Reaction is further three types of:

• Thermal decomposition reaction
• Electrical decomposition reaction
• Photo decomposition reaction

2H2 + O2 → 2H2O is an example of Electrical decomposition reaction or Water splitting reaction as electricity is required in it.

Decomposition reaction is a reaction in which two or more reactants combine to form a single product.
