Question

Write examples with chemical equations for the below reactions. at least one

1.Thermal Decomposition
2. Double Displacement.
3. Exothermic reaction.
​

Answer 1

Answer:

Reactants are converted to products, and the process is symbolized by a chemical equation. For example, iron (Fe) and sulfur (S) combine to form iron sulfide (FeS). Fe(s) + S(s) → FeS(s) The plus sign indicates that iron reacts with sulfur

Answer 2

• Answer:-

1.Thermal Decomposition-

Ans-A thermal decomposition reaction can be defined as a decomposition reaction which is activated by thermal energy.

A common example of a thermal decomposition reaction-

CaCO³→ CaO + CO².

2.Double Displacement.

Ans-A double displacement reaction is a type of reaction in which two reactants exchange ions to form two new compounds. Double displacement reactions typically result in the formation of a product that is a precipitate.

Double displacement reactions take the form:

AB + CD → AD + CB.

3.Exothermic reaction.

Ans-Exothermic reactions are reactions or processes that release energy, usually in the form of heat or light

For example:

Firing a firecracker – the bursting of a firecracker gives out a loud noise in addition to light and heat
