Question

Give balanced chemical equations for each of the decomposition reaction carried out with the help of 1 electricity 2 heat 3 sunlight

Answer 1

Explanation:

Balanced chemical equation of the decomposition reaction carried out with the help of

1) Electricity -

Chemical equation :-

2H2O → 2H2 + O2

2) Heat :-

Chemical equation :-

CaCO3 → CaO + CO2

3) Sunlight :-

Chemical equation :-

2AgCl → 2Ag + Cl2

Additional information :-

Types of chemical reaction :-

• Combination reaction -

Those reaction in which two or more substances combined to form a single substance, are called combination reaction.

Example -

C + O2 → CO2

• Decomposition reaction -

Those reaction in which a compound splits up into two or more simpler substances are known as decomposition reaction.

decomposition reaction.

Example -

CaCO3 → CaO + CO2

• Displacement reaction -

Those reaction in which one element takes the place of another element in a compound, are known as Displacement reaction.

Displacement reaction.

Example -

CuSO4 + Zn → ZnSO4 + Cu

• Double Displacement reaction -

Those reaction in which two compounds react by an exchange of ions to form two new compounds are called double displacement reaction.

Example -

AgNO3 + NaCl → AgCl + NaNO3
