Question

निम्न रासायनिक समीकरणों को संतुलित कीजि:
(a) C6H12O6 → Con+H2o+ ऊर्जा
(b) NaOH + H2SO4 → Na2SO4 + H2O (c) NaCl + AgNO3 → AgCl + NaNO3
(d) BaCl2 + H2SO4 → BaSO4 + HCl

Answer 1

Explanation:

Given -

• Chemical equation

To Do :-

• Balance the chemical equation

Solution :-

1)

When Glucose is break down in the presence of oxygen it decomposes to give carbon dioxide and water.

Chemical equation :-

C6H12O6 + O2 → 6CO2 + 6H2O

(Decomposition reaction)

2)

When sodium hydroxide and sulphuric acid reacts then it form sodium sulphate and water

Chemical equation :-

NaOH + H2SO4 → Na2SO4 + H2O

(Double displacement reaction)

3)

When sodium chloride is treated with silver nitrate then it forms silver chloride and sodium nitrate.

Chemical equation :-

NaCl + AgNO3 → AgCl + NaNO3

(Double displacement reaction)

4)

When barium chloride reacts with sulphuric acid then it forms barium sulphate and hydrochloric acid.

Chemical equation :-

BaCl2 + H2SO4 → BaSO4 + 2HCl

(Double displacement reaction)

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.

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.

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
