Answers

Answered by BrainlyNisha001

Answer:

When zinc granules react with the diluted sulphuric acid, hydrogen gas and zinc sulphide are formed.

Chemical reaction formula:

Zn+H2SO4= ZnSO4 + H2

Characteristics of this chemical reaction:

1)Heat is generated , that's why it is an exothermic reaction.

2)This chemical reaction is also a reduction reaction.

Explanation:

When dilute sulphuric acid is poured over zinc granules then zinc sulphate and hydrogen gas is produced.

Chemical equation :-

Zn(s) + H2SO4(aq.) → ZnSO4(aq.) + H2(g)

Characteristics of this Chemical reaction is :-

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
