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
Verified answer
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.
