c. dil sulphuric acid reacts with aluminium powder.
d. dil hydrochloric acid reacts with iron fillings.​

Answer 1

Answer:

a)h2so4+zn-- znso4 +h2

b)2hcl+mg - mgcl2 + h2

c)3h2so4+2al - al2(so4)3 +3h2

d)2hcl +fe - fecl2 +h2

Explanation:

Answer 2

Answer :-

a. Word equation:- Sulphuric acid(aq) + Zinc (s) → Zinc sulphate(aq) + Hydrogen(g)

Balanced equation:-

• $\rm{H_2SO_4(aq)+Zn(s)\longrightarrow{}ZnSO_4(aq)+H_2(g)}$

b. Word equation:- Hydrochloric acid(aq) + Magnesium(s) → Magnesium chloride(aq) + Hydrogen(g)

Balanced equation:-

• $\rm{2HCl(aq)+Mg(s)\longrightarrow{}MgCl_2(aq)+H_2(g)}$

c. Word equation:- Sulphuric acid(aq) + Aluminium(s) → Aluminium sulphate(aq) + Hydrogen(g)

Balanced equation:-

• $\rm{3H_2SO_4(aq)+2Al(s)\longrightarrow{}Al_2(SO_4)_3(aq)+3H_2(g)}$

d. Word equation:- Hydrochloric acid(aq) + Iron(s) → Iron chloride(aq) + Hydrogen(g)

Balanced equation:-

• $\rm{2HCl(aq)+Fe(s)\longrightarrow{}FeCl_2(aq)+H_2(g)}$

Additional Information :-

Balanced chemical equation:-

• A balanced chemical equation is a chemical equation in which the number of atoms of each element is equal on both sides of the arrow (the reactant side & the product side).

Single-displacement reaction:-

• All of the above given reactions are single-displacement or simply, displacement reactions. Displacement reaction is a type of chemical reaction in which a single atom or a group of atoms displace another atom or group of atoms of a compound.
