Question

1. Write two examples of each of displacement and

double displacement examples.​

Answer 1

Answer:

The reaction in which there is an exchange of ions between the reactant takes place is called double displacement reaction. A and C are Cations (Positive Ions) B and D are Anions (Negative Ions) Double Displacement Reaction For examples: Na2SO4 + BaCl2→ BaSO4 + 2NaCl Sodium Barium Barium Sodium sulphate chloride sulphate chloride AgNO3 + NaCl → AgCl + NaNO3 Silver Sodium Silver Sodium nitrate chloride chloride nitrateRead more on Sarthaks.com - https://www.sarthaks.com/941228/give-two-examples-each-of-double-displacement-reactions

Answer 2

Explanation:

Displacement reaction:

(i) CuSO4 ( aq) +zn(s) =ZnSO4(aq) +Cu(s)

(ii) CuSO4(aq) +Mg(s) =MgSO4(aq) +Cu(s)

Double displacement reaction:

(i) BaCl2(aq) +CuSO4(aq) =BaSO4(s) +CuCl2(aq)

(ii) CuSO4(aq) +H2S(g) =CuS(s) +H2SO4(aq)
