Question

write the reaction where displacement reaction is possible also state the reason class 10​

Answer 1

Answer:

Ans: Magnesium is an very reactive metal. When stored, it reacts with oxygen to form a layer of magnesium oxide on its surface. This layer of magnesium oxide is quite stable and prevents further reaction of magnesium with oxygen. The magnesium ribbon is cleaned by sand paper for removing this layer so that the underlying metal can be exposed to air.

2. Write the balanced equation for the following chemical reactions.

(a) Hydrogen + Chlorine → Hydrogen chloride

(b) Barium chloride + Aluminium sulphate → Barium sulphate + Aluminium chloride

(c) Sodium + Water → Sodium hydroxide + Hydrogen

Ans: (a) H2 (g) + Cl2 (g) → 2HCl (g)

(b) 3BaCl2 (s) + Al2(SO4)3 (s) → 3BaSO4(s) + 2AlCl3 (s)

(c) (c) 2Na(s) + 2H2O (l) → 2NaOH (aq) + H2 (g)

Answer 2

Answer:

A single-displacement reaction, is a chemical reaction in which one element replaces an/other element in a compound. It can be represented generically as: A + B-C → A-C + B This will most often occur if A is more reactive than B, thus giving a more stable product.

1. Na2So4 + BaCl2 arrow NaCl2+ BaSo4
2. 2NaBr(aq) → 2NaCl(aq) + Br2(aq)
3. 2AgNo3(aq) → 2Ag(s) + Cu(NO3)2(aq)

are an example of displacement reaction.

Some other examples of displacement reactions which can occur are: zinc displacing iron ions from iron(II) sulfate solution. nickel displacing copper from copper(II) nitrate solution. copper displacing silver from silver(I) nitrate solution.
