Question

Match Column I with Column II and rewrite the equation to the reaction type.
Column I
Column II

(i) AgNO3(aq) + NaCl(aq) → AgCl(s) +  NaNO3(aq)
(ii) H2(g) + Cl2(g) → 2HCl(g)
(iii) 2NaOH + H2SO4 → Na2SO4 + 2H2O
(iv) 2Cu(NO3)2 → 2CuO + 4NO2 + O2
(A) Neutralisation reaction
(B) Decomposition reaction
(C) Precipitation reaction
(D) Redox and combination  reaction
​

Answer 1

Answer:

4,1,3,2

Explanation:

this is the correct answer

Answer 2

Answer:

1-c

2-d

3-a

4-b

1st is double displacement and thus it is also precipitation reaction

2nd is combination and redox cause "cl" gains hydrogen

3rd is neutralisation

acid+ base= salt + water

4th is decomposition reaction cause it get broken down in simpler elements
