Ncert chemistry (science) class 10 chapter 1​

Answer 1

Answer:

1 combination reaction

2 decomposition reaction

3 displacement reaction ( only a single product is displaced )

4 double - displacement reaction

Answer 2

Answer:

The correct answer of this question is Combination reaction, Displacement reaction, Decomposition reaction, Double - displacement reaction

Explanation:

Given - Predict the type of each reaction.

To Find - predict the type of each reaction.

(a) 2ag+S---Ag2S.

(b) NH4NO2---N2+2H2O.

(C) 2NAI+Cl2---2NaCl+l2.

(d) CuCl2+2NaOH---Cu(OH)2+2NaCl

Combination reaction is 2ag+S---Ag2S.

Decomposition reaction is NH4NO2---N2+2H2O.

Displacement reaction is 2NAI+Cl2---2NaCl+l2.

Double - displacement reaction is CuCl2+2NaOH---Cu(OH)2+2NaCl
