                                    MATCH THE COLUMNS

1 . `H_2` + `CI_2` `→` 2HCI    a. displacement reaction
2. `2FeCI_3`+ `H_2`  `→` `2FeCI_2` +2HCI` b. addition of an electronegative redical 
3. Fe + `CuSO_4` `→``FeSO_4` +Cu`  c. removal of an electronegative redical 
4. `2H_2O` +`4NO_2`+`O_2` `→` `4HNO_3` d.reduction by adding hydrogen
5. 3Fe +`3CI_2` `→` `2FeCI_3` e.electrolysis of water
6. `FeCI_3`+ 3NaOH `→``Fe(OH)_3``↓`+NaCI F.double decomposition,precipitation reaction
7.`2H_2O` `→` `2H_2``↑`+`O_2` e. combination or synthesis reaction

 

Solution

                                    MATCH THE COLUMNS

1 . `H_2` + `CI_2` `→` 2HCI  
e. combination or synthesis reaction

 

2. `2FeCI_3`+ `H_2`  `→` `2FeCI_2` +2HCI`

 

d.reduction by adding hydrogen 

3. Fe + `CuSO_4` `→``FeSO_4` +Cu` 

 

 a. displacement reaction  

4. `2H_2O` +`4NO_2`+`O_2` `→` `4HNO_3`

 

c. removal of an electronegative redical

 

5. 3Fe +`3CI_2` `→` `2FeCI_3`

 

b. addition of an electronegative redical

6. `FeCI_3`+ 3NaOH `→``Fe(OH)_3``↓`+NaCI

F.double decomposition,precipitation reaction

 

7.`2H_2O` `→` `2H_2``↑`+`O_2`

 

e.electrolysis of water
