Question

EXERCISE S
1. Which of the following pairs will give displacement reactions
(a) NaCl solution and copper metal
(b) MgCl, solution and aluminium metal
(c) Feso, solution and silver metal
(d) AgNO, solution and copper metal.
ich of the follou
Which​

Answer 1

Answer:

According to the reactivity series of metals, copper metal is less reactive than sodium metal. Hence, no displacement reaction will occur between NaCl solution and copper metal. Again, aluminium metal is less reactive than Mg, so no displacement reaction will occur between MgCl₂ solution and aluminium metal

Explanation:

hope it's useful mark me as Brainliest and give thanks also.

Answer 2

Answer:

d) AgNO^ solution and copper metal

AGNo 3 Solution & copper metal

Copper metal and silver nitrate solution gives displacement reaction and the chemical equation can be written as:

$Cu+2AgNo_3→cu(No_3)_2+2Ag$
