Question

.During the reaction of some metals with dilute hydrochloric acid, following
observations were made.
(a) Silver metal does not show any change
(b) The temperature of the reaction mixture rises when aluminium (AI) is added.
(c) The reaction of sodium metal is found to be highly explosive.
(d) Some bubbles of a gas are seen when lead (Pb) is reacted with the acid.
Explain these observations giving suitable reasons.

Answer 1

Answer:

u should know reactivity series.

Step-by-step explanation:

they are

so the silver does not not show any reaction with hydrogen as it is right of hydrogen

as it is good for rising temp the temp is rises

sodium is highly reactive. so,

it will explode.

as there is a displacement reaction bn hydrogen and pb

pb+2hcl--->pbcl2+h2....

here h2 will rise as bubbles .....

hope it helps u....

plz mark as branliest... plz mark
