Choose the incorrect statements.
a) Hydrogen can be placed between Q and S in the reactivity series.
b) Metal R can be extracted by electrolysis.
c) Metal Q is more reactive than metal P
d) Metal S can displace hydrogen from dilute HCI.​

Answer 1

Hydrochloric acid (HCl) reacts readily with most metals other than those in the platinum group in the periodic table. Generally, the metals at the far left of the periodic table react most strongly, and as you progress towards the right side, reactivity lessens
