Question

Choose the correct answer from the following —
(1) Highly reactive metals mostly occur in carbonates and chloride forms .
(2) Metals like Zn , Al , Pb, Sn are usually form amphoteric oxides
(3) The reaction with which metal react is same for all the metals
(4) Only (1)&(2)
[Please give reason for your answer.]

Answer 1

ANSWER IS OPTION (2)

first one is wrong becauseMetals found in the middle of reactivity series, such as Zn, Fe, Pb, etc. are usually found in the form of oxides, sulphides or carbonates.

Second one is correct because Many metals form Amphoteric oxides like Zinc (Zn), Tin (Sn), Lead (Pb),Aluminum (Al), Beryllium (Be). Even many metalloids also form amphoteric oxide as well as hydroxides. Amphoteric oxides, which is also referred in its another form of Amphoteric molecules includes Amino acids, proteins.

Third is wrong Hydrogen gas is formed as the metal reacts with the acid to form a salt. Many, but not all, metals react with acids. Hydrogen gas is formed as themetal reacts with the acid to form a salt.
