Question

read the following statement carefully, and select the correct statements about the physical and chemical properties of metal
(i) all metals are ductile.
(ii) generally, metals are ductile.
(iii)metals which are more reactive than hydrogen react with acids to release hydrogen gas.
(iv) all metals react with acids to release hydrogen gas.

The correct statement is / are

(a) (i) and (ii)
(b) (i) and (iii)
(c)(ii) and (iii)
(d)(ii) and (iv)

Please answer with explanation

Answer 1

Answer:

the correct option is option [a]

Answer 2

The correct statement among the ones given above is is option 2 and option 3.

The answer is option c.

Explanation:

• most metals are usually ductile. This means that they can be drawn into thin wire should study in addition to this day have different range of reactivity.

• As a result of these those metals which are above hydrogen in the metal reactivity series can react with dilute acid to give hydrogen. However elements like copper are below hydrogen and hence cannot react with acid to give hydrogen.
