Which of the following metal doesn't react even with steam?

Q.

On the basis of the reactivity series of metals, predict how these metals will react with each of the following salt solutions:

Metals: magnesium, zinc, copper, iron, and potassium

Salt solutions: magnesium sulphate, zinc sulphate, copper sulphate, iron sulphate,and potassium sulphate

Q. Which sequence indicates correctly the increasing reactivity of metals?
(a) iron, zinc, magnesium, sodium, potassium
(b) sodium, potassium, magnesium, zinc, iron
(c) magnesium, potassium, sodium, iron, zinc
(d) iron, zinc, sodium, magnesium, potassium

Q. From the metals-copper, iron, magnesium, sodium and zinc-select a different metal in each case which :
(a) does not react with dilute hydrochloric acid.
(b) can form 2⁺ and 3⁺ ions.
(c) has a hydroxide that reacts with both acids and alkalis.
(d) does not react with cold water, but reacts with steam when heated.

Q. Question 7
Metals generally react with dilute acids to produce hydrogen gas. Which one of the following metals does not react with dilute hydrochloric acid?

(a) magnesium
(b) aluminium
(c) iron
(d) copper

Q. Less reactive metals such as magnesium, aluminum, zinc, and iron react with steam to liberate dihydrogen gas.
