Question

When metal X is treated with a dilute acid Y, then a gas Z is evolved which burns readily by making a little explosion.
a) Name any two metals which can behave like metal X.

Answer 1

Answer:

Na, k

Explanation:

sodium and potassium are very reactive metals

Answer 2

Hey mate!

We can consider potassium, sodium or lithium as metals that behave like X.

Explanation:

since an explosion is observed in the reaction, it is a vigorous reaction. We know that any metal reacting with acid will form salt of respective metal and liberate hydrogen. High reactive metals like sodium reacts vigorously with acids. Hence any high reactive element can be considered as answer. (I group of periodic table)

Hope this answer helps...
