When metal X is treated with a dilute acid Y,then a gas Z is evolved which burns Readily by making a little explosion

1) Name any two metal which can behave like metal X.
2) Name any two Acid which can behave like acid Y
3) Name the gas Z
4) Is the gas Z lighter than or heavier than air
5) Is the reaction between Metal X and acid Y exothermic or endothermic my 6) By taking a specific example of metal X and dilute acid Y,write a balanced chemical equation for the reaction which take place. Also indicate physical state of all the reactants and products

Howdy!!

your answer is ---

1) the metals are -
• sodium (Na)
• Zinc (Zn)
-------------------------

2) the acids are --
• Hydrochloric acid (HCl)
• Sulphuric acid (H2SO4)
-------------------------

3) the gas Z is Hydrogen (H2)
-----------------------

4) the gas Z is lighter than air
-----------------------

5) the reaction between Metal X and acid Y is exothermic .
-----------------------

6) Examples are --

•2Na(s) + 2HCl(aq) ===> 2NaCl(s) + H2(g)

• Ca(s)+ 2HCl(aq) ==> CaCl2(s) + H2(g)

Answer:1)metal x can be sodium,potassium,zinc.

2)acid y can be hydrochloric acid,sulphuric acid

3)gas z is hydrogen

4)gas z is lighter than air

5)reaction is exothermic

6)example:

2Na(s)+2HCl(aq)--->2NaCl(s)+H2(g)
