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)
