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.
b)
Name any two acids which can behave like acid Y.
c)
Name the gas Z.
d)
Is the gas Z lighter than or heavier than air?
e)
is the reaction exothermic or endothermic?
f)
By taking a specific example of metal X and acid Y write a balanced chemical equation
for the reaction. Also indicate the physical states of reactants and products.

Answer 1

Hi there,

☆ X metals as Na , K

☆Y acids as HCl , HBr

☆ The equation

2Na(s) + 2HCl (aq) = 2NaCl (aq) +

H2 (g)

☆ Z is hydrogen gas

☆ Hydrogen gas is lighter than air

☆ The reaction is exothermic process with large amount of energy causing H gas explosion
