An element X and compound YZ react separately with acid as shown.
X(s) + 2H+(aq) → X2+(aq) + H2(g) YZ(s) + 2H+(aq) → Y2+(aq) + H2Z(g)
When 1.0 g of either X or YZ is reacted with an excess of acid, the total volume of gas formed is
reacted with an excess of acid, the total volume of gas formed is the same.
Which statements are correct?
1 Ar(X) = Mr(YZ)
2 X and Y are metals.
3 X and Y must both be in the same Group of the Periodic Table.
