Question

7 Magnesium chloride may be prepared by reacting magnesium
with dilute hydrochloric acid.
A sample of magnesium of mass 1.215 g was added
to 60.0 cm dilute hydrochloric acid of concentration
2.00 mol dm-
The equation for the reaction is
Mg(s) + 2HCl(aq) – MgCl2(aq) + H2(g)
(a) State two observations that are made when magnesium
reacts with dilute hydrochloric acid.
[2]
(b) (i) Calculate the amount, in moles, of magnesium
used
(ii) Calculate the amount, in moles, of hydrochloric
acid used.
(iii) Use your answers to (b)(i) and (b)(ii) to show that the
hydrochloric acid is in excess.
[2]
(c) Calculate the volume, measured at rt.p. of hydrogen
produced in this reaction.
(The molar volume of hydrogen at rt.p. is 24 dmº mol-?) [2]
