Two statements about metals are given.
1 Metals contain a lattice of negative ions in a ‘sea of electrons’.
2 The electrical conductivity of metals is related to the mobility of the electrons in the structure.
Which is correct?
A Both statements are correct and statement 1 explains statement 2.
B Both statements are correct but statement 1 does not explain statement 2.

Powdered calcium carbonate reacts with dilute hydochloric acid to produce calcium chloride, water and carbon dioxide.
What is the correct ionic equation, including state symbols, for this reaction?
CaCO3(s) + 2HCl(aq) → CaCl2(aq) + H2O(l) + CO2(g)
Ca2+(aq) + CO32–(aq) + 2H+(aq) → Ca2+(aq) + H2O(l) + O2(g)
CO32–(aq) + 2H+(aq) → H2O(l) + CO2(g)
CaCO3(s) + 2H+(aq) → Ca2+(aq) + H2O(l) + CO2(g)
Metal M is displaced from aqueous M nitrate by copper.
Which statement about metal M and its compounds is correct?
M carbonate is stable when heated.
M oxide is reduced to M by heating with carbon.
M reacts with dilute hydrochloric acid to give hydrogen.
M reduces zinc oxide to zinc on heating.
