Determine what redox reaction, if any, occurs (at 25°C) when tin metal (Sn) is added to (a) a 1.0 M solution of NiCl, and (b) a 1.0 M solution of HCl. (a) Sn is added to a 1.0 M solution of NiCl2 o o O O Sn(s) + Ni2+(aq) → Sn2+(aq) + Ni(s) Sn2+(aq) + 2C1(aq) → Sn(s) + Cl2(8) Ni2+(aq) + 2CI+ (aq) → Ni(s) + Cl2@) No reaction. (b) Sn is added to a 1.0 M solution of...

Explain why the highest oxidation state for group 14 (IVA), +4, is exclusively observed for carbon but hard to stabilize for lead, which has +2 as its most stable oxidation state. When formulating your answer, also consider what oxidation states are typically exhibited by silicon, germanium and tin.
The element tin often occurs in nature as the oxide, SnO2. In order to produce pure tin metal from this sort of tin ore, the ore is usually heated with coal (carbon). This produces pure molten tin, with the carbon being removed from the reaction system as the gaseous byproduct carbon monoxide. The correct chemical equation for this process is: SnO2(s) + C(s) + heat --> Sn(s) + CO(g) SnO2(s) + C(s) + heat --> Sn(1) + CO(g) SnO2(s) +...
