Answer:
a) False
b) False
c) True
Explanation:
a) Most sulfur oxides formed during combustion come from sulfur in the air: The sulfur burns in presence of oxygen to produce sulfur oxides, the source of sulfur is anthropogenic activities (Human activities).
So the given statement is false.
b) A flue gas scrubber removes SO2 pollution in a coal-fired power plant by using lime to convert the SO2 into alcohols:
False
The lime reacts with sulfur dioxide to give carbon dioxide and calcium sulfite.
c) True
c)
Answer:
Dilution is the prosess where a solution is added more of the solvent to decrease the concentration of the solute. In dilution, the amount of solute does not change, the number of moles are the same before and after dilution.
The second statment is true and right. Hope this helps!!
Answer: 
, product favoured
Explanation:
Complete ionic equation : In complete ionic equation, all the substance that are strong electrolyte and present in an aqueous are represented in the form of ions.
Net ionic equation : In the net ionic equations, we do not include the spectator ions in the equations.
When hydrochloric acid react with potassium cyanide, then it gives potassium chloride and hydrocyanic acid as products.
The complete ionic equation will be:
The net ionic equation will not contain spectator ions which are 
and 
:
The reaction is product favoured.
