Explanation :
Combination reaction : It is a type pf reaction in which the two or more molecules combine to form a larger single molecule as a product.
Decomposition reaction : It is a type of reaction in which a single larger compound decomposes to give two or more smaller molecules as a product.
Combustion reaction : It is a type of reaction in which a hydrocarbon molecule react with the oxygen molecule to give carbon dioxide and and water as a product.

Answer:
Concentration of = 0.03101 M
Concentration of = 0.03721 M
Explanation:
A)
The reduction for is;
6 moles of = 1 mole of
number of moles of Cu reacted =
number of moles of Cu reacted =
number of moles of Cu reacted = 0.00747 mole
number of moles of reacted =
number of moles of reacted = 0.001245 mole
Concentration of =
Given that the volume = 40.15 mL = ; we have:
Concentration of =
Concentration of = 0.03101 M
B)
The reduction for is;
5 moles of = 1 mole of
number of moles of Cu reacted =
number of moles of Cu reacted =
number of moles of Cu reacted = 0.00747 mole
number of moles of reacted =
number of moles of reacted = 0.001494 mole
Concentration of =
Given that the volume = 40.15 mL = ; we have:
Concentration of =
Concentration of = 0.03721 M
