Answer:
Explanation:
The products of this reaction are given by:
Firstly, dichromate anion becomes chromium(III) cation, let's write this change:
The following steps should be taken:
- balance the main element, chromium: multiply the right side by 2 to get 2 chromium species on both side:
- balance oxygen atoms by adding 7 water molecules on the right:
- balance the hydrogen atoms by adding 14 protons on the left:
- balance the charge (the total net charge on the left is 12+, on the right we have 6+, so 6 electrons are needed on the left):
Similarly, tin(II) cation becomes tin(IV) cation:
Now that we have the two half-equations, multiply the second one by 3, so that it also has 6 electrons that will be cancelled out upon addition of the two half-equations:
Add them together:

Answer: C) Either benzene or oxygen may limit the amount of product that can be formed
Explanation: Benzene and oxygen are the reactants of the equation. What type and the amount of reactants there are in a chemical reaction affects the outcome. Therefore, seeing as benzene and oxygen are the reactants, the answer is C).
