Answer:
Explanation: The molar mass and molecular weight of Cr2(SO3)3 is 344.182.
Oxidation
It is oxidation because two O's 1 x 1 d 2 i's 1 n and 1 a
Answer:
c) +2 to 0
Explanation:
SO4 has a charge of -2, so the Cu attached to that has to be a +2 since the polyatomic molecule has no overall charge
Cu(s) is a solid metal and they have no charge, therefore it is zero
Copper undergoes Oxidation (gain of electrons)
Answer:
d. reducing agent
Explanation:
Na acts as a reducing agent. A reducing agent is a substance whose function is to reduce or donate electrons to another, and by doing so it becomes oxidized. We can see the mechanism of the reaction in the image attached below.
Answer is 13.668! Or in scientific notation it would be .13668 x 10^2
