This undergoes both oxidation and reduction. This reaction is
a kind of chemical reaction that includes a transmission of
electrons between two species. An oxidation-reduction reaction is
any chemical reaction in which the oxidation number
of an atom, molecule, or ion fluctuates by attaining or dropping an electron.
Answer: The theoretical yield is 6 rings.
Explanation:
Theoretical yield is predicted or estimated value.
Jeweler used 2 sapphires for 1 ring
Then for each sapphire there will be =
rings are used
For 12 sapphire =
will be used
Out of 10 rings 6 rings with 2 sapphires will be made.
The theoretical yield is 6 rings.
You must first calculate the total weight of 1 mole of the substance. You do this by finding the molar weights on the periodic table of each of the elements in the compound:

So now we take the amount of each element that is given in the compound and divide it by the total mass of the compound:
Carbon: 96.08g

Carbon = 49.48%
Nitrogen: 56.028g

Nitrogen = 28.85%
Oxygen: 31.998g

Oxygen = 16.48%
