Percent yield is 108.3%
<u>Explanation:</u>
Percent yield is the ratio of experimental yield and the theoretical yield multiplied by 100.The expression for the percent yield is given as,
Percent yield =
It is given that the experimental or actual yield is 3.9 g and the theoretical yield calculated using stoichiometry is 3.6 g, then the percent yield is calculated as,
Percent yield =
So the percent yield is 108.3%.
Answer:
2 Na atoms
1 C atom
3 O atoms
gram formula weight = 105.99 g

It looks like they have the same effect as divers. Because of fear, whales rise up too quickly causing gas bubbles to enter they blood vessels and causing small gashes in their bones as well.
atomic number = number of protons
number of protons = number of electrons
So, number of electrons = 5
So, electron configuration = 2, 3
So, its valency = 3
