Answer: 6 moles of NaCl are produced when 2 moles of sodium phosphate reacts with 3 moles of calcium chloride
Explanation:
The balanced chemical equation is:
According to stoichiometry :
2 moles of
require 3 moles of
Thus both are limiting reagent as both will limit the formation of product.
As 2 moles of
reacts with 3 moles of
give = 6 moles of 
Thus 6 moles of NaCl are produced when 2 moles of sodium phosphate reacts with 3 moles of calcium chloride
C) the number of the pricipal energy level containing the outer electrons increases
Answer:

Explanation:
Hello,
In this case, the undergone chemical reaction is:

In such a way, the acidic redox balance turns out:

Which leads to the total balanced equation as follows:

Thus, as the mass of oxalic acid is not given, one could suppose a value of 1 g (which you can modify based on the actual statement) in order to compute the oxalic acid moles as shwon below:

Whereby the molality results:

Remember you can modify the oxalic acid mass as you desire.
Best regards.
