Hello there!
In this case, for the required chemical reactions, we proceed as follows, by considering that the left-handed elements stand for the cations and the right-handed ones for the anions:
1:
1. 
2. 
3. 
2: In this case, we can represent the formula equation first according to the neutralization reaction:
Which is worded as: three molecules of aqueous sodium hydroxide reacts with one molecule of aqueous phosphoric acid to yield one molecule of aqueous sodium chloride and three molecules of liquid water.

Answer:
4.Electronic configuration
Explanation:
The number of digits in the electronic configuration tells you how many shells are in an atom.
<u>Answer:</u> The molality of 
solution is 4.013 m
<u>Explanation:</u>
Molality is defined as the amount of solute expressed in the number of moles present per kilogram of solvent. The units of molarity are mol/kg.
The formula used to calculate molarity:
.....(1)
Given values:
Given mass of = 20.0 g
Molar mass of = 62.3 g/mol
Mass of solvent = 80.0 g
Putting values in equation 1, we get:
Hence, the molality of solution is 4.013 m
Time such as minutes, days, and months will always be a(n)....... INDEPENDENT variable
The symbol used to indicate a substance is (aq).
