Answer:
Sodium is an alkali metal, so it has an electronegativity that is far less than Chlorine. What this means is that Chlorine has a higher tendency to attract electrons from Sodium, which is what defines ionic bonds.
Explanation:
23 because it is the answer
Answer: a) 0.06 M
b) 3.13 grams.
Explanation:
Molarity of a solution is defined as the number of moles of solute dissolved per Liter of the solution.

Moles of 
The balanced reaction for dissociation will be:

Thus for 4 moles of
, there is 1 mole of 
Thus moles of 
Molarity of 
Thus the molarity of the
solution = 0.06 M
b) Mass of
= 
Thus mass of
Wenzhou use is 3.13 grams.
I’m not sure but I think the right is neutral or it’s could be acidic
