A) Mass Number
B) Protons and Electrons
C) (I think group but I'm not 100% sure on this...)
D) 12 (To work out the number of neutrons you do MASS number - ATOMIC number aka the number of protons so in this case you'd do 23-11=12)
Hope this helps

Answer:</h3>
2NaOH(aq) + CaCl₂(aq) → 2NaCl(aq) + Ca(OH)₂(s)
<h3>
Explanation:</h3>
- The equation for the reaction between calcium chloride and sodium hydroxide to form calcium hydroxide and aqueous sodium chloride is given by;
2NaOH(aq) + CaCl₂(aq) → 2NaCl(aq) + Ca(OH)₂(s)
- It is an example of precipitation reaction in which a precipitate is formed as one of the products.
- During precipitation two aqueous solution combine to form a insoluble salt and a soluble salt.
Mass number=number of protons+number of neutrons
=atomic number+number of neutrons
