Answer:
It's all about understanding the concept, see my explanation.
Explanation:
A ionic bond is formed between a metal element and a non metal element always. On the other hand, a molecular bond or covalent bond is formed between 2 elements which are both non metals. A ionic bond is made when there is a electron transfer occurring meaning that one element is giving it's electron to another to ethier become a postive or negative ion. Whereas a molecular bond is made when two non metals elements share there electrons.
• An example of a ionic bond would be MgCl2 as we know magnesium is a metal and chlorine is a non metal.
• An example of a molecular bond would be NF
which we know are both non metals.

The complete equation to following equation to make a double replacement reaction is: Na2SO4 + BaCl2 = BaSO4 + 2NaCl.
<h3>What is a double displacement reaction.</h3>
A double displacement reaction is the reaction that involves the replacement of two elements.
According to this question, barium sulfate (BaSO4) and sodium chloride are produced from the chemical equation given.
This clearly suggests that Sodium sulfate is the missing reactant, hence, the complete equation to following equation to make a double replacement reaction is:
Na2SO4 + BaCl2 = BaSO4 + 2NaCl.

<span>n = c x v
= 1 x 0.025
= 0.025 moles
= n
NaOH = n/v
= 0.025/0.045
= 0.56M
So is it A
