F. Sodium bisulfate: NaHSO4
Explanation:
All are ionic salts with different valent (mono valent cation or poly valent cation and anions) ions.
Answer:
C) Covalent bonds come about because of a sharing of electrons; ionic bonds do not.
Explanation:
There are two main types of chemical bonds- covalent and ionic/electrovalent bonds.
Ionic bond: Ionic or electrovalent bonds are characterized by the transfer of electrons from electropositive atoms (metals) to electronegative atoms (non-metals). The metal atoms after donating their electrons become positively charged ions (cations) while the non-metal atoms after accepting electrons become negatively charged ions (anions). Strong electrostatic forces of attraction constitutes ionic bonds.
Covalent bond: Covalent bonds are formed by the sharing of electrons by the atoms involved in the bond; usually between atoms of comparable electronegativities or atoms of the same element. The shared electrons are contributed by each of the atoms involved in the bonding or may be contributed by only one of the atoms. In covalent bonding, molecules rather than ions are formed.
If you have a concern about fluoride in your drinking water, you can get more information by contacting the local community water system and is denoted as option D.
<h3>What is Water?</h3>
This is referred to as a universal solvent and is usually colorless and used for various purposes such as drinking, washing etc.
Fluoride is added to water by the the community water system as it helkps to build strong teeth and cavities thereby preventing tooth decay. They know the concentration which is added to the water which is why they need to be contacted for more information.

The question is incomplete, here is the complete question:
There are two steps in the usual industrial preparation of acrylic acid, the immediate precursor of several useful plastics. In the first step, calcium carbide and water react to form acetylene and calcium hydroxide:
In the second step, acetylene, carbon dioxide and water react to form acrylic acid:
Write the net chemical equation for the production of acrylic acid from calcium carbide, water and carbon dioxide. Be sure your equation is balanced.
<u>Answer:</u> The net chemical equation is written below.
<u>Explanation:</u>
The intermediate balanced chemical reaction are:
(1) ( × 6 )
(2)
To omit acetylene from the net chemical reaction, we multiply Equation (1) by 6.
<u>Equation 1:</u> 
<u>Equation 2:</u>
<u>Net chemical equation:</u> 
Hence, the net chemical equation is written above.
