Decreases
Explanation:
The molecules lose potential energy during chemical reactions.
In a chemical reactions, bonds are broken for new ones to be formed. The process of breaking and forming bonds diminishes the potential energy of a bond.
Potential energy is the energy at rest in a body.
In chemicals, potential energy is constituted by the chemical energy stored within the bonds.
When chemical reactions occur, the energy is released often in the form of heat energy. There is always a decrease in potential energy when chemicals reacts together.

Covalent bonds
Explanation:
Covalent bonds are formed between two atoms having low or zero electronegativity difference.
This bond type is usually found in the molecules of non-metals.
Properties:
- They are usually gases or volatile liquids or low melting point solids.
- Most of them are usually insoluble in polar solvents.
- They are mainly non-conductors of electric current.
- Their reactions are generally slow.

<u>Answer:</u> The molarity of anions in the solution is 0.0316 M
<u>Explanation:</u>
To calculate the molarity of solution, we use the equation:
We are given:
Given mass of iron (II) chloride = 0.10 g
Molar mass of iron (II) chloride = 126.75 g/mol
Volume of solution = 50 mL
Putting values in above equation, we get:
1 mole of iron (II) chloride produces 1 mole of ions and 2 moles of ions
So, concentration of chloride ions (anions) in the solution =
Hence, the molarity of anions in the solution is 0.0316 M
