The atoms of chlorine are held together by non-polar covalent bonds. Covalent bonds are formed between two or more atoms having zero or very small electronegativity difference. For homonuclear molecules where the two bonding atom are of the same kind, the electronegativity difference is zero.
A controlled experiment is one in which evrerything is held constant except for one verieble, maybe is usually a st of data is taken for a control group.
Answer:
True
Explanation:
Ionic bonds are formed by complete transfer of electronic from one to another atoms. The metals are electron donor and non metal are the electron accepter.
Consider the example of sodium chloride. Sodium is metal and chlorine is non metal. Sodium is present in group one and have one valence electron. It loses one electron and get stable electronic configuration.
While chlorine is present in group 7A and have seven valence electron. It require one more electron to complete the octet. Thus hen sodium and chlorine the electron lose by sodium is accepted by chlorine and form ionic compound.
The compound having ionic bonds generally have moderate to high boiling points and melting point because of greater electrostatic interaction. Their electrical conductivity are high and these minerals tend to dissolve in water.
Stirring affects how quickly a solute dissolves in a solvent, but has no effect on how much solute will dissolve. The amount of solute that will dissolve is affected by temperature - more will dissolve at higher temperatures. This is called the solubility of the solute

a risk to human health or the environment arising from biological work, especially with microorganisms.
