What is Conductivity?"

Question

"Solutions are all around us. While ionic solutions of different strengths are used as conductors, covalent solutions, which contain covalent molecules, and covalent compounds are used as insulators.

Electricity is energy that comes from the movement of charged particles. In this diagram, the electrons in the metal wire move from the positive end of the battery to the negative end. Similarly, in a solution containing ionic compounds, the charged ions move when they're part of a circuit."

Responses

a sugar molecule is made up on non metals and salt is made up on a metal and non metal
a sugar molecule is made up on non metals and salt is made up on a metal and non metal

sugar is a conductor of electricity and salt is a conductor of electricity
sugar is a conductor of electricity and salt is a conductor of electricity

salt is a covalent compound and sugar is a covalent compound
salt is a covalent compound and sugar is a covalent compound

sugar is a covalent compound, salt is an ionic compound

Answer 1

Based on the provided information about conductivity and the nature of ionic and covalent compounds, the correct conclusions you can draw are:

1. A sugar molecule is made up of non-metals and salt is made up of a metal and non-metal. (True)
2. Sugar is a conductor of electricity and salt is a conductor of electricity. (False - sugar is not a conductor while salt is)
3. Salt is a covalent compound and sugar is a covalent compound. (False - sugar is a covalent compound, but salt is an ionic compound)
4. Sugar is a covalent compound, salt is an ionic compound. (True)

So the correct options to select are:

• "A sugar molecule is made up of non-metals and salt is made up of a metal and non-metal."
• "Sugar is a covalent compound, salt is an ionic compound."
