"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.

Question

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."

sugar is a covalent compound, salt is an ionic compound
sugar is a covalent compound, salt is an ionic compound

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

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

Answer 1

Based on the information provided, the correct responses would be:

1. sugar is a covalent compound, salt is an ionic compound
2. a sugar molecule is made up of nonmetals and salt is made up of a metal and nonmetal

The first statement accurately describes the nature of sugar (a covalent compound) and salt (an ionic compound). The third statement also correctly identifies the composition of sugar and salt, with sugar composed of nonmetals, and salt comprising a metal (like sodium) and a nonmetal (like chlorine).

The last option, sugar is a conductor of electricity and salt is a conductor of electricity, is not correct. Sugar does not conduct electricity, as it doesn't dissociate into ions in solution, whereas salt, being ionic, does allow for the conduction of electricity when dissolved in water.
