Covalent compounds are compounds that share electrons. They tend to have properties like lower melting points and lower conductivity.
For an aqueous solution to conduct electricity, ions must be
present in solution.
This means soluble salts will conduct electricity. Also,
since acids and bases have ions in solution, they could also conduct electricity.
Option 1 is a soluble salt. Options 2 and 4 are base and acid respectively.
Option 3, though soluble in water, exist as a molecule, therefore its solution
cannot conduct electricity.
A catalyst is a substance that increases the rate of a chemical reaction by lowering the activation energy without being used up in the reaction. After the reaction occurs, a catalyst returns to its original state and so catalysts can be used over and over again.
A cell is NOT part of an atom.... Protons have a positive charge, electrons have a negative charge, and neutrons have no charge, they are in atoms, but a CELL is NOT
