A) True — in a water molecule the oxygen carries a partial negative charge and the hydrogens carry partial positive charges.
B) Select:
- most likely will conduct electricity
- separates into ions
Explanation: NaCl is an ionic compound; in water it dissociates into Na+ and Cl− ions, and those free ions allow the solution to conduct electricity.
B) Select:
- most likely will conduct electricity
- separates into ions
