4 sig fig in that expression
MgqI% = the formula and mass for H20 and that should be your answer for water
Answer:
A) An ionic compound dissolved in a polar solvent
Explanation:
Potassium Chloride's chemical formula is KCl. Most ionic compounds are formed between a nonmetal and a metal. In this case, potassium is acting as the metal and chloride is the nonmetal. Water is a polar solvent due to the electronegativity of the oxygen in the molecule creating a partial negative pole, leaving the hydrogen atoms partially positive. Hence, A is your best answer.
