<span>Since the answer is in grams, kilograms must first be converted to grams. A kilogram is equivalent to 1000 grams. Therefore, multiply 1.2 kilograms by 1000 and you get 1,200 grams. Then, calculate the number of hours in 5 days. Each day is 24 hours and 24 hours multiplied by 5 days equals 120 hours. Lastly, since the answer is in grams per hour, divide 1,200 grams by 120 hours and the resultant rate of reaction is 10 g/hr.</span>

Potassium chloride dissolved in pure water is an
postnew [5]

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.
