This answer is false because if you have a field that runs off into a lake all of the manure and chemicals from that field gets into the soil and in return runs off into the water.<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.

If I helped, a brainliest would be greatly appreciated!

The empirical formula of a group of compounds is CHCl. Lindane, a powerful insecticide, is a member of this group. The molar mas
Sergeeva-Olga [200]

Answer:

<h2>D) 6</h2>

Explanation:

since,   n = molar mass / empirical formula mass

   Empirical formula mass = Total mass of atoms present in empirical formula

                       CHCl = 12+1+35.5

                                = 48.5

 Given, Molar mass = 290.8 g.

           So,        n = 290.8/48.5

                           = 5.995 , that is approx  6.

        So, Molecular formula = n × Empirical formula

                                           = 6 × CHCl

                                           = C_{6}H_{6}Cl_{6}

       So,   Number of C = 6
