question 1 (1 point) saved
in water, a substance that partially ionizes in solution is called a
nonelectrolyte.
semiconductor.
weak electrolyte.
strong electrolyte.
nonconductor.
question 2 (1 point) saved
the mass percent concentration refers to
grams of solute in 1 kg of solution.
grams of solute in 1 kg of solvent.
grams of solute in 100 g of solution.
grams of solvent in 100 g of solution.
grams of solute in 100 g of solvent.

Explanation:

• Question 1:
• A nonelectrolyte does not ionize in solution.
• A semiconductor is a material with electrical conductivity between a conductor and an insulator (not relevant to ionization in solution).
• A weak electrolyte partially ionizes in solution.
• A strong electrolyte completely ionizes in solution.
• A nonconductor does not conduct electricity (not relevant to ionization in solution).
• Question 2:
• Mass - percent concentration is defined as \(\text{Mass}\%=\frac{\text{Mass of solute}}{\text{Mass of solution}}\times100\%\). So it is grams of solute in 100 g of solution.

Answer:

• Question 1: C. weak electrolyte
• Question 2: C. grams of solute in 100 g of solution
