Question

1. choose all that apply. choose two things that scientists include in chemical formulas. atomic weight the number of atoms in a substance chemical symbols solubility 20. choose all that apply. choose two facts about supersaturated solutions. the solution can hold more dissolved solute than it normally can. supersaturation only occurs under specific conditions. supersaturated solutions change to a dark red or purple color. supersaturation only occurs when pressure is applied to a solution.

Explanation:

Question 19:

Chemical formulas use chemical symbols to represent elements and sub - scripts to show the number of atoms of each element in a substance. Atomic weight is not part of the formula, and solubility is a property not included in the formula.

Question 20:

A supersaturated solution can hold more dissolved solute than normal under specific conditions such as changes in temperature or pressure. There is no general rule that they change to a dark red or purple color, and supersaturation is not only due to pressure application.

Answer:

1. the number of atoms in a substance, chemical symbols
2. The solution can hold more dissolved solute than it normally can, Supersaturation only occurs under specific conditions
