What would the carbon dioxide part of a soft drink be classified as?A. solute
B. solvent
C. solution
D. mixture

Answers

Answer 1

Answer:

Answer is: A. solute .

Solvation is the interaction of solvent (in this example water) with molecules or ions (in this example carbon dioxide)) in a solute.

Solvent (usually a liquid, but can also be a solid or a gas) is a substance that dissolves a solute (dissolved in the solvent).

Solvent is always the same state of matter as the solution. In this example, soft drink is a liquid, so water is a solvent.

Answer 2

Answer: Answer: A. Solute
Solute is what is mixed into the solvent

How many grams of KNO3 would recrystallize from 100 g of water, if a saturated solution were cooled from 50 degrees celcius to 20 degrees celcius?

Answers

Answer:

$m_(cryst)=58g$

Explanation:

Hello there!

In this case, according to the attached solubility chart, it is possible for us to realize that about 88 grams of KNO3 are soluble at 50 °C but just 30 grams are soluble at 20 °C in the same 100 g of water.

In such a way, the crystalized mass of this solute can be calculated by subtracting the mass at 50 °C and the mass at 20 °C:

$m_(cryst)=88g-30g\n\nm_(cryst)=58g$

A sample of CO2(s) and a sample of CO2(g) differ in their1) chemical compositions
2) empirical formulas
3) molecular structures
4) physical properties

Answers

The correct answer is D.
CO2(s) is a solid.
CO2(g) means it is gas.

So they differ in their physical properties.
Physical propertiers means that they differ in their look.

A sample of aluminum metal absorbs 8.32 J of heat, upon which the temperature of the sample increases from 23.2 degrees C to 30.5 degrees C. Since the specific heat capacity of aluminum is 0.90 J/g-K, the mass of the sample is what in grams?

Answers

Given:

8.32 J of heat

from 23.2 degrees C to 30.5 degrees C

heat capacity of aluminum is 0.90 J/g-K

Required:

m in grams

Solution:

H = mCpT

(8.32 J) = m(0.90 J/g-K)(30.5 – 23.2)K

m = 1.27g
