Question 16

When two substances are combined in a mixture, which of the following is true?

Accepted Answer

Matter is conserved in a solution that has a mass equal to the combined amounts of all original substances.

Answer

Matter is not conserved because a solution will have a greater mass than the original components.

Answer

Matter is conserved in a solution because the solute will have more mass once combined with the solvent.

Answer

Matter is not conserved because a solution will have less mass than the original components.

Question 17

A student is making solutions using the following ingredients:

10 grams of salt, 20 grams of lemon juice, 15 grams of sugar

The solutions she creates are;

Salt and lemon juice with a mass of 30 grams

Sugar and lemon juice with a mass of 35 grams

Which of the following is true?

Accepted Answer

Lemon juice and salt have the same mass before and after combining in a solution.

Answer

A solution of lemon juice and sugar has solid and liquid states of matter.

Answer

Crystal structure in sugar and salt is conserved when solutions are made with lemon juice.

Answer

The mass of the two solutions is identical since they both have the same amount of matter.

Question 18

Which statement best describes the properties of the sand and gravel?

Accepted Answer

The grains of sand are smaller than the gravel.

Answer

The sand grains have the same mass as the gravel.

Answer

Gravel is the same size as the sand grains.

Answer

Each piece of gravel has the same mass.

Question 19

How does the size of the substances in the sand and gravel mixture most likely affect the properties of the mixture?

Accepted Answer

The mixture has larger gravel and small sand grains.

Answer

The mixture only has sand and gravel that are the same sizes.

Answer

The mixture has mostly the largest pieces of gravel and large grains of sand.

Answer

The mixture has mostly small sand grains and just a few smaller gravel pieces.

Question 20

A student mixed varying amounts of baking soda and vinegar in a water bottle and observes the reactions. He finds the total mass of the bottle, balloon, baking soda, and vinegar before and after mixing the substances. Which of the following will be true?

Accepted Answer

The mass of baking soda and vinegar plus the gas produced by the mixture is equal to the original mass in all four trials.

Answer

Trials 2, 3, and 4 will have more mass after mixing because a gas is produced.

Answer

In Trial 1, the final mass will be higher than the other bottles because the vinegar solution creates the fewest bubbles.

Answer

Trial 2 will have less matter after the vinegar and baking soda are combined because foam has less mass than liquid vinegar and solid baking soda.

Question 21

This gas can was left in the sun for 2 hours. Which of the following best explains the change seen in the gas can?

Accepted Answer

An increase in heat changed some of the liquid to a gas. The gas particles expanded to push on the sides of the container.

Answer

The liquid particles increased in amount due to the heat.

Answer

Gas particles were compressed, causing a decrease in volume.

Answer

An increase in heat caused gas to change into a liquid, filling more of the container.

Question 22

What will happen if the lid is removed from the gas can?

Accepted Answer

The pressurized gas particles will rush out of the gas can.

Answer

The gas and liquid particles will rush out of the gas can.

Answer

The particles will remain in place.

Answer

The gas will change back into a liquid.
