Which of the following indicate that a chemical reaction has occurred?
the formation of gas bubbles
a change in color
an odor
all of these indicate that a chemical reaction has occurred.
The particles that make up gases are _______________.

very far apart
How are reflectivity and solubility related?
They are both physical properties of matter.

They are both types of mixtures.
You are performing an experiment combining two substances in a closed container. You first pour 350 mL of substance one followed by 430 mL of substance two. A chemical reaction occurs. Choose the equation below that would best explain the total mass of the combined substances.
430 mL - 350 mL = 80 mL
350 mL x 430 mL = 780 mL
350 mL + 430 mL = 780 mL
780 mL - 430 mL = 350 mL

Kenisha wants to raise saltwater fish. She has an aquarium that she previously used to raise freshwater fish. Kenisha wonders, “Does adding salt to freshwater change the weight of the aquarium?” To find out, she plans an investigation using a beaker of water and salt, as shown.
Kenisha follows these steps: 1. Fill a beaker with water until the beaker weighs 50 grams. 2. Weigh out 15 grams of salt. 3. Add the salt from step 2 to the water and stir. 4. Weigh the beaker.
What will happen to the weight of the beaker?
The beaker will weigh less.
The beaker will weigh more because she's adding 15 grams of salt to 50 grams of water.
It will weigh the same because the salt will dissolve in the water.
What is an example of a chemical change?
Tearing paper
Dissolving salt in water
Melting ice
Burning wood
Which of the following is a sign of a chemical reaction?
Cutting a piece of paper
A substance changes color when mixed with vinegar
Dissolving salt in water
Two magnets that stick together
