What is solubility?

How easily a solid substance dissolves in a liquid

100

What is flammability?

The likelihood of a substance to create an explosion, increase a flame, or even to put out a flame

100
What is density?

The amount of particles in a specific volume

100

Describe what molecule is made of.

Two or more atoms bound or attached together.

100

What is the second most prevalent gas in air?

Oxygen
200

What bath bomb ingredients are INSOLUBLE in water?

coconut oil and olive oil

200

What flammable substances were formed from running electricity through water?

hydrogen and oxygen

200

Which of the bath bomb ingredients are both insoluble in water AND less dense than water?

Olive oil and coconut oil
200

Explain a chemical reaction. Use the terms "atoms and molecules"

A chemical reaction occurs when molecules break apart and atoms rearrange to make a new molecule or substance.


200

What type of gas is most prevalent in air?

nitrogen

300

These bath bomb ingredients dissolve in water

table salt, sugar, epsom salt, baking soda, citric acid
300

Name at least 2 gasses on the some common gasses table will extinguish a flame

argon, carbon dioxide, neon, helium, nitrogen

300

If a gas held in a closed container floats upwards when the cap of the container is opened, what does this mean about the density of the gas?

The gas is LESS dense than air
300

How many TOTAL atoms are in carbon dioxide (regardless of type).

3 atoms - two oxygen and one carbon

300

What gas makes up around 0.04 % of the air and is also found our bodies. 

carbon dioxide gas

400

This solid bath bomb ingredient mixes with water but does not dissolve.

cornstarch

400
What flammable gas on the some common gasses table is used as a heat source to grill food?

propane

400

Name one gas that we studied in class related to the bath bomb experiment that was MORE DENSE than air.

How did we know this gas was more dense than air?

Carbon dioxide because it sank down from the bottle into the container and extinguished a flame.

400
Name all of the atoms found in the baking soda molecule.

Sodium, oxygen, carbon, hydrogen

400

If electrolysis is a reaction involving electricity breaking apart the water molecule into hydrogen and oxygen, 

What is hydrolysis? 

Combining hydrogen and oxygen gas to make water.

500

This bath bomb ingredient was not one of the reactants but was dissolved in the liquid after the reaction.

Sodium citrate

500

What flammable gas on the some common gasses table is a common component of cow burps?

methane

500

What is the law of conservation of matter?

Atoms (matter) cannot be created or destroyed.

500

What is the most prevelant atom in our bodies?

Oxygen
