Solubility
What is solubility?
How easily a solid substance dissolves in a liquid
What is flammability?
The likelihood of a substance to create an explosion, increase a flame, or even to put out a flame
The amount of particles in a specific volume
Describe what molecule is made of.
Two or more atoms bound or attached together.
What is the second most prevalent gas in air?
What bath bomb ingredients are INSOLUBLE in water?
coconut oil and olive oil
What flammable substances were formed from running electricity through water?
hydrogen and oxygen
Which of the bath bomb ingredients are both insoluble in water AND less dense than water?
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.
What type of gas is most prevalent in air?
nitrogen
These bath bomb ingredients dissolve in water
Name at least 2 gasses on the some common gasses table will extinguish a flame
argon, carbon dioxide, neon, helium, nitrogen
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?
How many TOTAL atoms are in carbon dioxide (regardless of type).
3 atoms - two oxygen and one carbon
What gas makes up around 0.04 % of the air and is also found our bodies.
carbon dioxide gas
This solid bath bomb ingredient mixes with water but does not dissolve.
cornstarch
propane
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.
Sodium, oxygen, carbon, hydrogen
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.
This bath bomb ingredient was not one of the reactants but was dissolved in the liquid after the reaction.
Sodium citrate
What flammable gas on the some common gasses table is a common component of cow burps?
methane
Name a gas that is less dense than air and is used in advertising (store signs).
Neon
What is the law of conservation of matter?
Atoms (matter) cannot be created or destroyed.
What is the most prevelant atom in our bodies?
Oxygen
