Chemical Reactions
What is the effect of mixing two substances with water?
Chemical Reaction
What is the effect of mixing all three substances in a bag with water?
Gas, so much so that it popped
These three substances were used in our experiments
Calcium Chloride, Baking Soda, and Citric Acid
This is how you know a mixture is a solution.
Dissolves and the solution is clear.
Two or more substances combined make this.
Mixture
This causes fizzing in a liquid
Gas
In your car, a checmical reaction occurs in this object to create enough gas to protect you in a crash
Air Bag
What substance was formed from the Calcium Choride/Baking Soda mixture?
Calcium Carbonate, or chalk
Between the Calcium Chloride/Baking Soda mixture & the Citric Acid/Baking Soda mixture, this one produced more gas
Citric Acid/Baking Soda
How can a mixture be separated?
With screens, filters, and funnels
This gas is formed when calcium cholride and baking soda are mixed
CO2, or Carbon Dioxide
This cone shaped mountain is a favorite for Science Fair presentations
Volcano
If something dissolves completely into a liquid it is said to be this.
Soluble
What happens when you mix sibstances in a bag with water?
Depending on the substances, gas is produced, and precipitates form
A change from a solid to a liquid is known as this
Melting
This is produced by a chemical reaction.
Product
If I wanted a bottle rocket to fly, what two materials could I combine inside before capping it & running away?
baking soda and vinegar
When something doesn't dissolve completely into a liquid, it is said to be this
Insoluble
An effect, or material that can cause changes to experiments is known as the...
variable
A change from a liquid to a solid is known as this
freezing
This is a new substance created from a chemical reaction that settles out of a liquid
Precipitate
When apple juice goes bad, this chemical change happens before the bottle finally explodes.
fermentation
When a chemical reaction begins and ends with the same mass, we call this
The Law of Conservation
If matter changes its shape, color, or temperature it is known as this type of change
