Chemical Reactions
100

This is what happens when a substance breaks apart into pieces to small to see and mixes completely within a liquid.

What is dissolving?

100

These are characteristics of a substance that do not change.

What is a property?

100

Gases, solids, and liquids are all this. 

What is matter?

100

How a substance dissolves in a particular liquid.

What is solubility?

100

These get rearranged in a chemical reaction to create a new substance.

What are the atoms?

200

This is what you call a material when it can dissolve in a particular substance.

What is soluble?

200

How a substance interacts with fire.

What is flammability?

200

Molecules are made of multiple types of these.

What are atoms?

200

This has mass and takes up space.

What is matter?

200

In a chemical reaction the reactants contain CH4 + CO2 + H2O.  Can the products contain CO? 

Yes, both C and O are present in the reactants.

300

This describes a material when it does not dissolve in something else.

What is insoluble?

300

This is the ratio of mass to volume for a given substance.

What is density?

300

This is what happens to the old substances molecules in a chemical reaction.

What is breaking apart and rearranging into new substances?

300

This is what happens when gas/liquids are surround by less dense gas/liquids.

What is sinking?

300

In a chemical reaction the reactants are CH4 + O2.  Can the products contain H2O?

Yes, both H and O are present in the reactants.

400

When something is made of one type of material throughout with uniform properties?

What is a substance?

400

When new substances are made from the atoms/molecules of old substances.

What is a chemical reaction?

400

These cannot be divided or destroyed in chemical reactions or phase changes.

What are atoms?

400

In this system matter can get in or out so the mass can change.

What is an open system?

400

In a chemical reaction the reactants are H2SO4 + CaCO3.  Can the products contain CaN2O6?

No, N is not present in the reactants

500

When something is made during a chemical reaction.

What is a product?

500
The original substances you start with before the chemical reaction occurs.

What are the reactants?

500

In this system no matter can get in or out, so mass stays the same no matter what changes may happen in the system.

What is a closed system?

500

These do not change and can be used to identify substances.

What are properties?

500

In a chemical reaction the reactants are HNO3 + CaCO3.  Can the products contain CaSO4?

No, S is not available in the reactants.
