2,1

What is a metalloid?

A mysterious sample is shiny and it will conduct some

electricity but it is not ductile. This is the category of elements that the sample

would best fit in.

What is 3?

This is the chemical formula for acetone, OC(CH3)2. This is the number of Carbon atoms in the

formula for acetone.

What is 2 Nitrogen atoms and 6 Hydrogen atoms?

N2 + 3H2 2NH3

This is the number of and types of atoms in the

reactants of this chemical equation.

What is Potassium?

I went to the local vitamin store to pick up this

supplement, it is signified with the symbol, K.

Compounds are chemically combined and mixtures are physically combined

This is the difference between a compound and a mixture.

3,3

What is a colloid?

The particles in this type of mixture are large enough to scatter light but not heavy

enough to settle out.

What is electrolysis?

This is what it is called when we use electric current to break down a compound.

What is density?

This characteristic property described as the ratio of a samples mass over volume can be used in determining the identity of an element.

What is chemically?

Compounds can only be broken down in this way.

What is concentration?

This describes the amount of solute dissolved in an amount

of solvent.

What are characteristic properties?

Flammability and reactivity are examples of this type of chemical

property that are the same no matter the sample size.

What is magnetism?

Physical Property Substance 1 Substance 2

Boiling Point 1,310°C 1,004°C

Color Silvery white Silvery White

Other Magnetic Non-magnetic

This is how we can tell that substance 1 and 2 are not the same.

What are CH4 and 5O2 (methane and oxygen)?

CH4 + 5O2 CO2 + 2H2O + 302

These are the reactants.

This machine is used to separate mixtures according to their

densities.

What is bubbling, foaming, smell, color change, hot gas formed, or light given off?

These are 3 examples of things that may occur to signify that a

chemical change has taken place.
