An element is a substance that CANNOT be separated into smaller units of matter via chemical means

• True

• False

A water is considered a compound because

• You cannot separate Oxygen and Hydrogen atoms.

• You can physically separate the hydrogen atoms from the Oxygen.

• You can separate the Oxygen from the Hydrogen, but only by a chemical reaction.

• All of the atoms in the compound have the same number of protons.

Mixtures 

• can be separated chemically

• can be separated physically

• cannot ever be separated

• are very rare on Earth

Gatorade is a homogeneous mixture because 

• Its particles differ from the top to the bottom fo the bottle

• The physical combination of different particles such as sugar and water are spread evenly throughout

• it tastes like it's mixed

• all the atoms are bonded together

Metals can have mixtures too. They are called

• alloys

• allotropes

• bronze

• solutions

If I drop a tablespoon of sand into a bottle of water, the resulting mixture will be 

• homogeneous

• heterogeneous

A sample of matter that can be separated chemically is

• an element

• a compound

• a mixture

A sample of matter that can be separated physically is a(n)

• element

• mixture

• compound
