Mixtures, Solutions, Chemical change

Is mae of two or more substances that are together in the same place, but their atoms are not chemically combined.

• Mixture

• Soluble

• Solven

There are two types of mixtures:

• Homogeneous

• Colloid

• Heterogeneous

Is a heterogenous mixture containing small, undissolved particles that do not separate or settle out if the mixture is undisturbed.

• Suspension

• Colloid

• Homogeneous

Is a mixture with particles that can be seen and easily separated by settling or filtration.

• Suspension

• Colloid

• Solvent

Is a homogeneous mixture of a solvent and one or more solutes.

• True

• False

NaCl is an _______________________

Are properties that affect solubility

• Temperature

• Pressure

• Density

A change that alters the form of appearance of a substance without changing it into a different substance.

• Physical change

• Chemical change

• Chemical reaction

Chemicals that undergo chemical changes

• reactants

• products

• solubility

Are indicators that a chemical reaction has occured:

• color change

• gas production

• formation of a precipitate

• change in sound

• change in texture
