Physical Science Exam 3

what is matter?

• anything that has mass/occupies space

• pure substance that contains more than one type of element bonded to in fixed proportions

• substance that only contains one kind of atom and cannot be broken down any further through chemical reactions

• chemical reactions that occur in living organisms

which is pure substance (form of matter)?

• matter whose composition does not change from one sample to another

• substance that have differing composition and so varying properties

which is mixtures (form of matter)?

• matter whose composition does not change from one sample to another

• substance that have differing composition and so varying properties

what is a Solvent Solution?

• substance dissolved in solvent

• liquid or substance in the larger quantity

• solution in which water is solvent

• more solute can be dissolved in the solution at the same temp.

what is a Solute Solution?

• substance dissolved in solvent

• liquid or substance in the larger quantity

• solution in which water is solvent

• more solute can be dissolved in the solution at the same temp.

what is an Aqueous Solution (aq)?

• maximum amount of solute is dissolved in the solvent

• liquid or substance in the larger quantity

• solution in which water is solvent

• more solute can be dissolved in the solution at the same temp.

what is an Unsaturated Solution?

• maximum amount of solute is dissolved in the solvent

• liquid or substance in the larger quantity

• solution in which water is solvent

• more solute can be dissolved in the solution at the same temp.

what is an Saturated Solution?

• maximum amount of solute is dissolved in the solvent

• contains more than the normal maximum amount of dissolved solute at the given temp.

• solution in which water is solvent

• more solute can be dissolved in the solution at the same temp.

what is an Supersaturated Solution?

• maximum amount of solute is dissolved in the solvent

• contains more than the normal maximum amount of dissolved solute at the given temp.

• solution in which water is solvent

• more solute can be dissolved in the solution at the same temp.

What is Metals in the Periodic Table?

• good conductors of electricity/heat, 75 metals in table (solid)

• brittle, dull, poor conductors of heat/electricity (gas)

• properties between metals and nonmetals
