Proper Disposal Uses pipet - trash can
Reaction mixture - appropriate waste container
Chipped beaker - broken glass box
Used filter paper - trash can
Excess chemical - waste container
Density Formula mass(g)/volume(ml)
Solubility the ability of a solid or gas to dissolve in a liquid
Solvent the solution that does the dissolving
Solute the substance being dissolved
Miscible when two liquids mix completely together
Immiscible when two liquids do not mix together and form layers
Physical Properties - melting point
- boiling point
- color of liquid
Chemical Properties - ability to dissolve metals
- ability to react with oxygen
- ability to dissolve in water
Combinations A + B → AB
two elements come together to form one compound
Decomposition ABC → AB + C
one species decomposes into two or more species
Single Displacement AC + B → A + BC
one element displaces an atom in a compound to form a new compound, while the
displaced atom is converted to its elemental form
Double Displacement AC + BD → AD + BC
the two cations are exchanged and two new compounds are formed
Oxidation-Reduction two half reactions added together, one species loses electrons and the other gains
Actual Yield amount of product recovered in the experiment
