Moles and Molar Mass.
Molar Mass:
1 mole of Mg: 24g
1 mole of C: 12g
Etc. etc.
No. moles = mass ÷ R.A.M
For example:
Displacement reactions:
A more reactive halogen will displace a less reactive halide from its compounds in solution
Halogen atom = halide ion
Fluorine F = Fluoride F-
Chloride Cl = Chloride C-
Experiment when filled a huge measuring beaker with water and added alkaline, universal indicator and then dry ice:
