Chemistry : Chemical Reactions 1
Overview
Students will build upon the fundamentals learnt in PACE and see how chemical reactions occur between reactants to form new products. They will be introduced to the basics of quantitative chemistry with the conservation of mass law, and investigate key reaction types including: combustion, oxidation and thermal decompositions.
The main SMSC/Personal Development content of this topic includes: PD2 – developing mutual respect / tolerance (practical work), PD15 – Sense of enjoyment and fascination, PD17 – reflecting on experiences and PD22 – working and socialising with other students.
The main UN Rights of a Child covered are No.13 – Sharing thoughts freely and No.28 – Access to Education.
Example Key Words
Combustion
Combustion is the scientific word for burning.
Oxidation
Oxidation is the loss of electrons during a reaction by a molecule, atom or ion.
Displacement
When a more reactive metal will displace a less reactive metal from its compounds.
Neutralisation
This is a chemical reaction in which acid and an alkali react with each other to form a neutral solution.
PH
pH is a measure of how acidic/basic a solution is, on a scale from 0 -14.
Acid
An acid is any substance that in water solution changes blue litmus paper to red, reacts with some metals to release hydrogen and reacts with bases to form salts.
