Aqa Ks4 Gcse Chemistry Science Chemical Changes Revisio Calcium. lithium. sodium. potassium. magnesium has a slow reaction whilst calcium fizzes slowly and leaves an alkaline solution. they both fizz quickly with dilute acid. lithium floats and fizzes slowly becoming smaller, leaving an alkaline solution. sodium melts and moves around the surface fizzing rapidly, leaving an alkaline solution. This resource is a set of over 100 revision flash cards designed to help students revise gcse chemistry. each card has criteria on one side, and students need to use it to put together their own flash card on the reverse. the areas covered by these cards are: 1: atomic structure 2: bonding 3: chemical analysis 4: chemical changes 5: energy. The reaction between a metal and hydrogen is a redox reaction meaning oxidation (loss of electrons) and reduction (gain of electrons) occur at the same time. the reaction between zinc and hydrochloric acid produces zinc chloride and hydrogen. zn 2hcl zncl2 h2. the ionic equation is:. Gcse chemistry (single science) chemical changes learning resources for adults, children, parents and teachers.
