Eight resources on the thermal decomposition of the group 1 and 2 nitrates and carbonates. The first resource is a differentiated worksheet with the questions designed around the style of AQA, Edexcel and OCR exam papers and test students on every aspect of the topic including the reactions, observations, trends, theory of charge density/polarisation and finishes with a few questions on how we measure it experimentally. I looked at exam papers from all three exam boards when designing this resource so that it provides comprehensive coverage for my students. Answers are included. There is also a resource which goes through the qualitative observations associated with thermal decomposition of the carbonates and nitrates (what’s observed e.g limewater goes cloudy, brown gas of Nitrogen dioxide etc). I have also included a spider diagram of the reactions/observations and Power Points which explain the science behind it. There is then a hexagon activity and a challenge grid, both designed at stretching & challenging the students.
