Every deck we have for Energy Changes, part of AQA GCSE Chemistry. 94 questions written against the published specification, free to study with no account. Each deck schedules its own reviews, so cards you find hard come back sooner than ones you have already got right.
Which way energy is transferred in each type of reaction, everyday examples and uses, and the required practical measuring temperature change.
Drawing and reading reaction profiles for both types of reaction, what activation energy means, and how a catalyst changes the picture.
Why breaking bonds takes energy and making bonds releases it, and calculating the overall energy change of a reaction. Higher tier content.
How chemical cells produce a voltage, the difference between rechargeable and non-rechargeable, and how a hydrogen fuel cell compares with a rechargeable battery. Chemistry only content.
Energy Changes is one topic of AQA GCSE Chemistry. The other topics are all covered too, in the same format.
