A homologous series is a group of organic compounds with similar chemical properties and structural formula and a gradual change in physical properties e.g. melting point and boiling point. Below is a graph of boiling point against number of carbon atoms for the various homologous series covered in GCSE/O level Organic Chemistry:

Thus, formula is H 2 O. The formula of a compound can be calculated if the number of moles of the combining elements is known. Empirical formulae show the simplest ratio of atoms present. Molecular formulae show the actual number of atoms of each element in one molecule. Percentage yield = actual yield/predicted yield x 100 International GCSE Plus. Oxford AQA International GCSE Chemistry is available with International GCSE Plus. This is an optional endorsed component in which students can explore any aspect of Chemistry through a research-based piece of analytic work.

PETITION OxNotes › GCSE/IGCSE Notes › IGCSE Chemistry › Electrolysis Simple explanation of Electrolysis Electrolysis is the process of decomposing (breaking down) an ionic substance, called an electrolyte , into simpler substances using electricity. NOTE: You can only use big numbers to balance equations, not the small numbers you use when you’re working out the chemical formula for the compound. For more discussion on balanced equations, have a look at our videos on this topic: AQA , Edexcel and OCR. Each video takes you through detailed worked examples.
