This blog will cover and explain the specification for Edexcel triple science course 2013 Chemistry. Hope it helps :)

Thanks Hanna You're a great help

Np, hope the exam went well :)

Really Nargis? ;);)

What about for molecules and formulae thanks

Formulae for example water. 1 mol of it would be , 1+1+16 = 18. 18g of water is 1 mol. Hydrogen is 1 but you times it by two, then add that to the 16 of oxygen which gives you 18.

The Chemistry Syllabus has changed…Here is a New blog for the 2017 Syllabus: https://igcse-chemistry-2017.blogspot.hk/
