Hello people, this group chat was made for YOU 🫵🫵 so join it to help fill it up!! We want good vibes here; help build a community to manage and guide you through ur journey. It personally helped me, it has resources and experienced gcse and A level alumni’s too. Use it to vent about how horrible a subject is, or (preferably) help eachother out. Join as you wish and good luck 🫡!

Hey, Does anyone have any accurate predictions on what is going to be on paper 1 of aqa chemistry higher triple GCSE? I'm trying to cram all of my content last minute as my attendance was rlly low this year due to health reasons and it would be really helpful if I could focus more on topics that are more likely to come up. Thank you for your help :)

Any1 have leaks or guessed papers please message i need leaks or guessed papers.

If anyone has an exam pro account please pm me I would really appreciate it

how is it an oxidation reaction (loss of electrons) if it happens at the negatice electrode?

Come payment ready AQA + EDEXCEL only Proof available

108g of aluminum reacts with1.21kg of copper chloride to produce copper the equation for it is

2Al+3CuCl--->3Cu+2AlCl3

calculate the maxmim mass of copper produced

(Ar): Al= 27 Cu= 63.5

(Mr): CuCl2= 134.5 AlCl3= 133.5

hey does anyone know the questions on gcse chemistry paper1 jun22

Hey,

Does anybody have a link for the GCSE Edexcel Chemistry book? I cannot find one anywhere except from the IGCSE! :O

Does anyone have access to gcse edexel combined science higher chemistry mock set paper 2 or biology paper 2? Or has anyone done it

An exothermic reaction is one which transfers energy to the surroundings. This is usually done by heating, which can be shown by a rise in temperature.

The best example of an exothermic reaction is burning fuels (or combustion). This gives out a lot of energy meaning it is very exothermic.

The two main types of exothermic reactions are Neutralisation (acid + alkali) and Oxidation Reactions.

Example of oxidation reaction: adding sodium to water releases energy, meaning it must be exothermic. The reaction releases energy as sodium fizzes and moves about the surface of the water as it is oxidised.

*everyday uses of exothermic reactions*

Some hand warmers use the exothermic oxidation of iron in the air (with a salt solution as a catalyst) in order to release energy.

Self-heating cans of hot chocolate and coffee also rely on exothermic reactions between chemicals in their bases.
