The Whole of AQA-THE RATE AND EXTENT OF CHEMICAL CHANGE. GCSE Chemistry Combined Science Revision C2

I want to help you achieve the grades you (and I) know you are capable of; these grades are the stepping stone to your future. Even if you don't want to study science or maths further, the grades you get now will open doors in the future.

The 'whole of the topic in … minutes' videos DO NOT comprehensively cover everything you need to know for your exams. It would be impossible to include 2 years of teaching in 1 hour. These should NOT be your only source of revision • Do the 'whole topic in... My exam predictions are just GUESSES!! I don't have any insider knowledge just years of looking at exam papers.

[@Sup7569]

Collision theory Collide, reaction High temp, high speed , high collection lots relation Higher temp, faster rate of reaction . Because particles have more energy so move around faster lead to more sucessful collations Powder more sucurface area Larger surface area , faster rate of reaction this is because more particles avaibke to react leading to more collisions Higher pressure/ cocnenatruon faster rate of reaction because more particles in a fixed volume so higher chance of collations Calayalis lower activision Reversible reaction Cool ->

Isn't endothermic reaction cooling it down because it is taking the energy from the surroundings

[@mariyaa9065]

yeah endothermic takes in energy from the surroundings making the outside cool down and exothermic does the opposite

[@jana-km1em]

@TheTrebleCleff no endothermic absorbs energy so it cools down exo releases energy increasing temperature

[@bri8167]

Which one is it omg

[@Yani_122]

@@bri8167 endothermic takes in heat and energy, cooling down the surroundings. Temperature decreases but internal energy store increases. Exothermic releases heat and energy, heating the surroundings. Temperature increases but internal energy store decreases.

[@user-gi3yr1gl7j]

Miss, why do we put a cotton bud as a barrier between the air and the content of the cronical flask?

[@nicoleamio]

in this type of reaction, the liquid "spits" which can escape from the flask if it were not for the cotton bud. thus it allows for the gases to escape, not the liquid.

[@LyraSilvertounge]

What did you add the marble chips into in the rate of reactions experiment with the inverted measuring cylinder? Was it hydrochloric acid or the sodium thiosulfate solution used before?

[@yoab_selemon]

it was hydrochloric acid

why do you have to draw a triangle for a tangent?

is this only for combined science not higher?

[@Primrose_Kitten]

Hi Jack David72, this covers both the content for combined science and separate science, If you're not sure which bit is which then I suggest you get my FREE revision guide from my website www.primrosekitten.com/collections which has everything clearly laid out for you

AQA do it

[@randomraul8539]

It’s never clear what’s foundation or higher. Only problem with these videos

if you have your specification you can make a list or check which you should or should not know :)
