unit 5 chemistry (btec applied science)

has anyone found a good way to revise chemistry especially all the extraction topics? do i just use the revision guide or the big text book too- has anyone found any good youtube videos summarising the extraction methods too?

How was itttt

what did you get for hess law?

what did you get for hess law?

Who else got 9000 and smthn for the shc

Meee

im sitting my exam this summer,what topics came up for chemistry if you guys do not mind telling me

Mostly electrolysis and chemical formulas and a little bit of enthalpy.

sorry to bother you again, but i wanted to ask what came up in bio.I have done alot of revision on physics and chemistry and got distinctions on the mocks for em, but bio is letting me down

No worries bro, If I can remember correctly it was:
. Cell surface membrane
•Kidney structure
•Cardiovascular disease (maybe one question)
.lungs
.the heart(focus on this)
•passive and active transport
• Osmoregulation
My advice: focus on kidneys, heart passive/active transport and on osmoregulation as these are the most common and cost the most marks

your a life saver thanks so much bro

Anytime mate, feel free to ask any questions.

Do you know if these are similar questions that will come up in summer ?
If possible do you remember what topics came up on chem and physics it would be great if you could just give me an overview xx

I can't really say for sure if they will come up in summer but it's better to be safe than sorry and unit 5 seems to have a trend when it comes to the topics, with that being said:
For chemistry:
.enthalpy came up (Hess law 5marks i think)+ profile diagrams
. Electrolysis
. Reversible reactions &chemical catalytists (e.g vanadium oxide)
.aluminium
.reducing agents
.Electrolysis of brine e.g membrane/diaghram cells( this was a big one)
.Alkanes and alkenes(structural formula) in general
Physics:
.Fluid viscosity
.Thermal energy( i specifically remember a question of heat pump in a house; so definitely revise that)
.energy conservation ( mostly tickbox)
. Refrigerators
. Shape change (elasticity)
Advice: for chemistry focus on enthalpy( especially calculations for Hess law) as a whole( this will get you the most marks), electrolysis, fully understand how the cell diagrams work (e.g products and what chemicals are lost during the process) and deeply revise alkane and alkene structures (e.g skeletal,displayed, isomerism, haloalkanes and alcohols).
Whereas for physics focus on fluids, Bernoulli’s principle,thermal energy( how heat pumps and refrigerators work as it is quite confusing), shape changes (e.g plastic deformation)+ cycles (e.g Carnot)
Side note: I might have forgotten 1 or 2 topics that came up across the exam but here’s what I remember
