Q4. C Motion of gases is random regardless of mass and they take up whatever space is available Q15.D (You skipped somehow) C2H5 : CO2 = 1:5 So moles of CO2 = 5*0.1 = 0.5 mol Volume of CO2 = 0.5*24(Molar gas volume) =12 Q31. B Question asks for Lowest percentage not highest
Hey! So basically according to the kinetic particle theory all gas molecules have a random constant motion. Thus, they are spread out randomly in a given space regardless of their densities.... The density will only affect the rate of diffusion... Hopefully, that makes it clear.
Q4. C
Motion of gases is random regardless of mass and they take up whatever space is available
Q15.D
(You skipped somehow)
C2H5 : CO2 = 1:5
So moles of CO2
= 5*0.1
= 0.5 mol
Volume of CO2
= 0.5*24(Molar gas volume)
=12
Q31. B
Question asks for Lowest percentage not highest
31. Answer is B. Question asks for LEAST percentage by mass
According to the mark scheme, the answer to Q4 is actually C.
I had the same thought process you did, so could you please correct why B is wrong?

omg so nicely explained. tysm !
In question 11, if we put 5 at O2, 5×2 is going to become 10 moles of Oxygen then
Y will be 4 and Z will b 2 so it will be balanced
but can you please solve other specimen papers too of 2023
Which class is the paper of??
O levels
👍🏻👍🏻
I want theory paper answers for this specimen paper 2023
Lol.. you never did q15 😁
its easy anyways
paper is in 3 hours lmfao
xd
😂
I guessed like 20 Mcqs 💀
