year 11 past papers based on modules (1 Viewer)

[jane1820]

does anyone have any past papers/questions based on modules instead of a full paper with all modules?

its so time consuming and annoying that i need to go through all available papers on thsc one by one and find the questions

in case anyone has any, i need all past papers/questions u have regarding module 1 chem plz

Not a very long one, but unfortunately this is the only one for mod 1 I have

Nah but I have my original paper so based off that here are the answers (also time limit was 40min):

Spoiler: Answers

1. B
2. B
3. C
4. C
5. C
6. A
7. D
8. D
9. D
10. B
11 a) eg. graphite, fullerine, diamond
b) 1 mark each: similarities, differences, example comparison using the examples in a).
12 a & b) 1 mark: identify intermolecular and intramolecular forces, 2 marks: explain effect of one of these forces on physical properties with relation to substance
13) 1 mark each: define electronegativity, explain how it relates to each of the 3 substances and determines bond type
14) 1 mark for each correct diagram, search on google for correct structure
15) a) 1 mark phosphorous:
1 mark potassium:
b) self graded, could include: comparative language, brief description of both models, particle vs wave, fixed orbital vs probability system, 2d vs 3d, suborbitals. 2-3 sentences is enough

YO bro how do i do this

Amplitude = height of the wave = loudness (higher is louder)
Wavelength can get you frequency. Because all sound waves move the same speed given they are moving through the same material, the closer the waves are together (shorter wavelength), the higher the frequency (number of oscillations passing through a point per second). A higher frequency just means a high pitched sound, and a low frequency is a low pitched sound.
Hopefully you can figure out the answer from that, but if you REALLY need the answer:
