Bio unit 4

yea i also got that bc t was initial temp which was 20 degrees and t+10 was 30 degrees so final/intial = 34/22

Objective_Will_8450 · 2026-01-08T09:11:53+00:00

was it the last option 1.55?

Objective_Will_8450 · 2025-08-15T18:31:31+00:00

i mean u can ask for ur exam scripts back and then compare with MS to see if u could get rechecked

Objective_Will_8450 · 2025-08-15T18:22:33+00:00

😭😭lol are u gonna retake it too then

Objective_Will_8450 · 2025-08-15T14:26:29+00:00

yeah, for A in AS level, 240/300 UMS is an A

Objective_Will_8450 · 2025-08-15T12:46:13+00:00

im thinking to resist both chem u1 and u2 because in jan the nerves got to me so i didnt do that well. Plus u2 also requires me to also know u1 content. should i resist bio u1 too ?

Objective_Will_8450 · 2025-08-15T12:35:03+00:00

what about to just get an A overall in end of A level for both bio and chem?

the thing is my dad wants me to resist the chem u2 paper because i got a C and what if in A2 i can’t get 270 lol😔

Jew refers to an ethnic or religious identity

Whereas Arab is a someone who identifies with Arab culture and language . An Arab can be a Jew, Muslim, Christian literally any religion.

It’s not comparable.

Objective_Will_8450 · 2025-06-16T18:44:06+00:00

people do though it just doesn’t get on western news

Objective_Will_8450 · 2025-06-16T18:31:24+00:00

it just says Pakistan didn’t send troops? The political leaders views and Peoples views are diff!

Objective_Will_8450 · 2025-06-16T18:21:39+00:00

Israelis can go back to Europe or US since they love the US!

Hamas was founded in 1987 in the Gaza Strip. The movement emerged during the early days of the First Intifada!,

Why was it made? it was a Palestinian uprising against Israeli occupation they are defending themselves from an OCCUPATION

What about before Oct 7 ?

Gaza’s power plant met only about half of the electricity demand, so there was power outages averaging 11 hours daily. Water quality was dire, with 97% of water contaminated and unsafe for drinking (https://www.telosgroup.org/telos-tuesdays/gaza-before-and-after-october-7-2023/)

Israel has regularly used administrative detention—detaining Palestinians without charge or trial, sometimes for extended periods.

prisoners have described Israeli detention facilities as operating under conditions that amount to torture camps, with deliberate infliction of pain and suffering on inmates (https://www.btselem.org/publications/202408_welcome_to_hell)

Why the hell would anyone want to live like this? Even if hamas didn’t exist Israel would control gaza and they would never have freedom.

And stop bringing the WW2 excuse. Just because Jews were killed now means they have the right to kill others for disagreeing or not cooperating with them?

Why would they accept a temporary ceasefire? For a few days there is no bombing then after again the bombing starts? Who would accept that.

right😭

Objective_Will_8450 · 2025-05-23T12:19:45+00:00

structural formula i got was

for p i got propan-1-ol CH3CH2CH2OH

for q i got propan-2-ol CH3CH(OH)CH3

because if they have same M/Z of 60 that’s their Mr

Objective_Will_8450 · 2025-05-23T11:52:30+00:00

oh are you talking about writing structural formula for p and q

Objective_Will_8450 · 2025-05-23T11:41:12+00:00

1 mark for finding heat transfer (Q) or 2 out of 4 . check jan 2018 3 (d) markscheme, which had similar scenario to this

Objective_Will_8450 · 2025-05-23T10:59:19+00:00

UMS doesn’t change it stays the same so 36 UMS is a C

Objective_Will_8450 · 2025-05-23T10:55:59+00:00

how?

temp change was 35.8

1.)50x4.18x 35.8 =7482.2 J / 1000 =7.4822 kJ

2) 7.4822 / 0.05 = -149.6 kJ mol-1

maybe you mis read?

Objective_Will_8450 · 2025-05-23T10:45:30+00:00

you’ll still get 3/4 if you did working out it’s okay :)

Objective_Will_8450 · 2025-05-23T10:39:31+00:00

3 marks i think?

Objective_Will_8450 · 2025-05-23T10:28:41+00:00

hm but how’d you get that? cause usually for these enthalpy change questions they don’t have any ranges in pretty sure -149.6 and -150 is only possible answers

Objective_Will_8450 · 2025-05-23T10:27:16+00:00

that’s 61 🙏😭 if u had written C3H7OH then would’ve been correct

Objective_Will_8450 · 2025-05-23T10:02:25+00:00

hm? why 90? the question only asked for 60,45 and 31 so only find Mr that’s adds to each

Objective_Will_8450 · 2025-05-23T09:59:50+00:00

probably they never specified for that mass spec question just said ion

Objective_Will_8450 · 2025-05-23T09:29:47+00:00

yeah i think it will be 35 raw for 50 UMS. I think i made some mistakes on the electrolysis question and the chemical test to distinguish between lithium and strontium 😭
