AQA GCSE Chemistry Paper 1 Higher Tier Triple (8462 1H) - 17th May 2024 [Exam Chat]

I do edexcel maths and they actually told you it was positive, in this case they were vague about it like a cat meeting its new born mother

Let’s see what aqa says, if your right I will get you a trip to Hawaii but if I am right you have to get me a trip to Hawaii. Deal?

Lsdto

nah i don't like the US (also what does lsdto mean)

It doesn’t make a difference if you get 947 as they weren’t being specific, idk why you say they have done this before, bring me proof they have and I will believe you…

I understand where all the confusion is now. Some people think that overall energy change being positive means that you have to flip the symbol into a negative so that it fits an exothermic reaction. But others and I used the idea that reactants - products = 2219, so rearranged it to find the reactants. It seems strange to change the question where it says the overall energy change is 2219 to -2219 to fit the question.

the q never said the overall energy change was positive ****** otherwise they woulda put a plus sign. the whole purpose of the q saying it was exothermic is to make you figure out if the o.e.c was positive or negative. the word change can mean either increase or decrease. use your comprehension skills mate

you can’t change the maths last question and say k is negative when it clearly said it was positive, same for this question, they said 2219 was positive (ik exoteric reactions are negative) but believe me, aqa must have made a mistake, they don’t usually do this!

it never saif it was positive. Where is the "+" sign huh where is it??

Dude you you’re out of your mind! You never put a plus sign in front off a number, you would never say +1+ 2 when counting so don’t expect it here!

it never saif it was positive. Where is the "+" sign huh where is it??

Why are we still debating over this? Personally I got 947 and it most likely could be wrong. But you still get method marks regardless if its right or wrong.

seems like you have never done an aqa chemistry past paper before. they usually put a plus or minus sign before the oec when they want to you calculate bond energy in a typical 4 marker. the extra one mark comes from figuring out if it was positive or negative.

Ikrrr. Can people please move their focus to the physics chatroom now😭. Its so empty

Dude I have done all past papers for sciences

So in the future when you get a value, say 300, it doesn’t say positive so you assume it’s negative, that is crazy to me. 2+2 is -4 now. Nice one bois…. Because there is no positive number in front of 2….
