OCR GCSE Chemistry A- C7 + Ideas In Context, May 24th 2012. OFFICIAL THREAD

Is this the fermentation one? If it is the reason is because you're assuming all of the glucose will be used up. Some reactants aren't used to their full potential in terms of the amount of product that can be formed.

It was 0.495g I wrote 0.5g as well just in case

Correct. Definatley not a trick question.

SHUSH GUYS!

BY TALKING, STUDENTS DOING iGCSE CAN CHEAT AND RAISE GRADE BOUNDARIES. PLEASE DO NTO WASTE YOUR EFFORT ON DOING THE EXAM JUST SO SOME PEOPLE IN KUWAIT/INDIA CAN ACKNOWLEDGE THE ANS/QUESTIONS!

Please wait until AFTER MIDNIGHT!

Excuse me? That only applies to Edexcel.

Please get your facts right before making statements like that.

I thought it was a pretty average paper? I found the question with the aspirin impossible.. I just shoved a load of numbers down >.<

But other than that question, it wasn't too bad- I didn't majorly stress over any of the other questions, from memory, I managed to answer them all I least, but then I know that there'll be loads where I phrased it wrong, or missed out details, and dropped marks that way!

I was worried that I'd lost way too many marks, but I'm really reassured to hear the grade boundaries are so low- we'd not looked before, and we were all expecting it to be 49 for an A*

I have 49 for units 1-3, 44 for units 4-6 and a mid A* on my coursework, so I'm hoping I managed to scrape an A* overall!

Just wandering, if I got 40/40 in coursework, 50/50 in one exam and 49/50 in another, what amount of marks would I have to get in this exam to get A*. Freaking out that I didn't get enough :'(

What does an exothermic reaction look like?

I put a horizontal line through the middle am I right?

ah crap, have a horrible feeling I did really bad in this paper. For aspirin question, I got 0.49something something something. I've never liked titration questions.

I was surprised that nothing about alkanes and sustainability came up, also surprised about the fact that there was 2 questions about making ethanol, as it normally doesn't come up and when it does its only one Question.

Overall i think it was a fair test.

first instincts are the best

What did you guys put for the last question? Explain why its made under 37.9g?
