11:40 how does it mean endothermic when the temperature falls? isn’t it supposed to have higher temperature as it absorbed energy and the surrounding temperature must be lower?

[@DrMonaSeif]

Endothermic reaction absorb energy from the surroundings so the temperature of the surrounding falls (decreases)

[@fearnone0.o]

@@DrMonaSeif yes, so the temperature of the *surrounding* falls, not the mixture and that’s my point

For question 24 how do u find out the oxidaton states?

shouldnt Q10 be D? since if it is C then chloride should be formed at the anode not oxygen

[@ak27ara]

@@xx-zp4or It’s mentions “dilute”. If it’s a dilute aqueous solution, then the products will ALWAYS be hydrogen (at cathode) and oxygen (at anode), regardless of a halogen present, or a lower reactive metal than hydrogen.

[@DrMonaSeif]

The answer is C: Halogens only discharge if the solution is concentrated. In case of diluted solutions (OH)- ions are attracted to the anode and oxygen gas discharge instead . (D) is wrong because it's molten potassium oxide . Potassium will form at the cathode and oxygen at the anode. If a metal less reactive than hydrogen is present it will be discharged instead of hydrogen

[@ak27ara]

Yesss :)

Sorry, but could I get the ms for this pls? Thank you so much

Thx soo much!!

I can barely get higher than 30 on paper 2 any advice please?? :(( only 2-3 days left

[@DrMonaSeif]

Here are some advice that may help you: 1. Read the questions carefully and underline the keywords in each question. 2. Read all the choices provided (1 by 1) and omit the wrong ones; underlines what is wrong in each choice you omit helps a lot. (Using elimination) 3. Use a ruler/ ur hand to make sure you choose the correct question in the bubble sheets. 4. Do not spend more than a minute on any question, if you do not know the answer leave it for later. (Manage your time effectively) 5. Solve as many past papers as possible, paying attention to the questions you struggled with. 6. When you make a mistake make sure to know why is the answer incorrect and understand the correct concept, so you don't get it wrong again. Hope this helps and wish you the best of luck in your exams!

[@Saira-uu4xr]

@@DrMonaSeif Thank you so much! I'll keep these in mind and hope I can do better. The ruler tip is especially helpful and time saving. I'm so glad I asked
