Ok, last question before i call it a day, for the question on why the student was unsure about the reactivity i practically wrote:
As you go down group 7 Reactivity decreases and Reactivity increases down group 2 therefore the student would be unsure over the most reactive compound.
I take it my answer would score no marks because i did not mention The compounds?
You may gain a mark, you have the general idea of what is happening and have shown that.
anyone got there paper back for the OCR jan 2012 chemistry (f321) paper back? and some one that could send me theres so i can compare answers! please! thank you!
