who's good at chemistry?

http://www.ocr.org.uk/Images/131286-question-paper-unit-f321-atoms-bonds-and-groups.pdf 4Cii) help pls. for some reason for the answer the moles of ii) is half of the moles of i) but I don't see a 2:1 molar ratio in the balanced equation, what is going on. thanks.
Sorry you've not had any responses about this. :frown: Are you sure you've posted in the right place? :smile: Here's a link to our subject forum which should help get you more responses if you post there. :redface:

You can also find the Exam Thread list for A-levels here and GCSE here. :dumbells:


Just quoting in Puddles the Monkey so she can move the thread if needed :h:

Group 2 metal, hence the equation is of the chloride is XCl2, and therefore for each mole of that you must have 2 of AgCl to balance chlorines
I got the answer as Magnesium.
You work it from backwards. Ill post the pictures of my working tommorow? Im really sleepy and my phone needs to charge
