    Anyone have all the physics past papers together?

    Ohh okay thanks. I downloaded them all. But now i have to open each file separately and click print. Can't i make them into one big pdf? or if anyone has one..

    Anyone have all the physics past papers together?

    Hey guys, So I'm just wondering if anyone has a pdf file or something with all the past papers since 2001 maybe? Preferably in order, i know i can get them on the website but I'm just wondering if there is a file ready for me to print! Thanks.

    That would have been PERFECT, if u didnt say aerobic .its anaerobic :D

    Why do you want to get C. Just get 40-50 and ull get an A ;) Or get 60-80 and get A*

    it doesnt need heat. I just double checked with my book. It specifically said IRON FROM THE BLAST FURNACE. and to stay molten, it just does as the reaction is exothermic. which provides the heat for it. So heat is needed, But you dont supply it. Answer is B

    EXOthermic means it gives out energy. If you give it energy then its ENDOthermic. Anyways goodluck in paper 3 tomorrow :D

    I do. But they want the final process when removing the carbon, Its an EXOTHERMIC reaction. so when adding heat, doesnt that make it endothermic. I need help in moles. Im stuck, and im really good in math :(

    I am 100% sure it is NO HEAT REQUIRED. As it specifically said From the iron in the blast furnace, which means it is MOLTEN. check ur book on that topic. heat isnt necessary. And its only nitrates. Its the ONLY thing that dissolves BOTH!

    Its Nitrates ONLY! And its CaO and O2. NOT HEAT. so A.

    Should be 32 in paper 1. And about 45 in paper 3 for an A.

    But in previous past papers i did. The same question came up and Yes, Not all metals react with acids. For instance, Try mixing gold with HCL. what will happen? Nothing.

    Heat isnt required. Google it. They said IRON FROM A BLAST FURNACE. i checked in my book. it says only CaO and O2 are needed. In an oxygen chamber, its already hot, and its an exothermic reaction, giving it heat would mean its endothermic wouldnt it, Wait the exam is over. Lets focus on paper 3...

    Its not analysis bro. You need the solubility table. And yes Barium PRODUCES a precipitate in sulfate. And silver + chloride produce. Its to do with solubility

    Nitrate OFCOURSE. Only nitrate dissolves all of the,

    The overhead cable IS aluminium. But i wrote copper as the Elesctrode. I think its wrong but as it SADI SCHOOL it cant be platinum. They wont be able to use it. And copper doesnt reach with HCL. HEAT ISNT NEEDED FOR STEAL. They said IRON from BLAST furnace which is already hot so no heat. I...

    Chemistry Paper 6 question bothering me

    remember that last question about "which fuel is more exothermic" Everyone said heat till 30 or something then see mass difference. I did it another way and just want some clarification if its write. in summary i said "Clamp and take mass of fuel... then heat until the mass decrease By 5g or...
