    okay here goes, equations for contact process, all acid base equations, half equations for electrolysis, the combustion of an alcohol, zinc extraction equations, this isn't really equations but know how to derive a monomer from a polymer like propene from polypropene (might seem rediculously...

    To confuse you for the acid base question, they just replaced an ordinary acid with like hexanesulfphonic acid or something But by just applying the general equations for acid base reactions and pretending that the hexaneblahblah acid was sulphuric acid the whole way through i thought it was fine.

    Also there was ALOT of equation stating: "...mentioning eqations in your answer" "...state the equation for the reaction between..............."

    I mean it was mediumish, most of the paper were only 1 mark and 2 mark questions. I mean i worked quite fast fearing that i won't finish the paper, but i completed almost all of my answers and there was still 20 minutes left! so yathere was only one six mark question. Oh yeah, also there was a...

    HEhe, sure (i feel so rebel) well there was a couple. Overall the paper was on isotopes (like the first question) bonding, a little about zinc extraction (and the Electrolysis of zinc as well... but you do really need to study anything for that you just apply normal electrolysis stuff...) and...

    Important *caution*

    im not too surewhat to do but i would just mark on the center of mass (using the geographical centre), to find where to place it i think you would measure the diameter of the cylinder. Then place the cylinder on the ruler in a way that when reading the lower end and the upper end of the...

    you mean like this?

    Important *caution*

    Not too sure what you mean by the rule method but here: for triangle, do 3 prependicular bisectors that cut through the angles of the triangle. Where all three meet up is where the COM is. for a circle you have two choices, draw a square around the circle with the sides being TANGENTs to the...
