    Chemistry Paper 4 (ATP) Discussion

    By increasing current i think u would only increase the rate at which silver is deposited, not the amount

    Chemistry Paper 2 discussion =)

    Hey rose , The answer cannot be ethane as ethane is an alkane and doesn't react with steam. The answer can neither be ethene as the addition of ethene to steam is known as a hydration reaction Fermentation is when a mixture of glucose and yeast is left to stand in anaerobic conditions at...

    Chemistry Paper 2 discussion =)

    The question, I think, was "What is the effect on the equilibrium when temperature is increased?" According to Le Chatelier's Principle, dynamic equilibrium shifts backwards to decrease the temperature as the backward reaction is endothermic. Thus, the yield of SO3 decreases and that of O2 and...

    The temperature is correct. Am not too sure for the concentration. That would increase the rate.

    Chemistry Paper 2 discussion =)

    Take a breather member... Chillax. :D I dont think u will lose marks. Because in part (a) u already stated that there is a layered arrangement in graphite and not diamond. So when u answered in part (b) why graphite is soft u talked about the layers. So it more or less implies that this doesnt...

    Hey member, Your answer sounds good. I wrote approx. the same thing. :D For the first part, 1) In graphite, the carbon atoms are arranged in layers and in hexagonals while in diamond, the arrangement of carbon atoms form a tetrahedral structure. 2) In diamond, one carbon atom is covalently...

    Yes Chief!!! :D (a) Glucose (b) Mixture of glucose and yeast kept in air-tight container/ anaerobic condition/ absence of oxygen and a temperature around 37 degrees celcius. (c) C2H4 + H2O ----> C2H5OH (sorry cant write it properly) reactions conditions: 350 degrees celcius, 65 atm and...

    As far as i remember... Name the organic compound needed for fermentation State the conditions for which fermentation would take place more rapidly Write the equation for the reaction between ethene and steam Then there is the reaction between ethanol and ethanoic acid. Name this type of...

    Chemistry Paper 2 discussion =)

    It was very easy compared to that i had been prepared for... Thats awesome.. :D On the other hand that means that there will more severe correction for this paper by Cambridge or maybe the paper 4 will be tougher... :P :cry:
