    To what?

    Think about the polarity of the bonds..... also, what is more reactive, a double or a single bond? What about the relative steric effects of an OH group vs a H group? Or the dislocation of the electrons across the COOH group when in solution?

    Well i know that if a carboxylic acid is in solution it exists in the deprotonated form and forms a stable coo- ion, does that mean that propanoic acid is least reactive?

    Could u please clarify what u mean by steric effect? I dont think we have covered that at A2.

    hi all sorry to drop in on your page. i am also trying to find some help with chem. can any1 help me with this Q

    Calcium carbonate decomposes when heated:

    CaCO3 (s) > CaO (s) + CO2 (g)

    a) What mass of cacium oxide is produced from 150g of CaCO3
    b) What volume of carbon dioxide is produced from 150g of CaCO3

    IF I NOT WELCOME THANKS ANYWAY

    If a reactive part of a molecule has big bulky bits hanging off it, it makes it less able to react. Think of it like trying to get to the bar when there are a team of rugby players in the way.

    The carbanion is quite stable, so it means it is less reactive. Alcohol groups are also fairly stable.

    what is the Mr of:
    - CaCO3?
    - CaO?

    What volume does a mole of gas fill?

    If you can answer those questions, you can work through the rest.
