    How does a catalytic converter work? (4)
    - adsorption of reactants
    - bonds weaken
    -desorption of products
    the formula
    NO+CO GIVE 1/2N2+CO2

    whats everything you know about polymers?
    polymers are made up of monomers which is an alkene
    polymer waste is a problem lack of space in land fills etc
    we can recycle them which involves sorting and reclamation
    scientists are begining to develop biodegradeable plastics
    we should recycle polymenrs
    burning old polymers can also be a good fuel cource but this produce co2
    polmer waster can also be used in feedstock recycling

    Oh and answer mine while you're at it
    Biofuels are fuels such as ethanol, methanol? which i think burn more cleanly so have environmental benefits and are also are looking to replace the finite sources we have now

    adv of fermentation; low temperatures and pressures used so less energy,

    disad of fermenation; not 100% atom economy, only 14% conversion

    adv of hydration of ethene; 100% atom eeconommy achieved

    disadv of hydration of ethene; high temperatures and pressure used, which could be a health risk for workes

    anything ive missed out??

    the amount of radiation it can absord i think its infared radiation? correct me if am wrong

    and its relative concentration in the atmosphere

    the amount a gas has and effect is measured by its GWP global warming potential score
