    Also whats the actual definition of rate of reaction??

    Errors (i always get confused- failed phy cause of it)
    how do you work out Max % error? (i don't understand what the max part means)
    why is the problem of sulfur dioxide being produced negligible?? (i think it something to do with the state its in)

    Why is it necessary to clean the ribbons of mg or iron before and experiment???
    Also what is the result of reacting mg with cold, hot or steam (water)???
