    It might be atoms and elements after that B1 6 marker
    Two years ago this question appeared:

    Complete the word equation for the oxidation of hydrogen.[1 mark]
    hydrogen + oxygen ---> ...................

    Some people put 'hydrogen oxide' or 'hydroxide'

    Were they accepted? You could also just put water I assume?

    Hydroxide was apparently wrong, only water in the mark scheme i think.

    Has Limestone ever been one the past papers as a 6 marker? I really hope it comes up tomorrow.

    They were looking for water. Extra information accepted hydrogen oxide. 'Hydroxide' was not accepted.

    I have never seen it appear as a six mark question.

    I'm good with balancing equations and have a fond memory of the periodic table. For the big 6 markers however (these are marked with a * in this post), I feel you need a good enough understanding of it that you could literally tell someone "on the spot" how it works. Memorizing all the chemical terms: ("Thermal decomposition*(For calcium carbonate), React, Reduction, Distillation*, Fractional Distillation*, Bonds, Molecules, Compounds,Soluble,Solvent,Soluti on, reactant, product, electron configuration...many more but I will leave you to revise those), and this is how I would imagine the 6 markers would work best, anyway. Keeping it succinct is always a good idea too.
