    It said, "What property does V add to this compound?" I wrote high melting point there was no other metal in it. A metal in it would make the compound ionic, and hence, raise it's melting point.

    I wrote coloured compound first -_- Cut it later to write this.

    I wrote V makes the melting point of the compound high. Wrong? Also, I'm still curious about that tablet question. I seem to be the only one who used a different method.

    I think it said that the solution was acidified and NaOH was added and Ammonia was given off. Write down two ions present in the solution? How come H+ was present if the solution was acidified? If the question specified that only 2 ions were present, I think I'm wrong then.

    Need to know. Did it state that 'ONLY' two ions are present?

    Yes 500% bro. It was given at the very start of the question.

    The mass of the tablet was o.500 grams. It contained 0.312 grams of CaCO3, according to my calculations.

    Mr of Calcium Carbonate divided by Mr of Calcium Carbonate + Mr of Magnesium Hydroxide x Mass of tablet. ^ Given in our book. Used in past papers.

    I've ******* lost so many marks. What do you expect? FOR THE ONE LAST ******* TIME, TELL ME! Why can't we find the mass of CaCO3 by the Mr method?

    Liquid means it contains H+ and OH-. It does conduct, I know.

    It said HS in liquid form. Dumbass.

    HS conducts in liquid form.

    My simple question is, why can't it be solved by the Mr method? The question was, what is the mass of CaCO3 in the antacid tablet? I did it by the method Mr of CaCO3/Mr Of CaCO3+Mr of Mg(OH)2 X 0.500.
