    Pandas are universally loved. Pandas are adorable. Any of these two (there can be more).

    Yeah, I know, but different students attempt the papers, you never know what to expect.

    No a layer of zinc coating is applied.

    No it is specifically by Zinc. It is a coating of one or more layers of zinc. Only using Zinc, and it is coated or applied to the body whereas in Sacrificial Protection you just attach the piece of reactive metal so that oxygen reacts with it instead.

    Well yes, so if 5 moles of water are present and only 2 moles are reacting (calculated from mass) so it is in excess.

    Well, its easy to figure that out by taking in account the moles and the masses/volume.

    The substance that has less MASS becomes limiting agent.

    Yup. :D

    Galvanizing is applying a coat of ZINC to protect iron/steel from rusting. It can be done using electrolysis. In sacrificial protection, any metal more reactive than iron are used, we attach pieces of the more reactive blocks near (or on) the iron body/pipe and the oxygen reacts with the more...

    It's the reactant that completely reacts (or it's the reactant that is NOT in excess).

    I don't know why use guys use 'limiting agent', it feels so odd (I know it's correct) since I've read 'in excess' from the beginning. :LOL:

    True, False, Cannot Tell. For the last one, I even did some research, the SECOND panda in America was lent by China. The first was there in the 1930's.

    On one side, I hear people saying that IGCSE's are much easier in terms of paper patterns and procedures. On the other side, they have such low thresholds. I'm confused. :confused:

    Displayed formulas are a type of structural formula. So are condensed formulas.

    Well, they said a SINGLE word that suggests that 'VERY OFTEN other people got stuck'. The key words were very often not stuck.

    If you consider IGCSE English. The thresholds are as low as 70 for A*'s sometimes. But honestly, it is almost completely different from our paper.

    Well, I still believe CIE is mad. In their OWN questions they show structural formulas having OH not O-H and its in their books as well. Now, they expect students, in all that tension, to figure out these small details, I hate them! :mad:

    Structural Formula is the one shown, it is written in my book as well that structural formula can be displayed by both drawing and writing, but the latter is not common now, it was used in the old days. It is the condensed formula. Now, we use diagram representations of these. You can check from...
