    chemical equations
    I have a test on chemical equations and I'm not very good at learning it in class,
    I just need the most simple useful information any of you know about chemical equations to get me started

    Thank you :)

    What are you exactly not good at? Balancing the equations? Making the products? Giving the formulae of the chemicals?

    You just got to remember that whatever the number of base elements is on the left before they react, has to be the same as what's on the right at the end... for example

    2H20 > 2H + O2
    2 hydrogens and 2 oxygens on both sides.

    Two water molecules go to 2 hydrogen and one oxide on the other... I think its oxide...
    Man am I channeling yr 12 chemistry haha that was so long ago... and besides I didn't really pay attention to the teacher much... I was more interested in flirting back then hahahaha

    Its just sort of grasping the concept that it has to balance..
    Anyway hope this helped

    The equation is:

    2H2O -> 2H2 + O2

    2H2O : 4H and 2O
    4H become 2 hydrogen molecules, i.e. 2H2
    2O become 1 oxygen molecule, i.e. O2

    Oh that make you feel good did it?
    My example was wrong, so sue me.
    At least I had an input and wasn't just proving someone wrong.

    The corrected equation can be a good info to 'tiarbanana', to avoid such mistakes dealing with, here, balancing equations. I wasn't really 'proving someone wrong'. People learn from errors, you certainly know. Anyway tiarbanana can ask questions (better if the question is clearer) anytime and we are here to help.
