How do you add equations

  1. Sep 24, 2005 #1
    this crazy lab is askign me to add 2 equations (the same way you add math equations it says)


    H + OH ----> H20 + NA + CL ----> NACL = ??

    first time ive seen this :grumpy:

    Not sure about the "adding" part, but this makes sense:

    H+ + Cl- + Na+ + OH- --> H2O + NaCl

    You can't have plain Cl, must be Cl2.

    To add equations you add left sides and right sides separately.

    What are the equations you have to add?

    thanks borke, seems you nkow what your saying lol
    ill give you them, ca you add them so i seew hat you mean.

    reaction 1:
    NaOh ---> Na+ + OH- + 4.184 kJ


    reaction 2:
    NaOH + Hcl ---> H20 + NaCl + 5.25 kJ

    first reacions a decomposition one.

    anyways, id appreciate ifyou can do that then

    First reaction is dissociation, not decomposition.

    However, adding these two doesn't make sense, as these are apples and pears.

    What is exact wording of the question?
