# How do you add equations

## Main Question or Discussion Point

this crazy lab is askign me to add 2 equations (the same way you add math equations it says)

so

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

first time ive seen this :grumpy:

## Answers and Replies

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.
thanks

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
thx

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?
