method 1

Postby alanaarchbold » Sat Jan 26, 2019 4:52 pm

In method 1, when adding the two equations do you cancel out molecules if there's one on the reactant side and one on the product side?

Yes, if there is the same chemical on both the reactant side and product side, then it cancels out when you add the equations.

Also, remember that they have to be the same state.

Yes, one of the points of adding the equations together is to cancel out compounds that are not needed.

if they are not in the same state does the molecule just get brought down into the final equation?
