Customer Question

when u write the balanced equation in chemical reactions, if its not react, the equation is going to be the same before the reaction?

Expert:  Dr WLS replied 11 years ago.
The balanced equation of a reaction describes what reactants can be converted into what products, whether or not the reaction goes to completion. Most reactions go in both directions, and never go completely one way or the other.

It is not customary to write a reaction equation with the same reactants (on the left) as products (on the right), even if the reaction does not proceed to a significant extent.

Reply to William Shackleford's Post: ok. so for example, HCI does not react with Cu
so when i write the balanced equation, it will be HCI+Cu--------> HCI+Cu?
is this corect equation?
Customer: replied 11 years ago.
Reply to William Shackleford's Post: i need to do the balancing equation with chemical reacions.

1. FeCl3 with Mg, Zn
Expert:  Dr WLS replied 11 years ago.
I have answered your original question and first followup about the (balanced) reaction
2 HCl + Cu -> CuCl2 + H2

I have already done the balancing of FeCl3 with Mg and Zn as part of another post thread, which you may have written separately. As far as I am concerned, this question is closed.
Expert:  xarqi replied 11 years ago.
With the greatest respect to all involved, there is no reaction
between copper and hydrochloric acid.
Expert:  Dr WLS replied 11 years ago.
Xarqi is correct about Cu not reacting with Cu. I appreciate his comment, which has helped me relearn some chemistry that I should not have forgotten.

The balanced reaction that I wrote for Cu + HCl does not take place.

Please accept my apology for the error.
