Stoichiometric coefficients

Postby Dimitri Speron 1C » Wed Oct 03, 2018 4:55 pm

Is it acceptable to write the number 1 as a stoichiometric coefficient in a balanced chemical equation instead of just leaving the reactant/product with nothing in front of it? I ask only because I keep doing this out of habit and am not sure whether or not this is the proper notation.

Yeah I think it's fine. I personally don't do it because it's more confusing for me.

For doing stoichiometric calculations, typically reactants/products with a coefficient of one are not written with the number 1, as it is implied by convention there is one mole of that reactant/product. I personally have not seen the number 1 written down by any previous chemistry teacher.

It's not wrong. It's just unnecessary and unconventional. If you were going to publish a scholarly paper or something that contained chemical reactions, then you would obviously make sure not to include coefficients of 1 since it's against convention. But I can't imagine anyone taking points off for it on a test.
