Which chemical reactions are not possible according to dalton's atomic theory?

Accepted Answer

Hey everyone. So this question wants us to determine which reaction or reactions are impossible based on Dalton's atomic theory. So here we're talking about our conservation of matter, which is essentially telling us that matter can neither be created nor destroyed. So the amount of moles that we have in our react inside for one element should come up to be the same amount of moles for that exact element in our product side. So let's go ahead and look at reaction A. So for reaction A we have one mole of carbon and we have formals of roaming in our react inside. And in our product side we ended up with one mole of carbon and four moles of hydrogen. So as we can see right here, this would be impossible because we started off with carbon tetra bromide and we ended up with methane. So this would be one of our answers. Looking at reaction B we have hydrogen plus oxygen and we end up with water. So we have formals of hydrogen and two moles of oxygen in our react inside In our product side, we have four moles of hydrogen and two moles of oxygen. So this equation is completely balanced and this is completely possible. Now let's go ahead and look at reaction. See now for reaction, see we have two moles of nitrogen and we react this with six moles of hydrogen and in our product side we end up with two moles of nitrogen, six moles of hydrogen and we also added on some copper. So as we can see right here, this reaction is impossible because we ended up with copper, but we didn't have any copper to begin with, so that would not occur. So these are going to be our answers for this question. So I hope that made sense and let us know if you have any questions.
