Module 3 Question

Postby Rachel-Weisz3C » Sun Oct 07, 2018 4:06 pm

Can the mass of a product (or products) be greater than the total mass of reactant (or reactants)?
I would like to say that the mass of the reactants=mass of the product so no it isn't possible, but an option for an answer is: “under some conditions”… is it ever possible??

No. According to the law of conservation of mass, in a chemical reaction, the total mass of products must be the same as the total mass of the reactants.

No, because the law of conservation of mass. Additionally, that is why the percent yield will never be over 100%!

Lavelle said the only way this could happen was in a nuclear reaction, but that we didn't have to worry about this until later.

so it can only be the same as or less than.
