Ask a Teacher - Chemistry - Formulae and Equations - A Question from Eddie |
|
| Student Name |
Eddie |
| Question |
In a chemical
change the mass changes and a new product is made and it is not
reversible but how come in a chemical reaction the mass stays the
same and the total mass of reactants = the total mass of products?
|
| Answer |
In a chemical
reaction all of the reactant atoms become products so the mass that
was reactants is now products ie there are no reactant molecules
left so there is no reactant mass. The expression is just used to
remind you to make sure to check that you have got the formulae
and number of moles of products correct.
