Question

A student observes the model and claims that the total mass of the reaction is conserved. Is the student's claim correct? Why or why not?
A.
Yes, because the reactants and products are made of atoms of the same elements.
B.
Yes, because the number of atoms of each element is the same on both sides of the equation.
C.
No, because the arrangement of atoms is different in the reactants and products.
D.
No, because the total number of atoms in products is greater than the total number of atoms in reactants.
