Discussion
State whether the following is true or false.
Total mass is conserved in a reacting system even though moles are not.
Answer: B
Correct answer: True
Atoms are neither created nor destroyed, so total mass is conserved whatever reactions occur. Moles are not: \( \mathrm{N_2 + 3H_2 \rightarrow 2NH_3} \) turns four moles into two. That is why a mass balance can always be written as input equals output with no generation term, while a mole balance on a reacting species cannot.
