Before you leave today, write one question you
could ask about the content we studied today.
The question should be either short answer and
can begin with words like explain, predict,
evaluate, or compare. Avoid questions that
simply ask for a list.
Write them on a sheet of paper to be handed in

N2 (g) + H2 (g)  NH3 (g)
“You need 3 moles of H2 for every 2 moles of N2”

Pull ups diapers marketed a diaper that became
cold when the urine reacted with a chemical in
the lining. The idea was that little kids would
start using the toilet because they didn’t like
their privates cold. Instead, kids took the diapers
