sugar left. How many batches can I make before I run out of an ingredient? Which ingredient

runs out first?

Bell Ringer

N2 (g) + H2 (g) NH3 (g)

“You need 3 moles of H2 for every 2 moles of N2” is incorrect. Balance the equation and rewrite the statement so that it is true.

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 off and peed on the floor in secret. They didn’t

succeed in the market. Were scientists trying to fool children with an

exothermic or endothermic reactions?
