When the Bunsen burners quit working at cooper JHS, students had to use candles to heat up their lab samples. At the beginning o
f class, the candle was 12 cm tall. By the end of class, the candles were 8 cm tall. Did a chemical reaction take place, yes or no? what evidence or lack of evidence do you have to support your answer?
Yes! A chemical reaction had took place as even if it seems like it is not a chemical reaction, it still had a reaction towards the wax on the candle that made it melt from heat.
