Lila is using a Bunsen burner. She has all of her chemicals on her workstation. Which would be the best lab practice?

Answer
A
putting the burner on a stand to keep it away from chemicals
B
keeping the chemicals close to the burner for easy access
C
leaving the burner on across the room and moving back and forth
D
finding a new lab that does not use a burner

A burner is an open flame, so chemicals should be kept away from it to reduce the risk of fire. Putting the burner on a stand away from the chemicals is the safest choice. Keeping chemicals close to the flame, as in choice B, increases the danger.
