This week, in two separate glass Erlenmeyer flasks, you will be generating hydrogen gas, which is a combustible gas (meaning that it burns easily) oxygen gas, which supports combustion (more specifically, this means oxygen must be present for combustible materials to burn). What are the two major safety risks this week? Select both!
a) Nothing really. Hydrogen and oxygen are benign gases that already exist in the air we breath.
b) If hydrogen and oxygen wastes are mixed, the waste container will now have both a super combustible gas and a gas that readily supports combustion (e. g. the waste container could create a pressurized explosive fire).
c) Obviously Dr. Greenhalgh wandering around the labs, fawning over your pipette bulb rockets.
d) If a gas generating reaction is not allowed to vent through the tubing and the pressure exceeds atmospheric pressure, it could cause the glass to shatter.
