Question

Bob runs into science one day it is hot so he takes off his shoes and leaves his goodies the instructions say to pour 10ML of chemical A into a beaker and then add 5G of chemical b to it. Bob pours 10ML of chemical A into the beaker. He realizes that it smells funny, so he sticks his nose in the beaker and takes a deep whiff he then dumps some of chemical B into the container the beaker overflows the bell rings and bob leave the lab. What are 3 things that bob should have done differently?

Answer 1

Bob should not have stuck his nose on the beaker since he was generating CO₂ into the container. He should have also pour the chemical B immediately after the Chemical A to reduce exposure to other gases.
