In experiment 11, at some point of the heating you will add 15-20 drops of water to the cooled contents. Why?Choose the best option: To cool the crucible faster To remove hydrogen gas from magnesium To remove oxygen gas from magnesium To incresase the mass of the crucible so that balance can weigh it precisely To prevent magnesium nitride formation by removing reacted nitrogen in the air from the crucible
