The magnesium metal also reacted with the oxygen in order to produce the white ashes. You are HOT!- 1. As a chemist, I could determine the identity of the gas because the mixture of substances was boiling or bubbling and a slight steam was rising from the substances therefore making it a gas. 2. It was an exothermic reaction because energy was being released and the bottom of the test tube was really hot.
