Why is Hydrgen dangerous?
It burns very easily in air. With the right ratio of air-to-hydrogen, it is explosive.
What is the reaction taking place as the hydrogen burns?
Water is formed when hydrogen gas burns (reacts) with oxygen (from air) 2 H2(g) + O2(g) --> 2H2O(l)
What is the colour of the flame when sulphur burns in air?
