Does oxygen and hydrogen make water?
Does oxygen and hydrogen make water? H-2-Oh no! Just mixing hydrogen and oxygen together doesn’t make water – to join them together you need energy. The trouble with adding energy into the equation is that a large-scale chemical reaction of flammable hydrogen and oxygen (which is what keeps a fire burning) is likely to result […]
