Simple mixing of both hydrogen and oxygen molecules won't yield water. It requires a huge input of energy to activate the reaction. This energy should be in the form of heat.Hydrogen is a flammable gas, and oxygen is a supporter of combustion (supports burning). Hence, bringing both of them together ... Read More
