Combustion Reactions Hydrogen Reactant True or False
All combustion reactions use hydrogen as the reactant. Is this true or false?
Combustion reactions, whether the reactant contains hydrogen or not, may be true or false. In fact, combustion reactions are violent oxidation reactions between combustibles and oxygen. All kinds of combustibles, such as carbon, carbon monoxide, methane, etc., can be burned in oxygen. When carbon is burned, the reaction formula is\ (C + O 2O\ stackrel {ignited }{=\!=\!=} CO 2O\), and there is no hydrogen involved; when carbon monoxide is burned, the reaction formula is\ (2CO + O 2O\ stackrel {ignited }{=\!=\!=} 2CO 2O\), and there is no hydrogen as the reactant. However, if hydrogen is burned, the reaction formula is\ (2H 2O + O 2O\ stackrel {ignited }{=\!=\!=} 2H 2O O\), and hydrogen is indeed used as the reactant.
Therefore, not all combustion reactions use hydrogen as the reactant, which is false.
