The bicarbonate ion (hydrogencarbonate ion) is an anion with the empirical formula H C O 3 â and a molecular mass of 61.01 daltons; it consists of one central carbon atom surrounded by three oxygen atoms in a trigonal planar arrangement, with a hydrogen atom attached to one of the oxygens.
Carbon monoxide is absorbed in the lungs and binds with the haemoglobin in our red blood cells. This reduces the capacity of the blood to carry oxygen. Here are the equations for the incomplete combustion of propane, where carbon is produced rather than carbon monoxide: propane + oxygen â carbon + water.
