russ_watters said:You need to ratio the weights of the constituent parts of water. How much does a hydrogen atom weigh? How much does an oxygen atom weigh?
The decomposition of water occurs through a chemical reaction where water (H2O) is broken down into its component elements, hydrogen gas (H2) and oxygen gas (O2).
The rate of water decomposition can be affected by temperature, presence of catalysts, and concentration of reactants.
The decomposition of water is an endothermic reaction, meaning it requires energy to break the bonds between the hydrogen and oxygen atoms.
The amount of oxygen gas formed can be determined through stoichiometric calculations, using the molar ratios between water and oxygen in the chemical equation for the decomposition reaction.
Water decomposition is used in industries such as hydrogen production and fuel cells. It is also a key process in photosynthesis, where plants use energy from sunlight to decompose water and produce oxygen for the Earth's atmosphere.
