S8 + 12O2 = 8SO3.Since there are 8 sulfur on the left, you must have 8 on the right, so 8SO3. Now you have 24 oxygen on the right, so you need 24 on the left. Multiplying O2 by 12 balances it.
This is a Composition Reaction (also known as Formation Reaction).... element + element ------> compound
This could never happen Hydrogen Peroxide is madeby the process known as the Riedl-Pfleiderer process, having been first discovered by them in 1936. The overall equation for the process is simple:H2 + O2 → H2O2The economics of the process depend heavily on effective recycling of the quinone (which is very expensive) and extraction solvents, and of the hydrogenationcatalyst.
The number written in front of a chemical formula is called the coefficient. This represents the number of molecules of the substance in the chemical formula. For example, 8SO3 tells you that there are 8 molecules of SO3 or sulfur trioxide.
