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.
The reaction S8 + 12O2 → 8SO3 is a combustion reaction. It involves the rapid combination of sulfur and oxygen to produce sulfur trioxide with the release of heat and light.
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 a coefficient. It represents the relative number of molecules or formula units of each substance in a chemical reaction. It is used to balance chemical equations by ensuring that the same number of each type of atom is on both sides of the equation.
