To start with, you can place a coefficient of 2 in front of H2O to balance out the oxygen, giving: H2S + 3O2 → 2H2O + SO2. For example, C6H5C2H5 + O2 = C6H5OH + CO2 + H2O will not be balanced, but XC2H5 + O2 = XOH + CO2 + H2O will. In many cases a complete equation will be suggested. Sporen) und ist damit ein hervorragendes Biozid. Hydrogen is now out of balance, so a coefficient of 2 can be placed in front of H2S to give: 2H2S + 3O2 → 2H2O + SO2. in the first step when you split it apart into Au 2CN- --> Au(CN)2 ^-1 how many electrons do you add?
