In the analysis of 1.5000g sample of feldspar, a mixture of the chlorides of sodium and potassium is obtained which  weighs 0.3450g. Here is the full equation: SO4-2 + 2 CH2O + 2H > H2S + 2CO2 + 2H2O, O is -2 and you have 2H both at +1, so C is +2 in this case. The thermal decomposition of formaldehyde, CH2O, produces CO and H2, not CO2. Should I call the police on then? What is the oxidation number of C in CH2O. I know O is -2 and H is +1 unless there is a metal which there isnt so anything you put for C would unbalance the compound no? Join. The chief was seen coughing and not wearing a mask.
