The thiosulfate ion (S2O32-) and the dithionite anion (S2O42-) are two other sulfur containing reducing agents. What are the oxidation states of sulfur in the two ions?
Twenty-five tons of coal that is 3.6% sulfur by mass is burned at an electric power plant. During the combustion of the coal, the sulfur is converted into sulfur dioxide. How many tons of sulfur dioxide are produced
At what pH would the given concentrations of Ce4+ (1.67*10^-4), Ce3+ (.185), Mn2+ (1.28x10^-5) and MnO4- (.148) be in equilibrium at 298 K. Chemical equation is 5Ce4+ + Mn2+ 4H2O => 5Ce3+ + MnO4- + 8H+. And E standard is .193V
The level of liquid kerosene rises from 8.5 ml to 15.3ml. Calculate the density of the solid and identity the compound from the following list.
