An equilibrium mixture of SO2, O2, and SO3 at a high temperature contains the gases at the following concentrations: [SO2] = 3.77 × 10-3 mol/L, [O2] = 4.30 × 10-3 mol/L, and [SO3] = 4.13 × 10-3 mol/L. Calculate the equilibrium constant, Kc, for the reaction.2 SO2(g) + O2(g) à 2 SO3(g)
Write balanced half-reactions and the overall spontaneous reaction. (Type your answer using the format [NH4]+ for NH4+. Use the lowest possible coefficients.)
The Born-Haber cycle is a series of steps that represent the formation of an ionic compound from a metal and a nonmetal. For example, the steps in a Born-Haber cycle for the formation of NaCl(s) consist of sublimation of the metal Na atom
A 21.8 g sample of ethanol (C2H5OH) is burned in a bomb calorimeter, according to the following reaction. If the temperature rises from 25.0°C to 62.3°C, determine the heat capacity of the calorimeter. The molar mass of ethanol is 46.07 g/mol.
For a particular redox reaction MnO2 is oxidized to MnO4- and Cu2 is reduced to Cu . Complete and balance the equation for this reaction in basic solution.
Heatite, Fe2O3 is an important ore of iron, the free metal is obtained by reacting hematite with carbon monoxide in a blast furnace. carbon diozide is formed in the furnace by paritial combustion of carbon, the reaction is Fe2O3 (s) + 3 CO (g) -->..
He concluded that electrons are emitted only when intensity of light is increased. He observed a continuous spectrum of light when hydrogen gas was supplied with energy.
Problem- What is the chemical equation for the above? Is there a reaction? If so, what are the balanced 1) molecular, 2) ionic, 3) net ionic equations? What are the states in the net ionic equation?
