Metallic iron can be made by the electrolysis of molten Fe2O3. How many minutes are needed to plate out 14.00 g of Fe from molten Fe2O3 using 6.42 A current? Use F = 96,500 C/mol for Faraday's constant. The unbalanced chemical reaction representing this electrolysis is shown below: Fe2O3 Fe + O2
Calculate the pH for each of the following cases in the titration of 50.0 mL of 0.220 M HClO(aq) with 0.220 M KOH(aq). The ionization constant for HClO
Sketch a cylinder with ten molecules of helium (He) gas. The cylinder has a movable piston. Label this sketch before. Make an after sketch to represent
Helium is collected over water at 25°C and 1.00 atm total pressure. What total volume of gas must be collected to obtain 0.563 g of helium? (At 25°C the vapor pressure of water is 23.8 torr.)
The nitrate ion reaction is positive. In this case, is it accurate to state that nitrate ion was present in the original solution? Brie?y explain, referencing specific chemical reactions to support your explanation.
gas expand isothermally and reversibly from 10 bar to 1 bar at t= 25 celcius. calculate q,w, delta u,h,s,a,g. please show how u got the equations
Calculate the molality and molarity of an NH3 solution made up of 37.0 g of NH3 in 70.0 g of water. The density of the solution is 0.982 g/mL.
The vapor pressure of a liquid is the pressure exerted by its vapor when the liquid and vapor states are in equilibrium. The relationship between vapor pressure and temperature is expressed by the Clausius-Clapeyron equation.
