When most Fe3+ salts are dissolved in dilute nitric acid, the solution is often yellow to orange-yellow in color. Why could you not visually detect these colors in the Fe(NO3)3 stock solution?
Suppose the pH of the water is 3.88 and that the concentration of iron(II) in the water is 2.30x 10-5 M, what is the potential of the corrosion reaction under the above conditions at 298 K?
What volume of hydrogen can be produced at 22.0C and 1.01atm pressure by the reaction of 25.0ml of 2M HCL with 0.3g Zn?
Ammonia is made industrially by reacting nitrogen and hydrogen under pressure, at high temperature, and in the presence of a catalyst. The equation is N2(g)+3H2(g)---->2NH3(g). If 4.0mol of H2 react, how many moles of NH3 will be produced.
8.20 grams of solute in 861 grams of water lower the freezing point to -0.430 degree celsius calculate the molecular mass of the nonionic solutes.
Draw the molecule by placing atoms on the grid and connecting them with bonds. Do not identify the charge on each of these species. Include all lone pairs of electrons.
63.0 mL of a 1.20 M solution is diluted to a volume of 208 mL. A 104-mL portion of that solution is diluted using 157 mL of water. What is the final concentration.
A sample of carbon monoxide gas whose mass is 7.75 g is heated from 25 oC to 166 oC at a constant pressure of 5.52 bar.
Use the Nernst Equation to calculate Ecell at 25 C for electrolysis of aqueous sodium chloride if the concentration of chlorine in the brine solution is 4.5 M and the partial pressure of Cl2 is 0.001 atmospheres.
A 13.74 gram sample of an organic compound containing C, H and O is analyzed by combustion analysis and 20.49 grams of CO2 and 6.291 grams of H2O are produced.
