When aluminum is added to a strong acid, the metal is oxidized to aluminum (III) ions by hydrogen gas and H+ is formed. If 10.0 g of aluminum is added to the 50.0 mL of 0.450 M HCl, determine the concentration of Al3+ in the moles moles/
Explain what would be the atomic mass of Cl? Chlorine has two stable isotopes of mass 34.97 u and 36.97 u. Suppose the percent abundance of the lighter isotope were 62.41%.
It is suggested that SO2 (molar mass 64grams), which contributes to acid rain, could be removed from a stream of waste gases by bubbling the gases through the 0.25-molar KOH, there by producing K2SO3.
If the rock contained no carbonate other than CaCO3, what was the percent of CaCO3 by mass in the limestone? When a 1.25-gram sample of limestone was dissolved in acid, 0.44 gram of CO2 was generated.
Briefly explain how you could use thin layer chromatography to decide when the reaction was complete. Suppose you prepared benzhydrol by the reduction of benzophenone with sodium borohydride.
Determine the minimum volume of the acid solution needed to react with all of the iron? Iron reacts with HCl solution to give Fe2+ ions and H2 gas. Suppose that 7.1 g of iron are to be dissolved in the 1.3 M HCl.
Determine the maximum theoretical percent recovery from the re-crystallization of 1.00g of benzoic acid from the 15 ml of water, assuming the solution is filtered at 25 degrees C.
Aluminum does not have magnetic properties and heating up the two will destroy the plastic. So, is it possible to separate the plastic and aluminum without picking the pieces out by hand?
