Use Coulomb's law to compute the ionization energy in kj/mol and the wavelength of an atom composed of a proton as well as an electron separated by 117.00 pm?
Compound (CH3)2CCHCH3 contains 85.63 g carbon per 100.0 g compound. Calculate the mass (g) of a sample of (CH3)2CCHCH3 if it contains 148.9 g of carbon.
How many grams of O2 will be required to completely react with 2.43 grams of Mg metal ribbon to produce MgO.
How much heat energy, in kilojoules, is required to convert 68.0 grams of ice at -18.0 degrees C to water at 25.0 degrees C
According to the following reaction, how many grams of silver chloride will be formed upon the complete reaction of 28.4 grams of copper(II) chloride with excess silver nitrate
Treatment of ethyl isobutyrate with ethoxide in ethanol, followed by mild acidic workup, leads to recovery of starting material rather than a Claisen Condensation product. Please explain this observation, using structures rather than words as much..
A solution was prepared by dissolving 0.450 g MgSO4 (FW=120.363g/mol) in 0.500L of water. A 50.0 mL aliquot of this solution consumed 37.60 mL of EDTA solution in a titration.
1.0 mol of CaCN2 and 1.0 mole of water are mixed together: CaCN2 + 3 H2O → CaCO3 + 2 NH3 How much NH3 could be produced?
After the reaction was complete, nitric acid was added to dissolve the AgSO3 but not the AgSe. The Ag+ from the dissolved Ag2SeO3 and the excess reagent required 16.74mL of 0.01370 M KSCN in a Volhard titration. How many milligrms of Se were conta..
