Calculate the wavelength in nanometers for an electron that has been accelerated from rest through a potential change of 500V. I know that phtoeletric effect equation(KE=0.5mv^2)is involved but I would like a detailed explanation of the solving process.
combustion of 1.96g of a compound containing only hydrogen and carbon produced 6.35g of co2 and 2.25g of h2o. the
When 9.6 g of an unknown non-electrolyte is dissolved in 50.0 g of carbon tetrachloride, the boiling point increased to 80.43 degrees C from 76.5 degrees C. If the Kbp of the solvent is 4.95 K/m, calculate the molar mass of the unknown solute.
a hydrogen-filled balloon was ignited and 1.50 gram of hydrogen reacted with 12.0 g of oxygen. how many grams of water
You react an excess of hydrogen gas with 8.00 get of oxygen gas to format water. what mass of water is formed, assuming a complete reaction?
What is the maximum number of moles of KClO3 that could form in the combination of 6.0 moles of Cl2 with 9.0 moles of KOH? Balanced equation is 3 Cl2 + 6 KOH goes to KClO3 + 5 KCl + 3H2O
The Ksp of AgCl at 25oC is 1.0 x 10^-10. Calculate the concentrations fo Ag+ and Cl- in a saturated solution of AgCl, and the molar solubility of AgCl.
Calculate the mass of sodium hydroxide that must be added to 1.00 L of 1.00 M HC2H3O2 to double the pH of the solution (assume that the added NaOH does not change the volume of the solution). Ka of HC2H3O2 = 1.8 x 10 ^-5
Give the molecular formula of ammonium iodide. Which kind of compound is HClO2: ionic, molecular, acid or hydrate? Give its name.
Reaction of p-aminophenol with acetic anhydride to produce acetylaminophenol, In an experiment, acetylaminophenol is produced from the reaction of p-aminophenol with acetic anhydride.
if I have .42N NaOH and the stoiometry between Oxalic acid and Naoh is 1:2 then does that mean i do .42/.5=mol Oxalic acid * vol of titrations = molarity of oxalic acid
5H2C2O4 + 2KMnO4 --> 10CO2 + K2SO4 + 2MnSO4 + 8H20, How many g of H2SO4 are required to produce 75g of CO2
