Why is concentrated sulfuric acid employed in the nitration of methyl benzoate reaction? What is the electrophile that is produced by the reaction of sulfuric acid and nitric acid?
lead(II) sulfide was once used in glazing earthenware. It will react with hydrogen peroxide to form lead (ii) sulfate and water. How many grams of hydrogen peroxide are needed to react completely with 265g of lead(ii) sulfide?
What mass in grams of CO2 was evolved? The balanced equation I set up is: Na2CO3 + 2HClO4 --> NaClO4 + CO2 + H2O Now what? What was the molarity of the excess reactant (HCl or Na2CO3)?
Can someone please explain to me in simple terms the 4n + 2 rule, and where\how the n integer is found
Explain why it is preferable to take the geometric mean rather than the arithmetic mean when defining mean activity
At 373 K, Keq = 2.39 for the following reaction: SO2Cl2(g) = SO2(g) + Cl2(g) In an equilibrium mixture of the three gases, the partial pressures of SO2Cl2 and SO2 are 3.31 atm and 1.59 atm, respectively.
