Write balanced reaction equations for the two steps in the synthesis of 2-butoxynaphthalene.
At a higher temperature, 373K, dinitrogentetraoxide partially decomposes according to the same equilibrium reaction but with slightly different results. The chemical equation is again
What are the other other concentration units. 1. mass percent 2. mass of H2SO4 in 1 L 3. mass of 1 L 4. mass percent 5. kg H20 6. molality 7. mole fraction H2SO4
A sample of gasoline contains various hydrocarbons, which comprise atoms of carbon, hydrogen, and oxygen. The hydrocarbons mix together uniformly to form gasoline. Which term or terms could be used to describe this sample of gasoline?
how many grams of oxygen are produced. what are the limiting and excess reactants and how much ER remains
What is the osmotic pressure associated with a 0.0200 M aqueous solution of a nonvolatile nonelectrolyte solute at 75C
What is the relative kinetic energy between the electron and proton after ionization, that is r=infinity? C) Assume that the electron has all the kinetic energy in part
What is the pH of this solution? What is the concentration of the molecular species H3PO4?
how do you find the concentraton of an isotope from its molarity and molecular weight with no other factors
Hydration of alkynes (via oxymercuration) gives good yields of single compounds only with symmetrical or terminal alkynes. Draw the major organic product(s) formed when hex-2-yne undergoes hydration in the presence of HgSO4 and H2SO4.
a method for the determination of copper yields results that are too low by 0.47mg. What will be the percent relative error due to this source if the weight copper in a sample is 45.3 mg
When ethyl benzoate is heated in methanol containing a small amount of HCl, methyl benzoate is formed. Draw structural formulas for the first two intermediates in this reaction.
If 0.20g of gas occupies 400 mL at 30 degrees celsius and 700 mm Hg of pressure, what is the molar mass of the gas?
