how many grams of potassium permanagate are needed to discolor 1 gram of 2-pentene in basic solution.
2 Al2O3(s) → 4 Al(s) + 3 O2(g) . ?H = +3339.6 kJ/mol What is ?H for the formation of one mole of Al2O3(s) from the elements?
A 100 mL buffer solution initially has 1.00 M HClO (Ka = 3.0 × 10-8) and 0.75 M NaClO. What is the new pH when this 100 mL of 0.10 M NaOH is added to the initial buffer solution?
Liquid sodium is being considered as an engine coolant. How many grams of liquid sodium (minimum) are needed to absorb 6.10 MJ of energy (in the form of heat)
Regiochemistry and stereochemistry in diels-alder reactions, How does one predict which regioisomer forms as the major product when more than one product can form? How does the dienophile affect the stereochemistry of the product?
Using the tools you have at hand (a melting point apparatus and TLC setup), what other data could you collect to test your hypothesis from part a? Give two possibilities.
what is the mole fraction of hydrogen in a gaseous mixture that consists of 8.00 g of hydrogen and 12.00 g of neon in a 3.5 liter container maintained at 35.20 degrees celsius?
How many molecules of actin can a muscle cell hold. Given: cell is spherical and has no other components with a diameter of 50 micrometers. Diameter of actin is 3.8 nanometers.
At 20 degrees C the vapor pressure of pure methanol (CH3OH) is 89.0 torr and of pure water (H2O) is 17.5 torr. A solution of methanol and water has a total vapor pressure of 52.9 torr at 20 degrees C.
Calculate the mass of AgNO3(s) that must be added to 0.500 L of a solution of 0.154 M NaClsolution to precipitate ‘all' of the chloride ion. The ‘all' means that we want to add the same number of moles of silver ion.
In N2O, nitrogen is the central atom and the oxygen atom is terminal. In OF2, however, oxygen is the central atom.Use formal charges to explain why.
A beaker contains 100 grams of 0.50 M NaCl. If you transfer 50 grams of the solution to anouther beaker, what is the molarity of the solution remaining in the first beaker?
