a. Draw the structures of phthalic anhydride, ethylene glycol, and glycerol. b. Draw the polymer that results from phthalic anhydride & ethylene glycol. c. Draw the polymer that results from phthalic anhydride and glycerol. d. Are these addition or condensation polymers? e. Describe and explain the differences between the polymers formed from the reaction of phthalic anhydride with ethylene glycol versus phthalic anhydride with glycerol.
What is the molecular formula for the compound containing 30.4% nitrogen and 69.6% oxygen by mass and having a molar mass of 92.0 g?
Write three orbital designations that would be incorrect and explain why each is incorrect. For example, 1p would be an incorrect orbital designation because there is no p sub-shell in the first orbit.
what is the total number of liters of O2 at STP needed to produce 6.0 times 10^23 molecules of H2O.
If you have 24.0 g of NaCl dissolved in 306 mL, what is the molarity of the solution
What is the value of the rate constant (k) for this reaction? Points will be deducted if you do not include the correct sign and units of the rate constant. (b) Determine the half-life for this reaction in units of seconds
calculate the volume, in liters, occupied by 3.25 moles of Cl2 gas at 1.54 atm pressure and a temperature of 213 degrees celcius?
Determine the molarity of a solution that is formed by dissolving 21.0 g of CaF2 in a flask and adding water to make 446.2 mL of solution
A 500 L tank contains 525 moles of propane at 100°C. The critical point for propane is 369.9K and 42.0 atm. Calculate the tank pressure (absolute) using the Virial Equation (1st order). Note: ? = 0.152 for propane.
what is the mass in grams of 17.55ml of acetone? and what is the volume in milliter of 7.26g of acetone?
The product is a cyclopentyl ether (five carbons with an oxygen). Then attached to a carbon directly adjacent to the oxygen is a methyl bromide group.
A new catalyst is being developed with the hope of generating ethylene by the oxidative dehydrogenation of ethane, reaction (1). Two side reactions accompany the main reaction;
a) water is sprayed on the ground of an orchard when temperatures are near freezing to keep the fruit from freezing. Explain b) How many kilojoules of energy are released if 5.0 kg of water at 15 degrees C is on the ground and cools and freezes at..
