Compare the stability of two conjugated dienes, and two nonconjugated dienes, each with the formula C7H12 and the base name hexane. Which type is the most stable and which is the least stable according to your data? For one of the conjugated dienes, determine the bond lengths of each C-C single bond. Indicate which is the shortest and explain why it is using a resonance structure
Identify the likely kinds of intermolecular forces in the following substances: HCL , CH3CH3, CH3NH2, Kr
Suppose that 25 g of each of the following substances is initially at 28.0degrees C. What is the final temperature of each of the following substances upon absorbing 2.35 kJ of heat.
We had this experiment where we took 4-bromo-N-ethanoylbenzeneamine and we refluxed it with HCl to achieve hydrolysis. We then added enough NaOH to render the solution pH 8. We then distilled the mixture in steam to yield 4-bromoaniline. Why was t..
a 70g piece of ice at 0c is added to a sample of water at 6c, all of the ice melts and the temp of the water decreases to 0c, how many grams of water were in the sample?
What are the mass and mole fraction of all components in the mixture? What is the average molecular weight of the mixture?
A patient is given 0.055mg of technetium -99m, a radioactive isotope with a half-life of about 6.0 hours.
A gas is heated from 268 K to 290 K while its volume is increased from 25.0 L to 37.0 L by moving a large piston within a cylinder. If the original pressure was 0.90 atm, what would be the final pressure?
Chlorine gas can be prepared in the laboratory by the reaction of manganese dioxide with hydrochloric acid. How much MnO2 should be reacted with excess HCl to obtain 275 mL of chlorine gas at 5.0 °C and 650 mmHg?
How many mL of 0.250 M NaOH are needed to completely saponify 240. g of of glyceryl trioleate (triolein)?
In testing for the efficacy of an antacid compound, 5.00 g of hydrochloric acid is mixed with 24.0 g of magnesium hydroxide. Is this enough base to react with all of the acid
