Explain the rate law for the solvolysis of benzyl bromide in 50% ethanol/50% water at room temperature (24C) is given by: rate = 2.9 x 10-5 (benzyl bromide)(OH-) + (benzyl bromide)Compute the percent of the reaction that takes place by each of the two nucleophilic substitution mechanisms (Sn1 and Sn2) whena) OH- = 0.500 Mb) OH- = 0.0005 Mc) Comment on your results:
a 45.0 g aluminum block initally at 28.0 celsius absorbs 825 joules of heat. what is the final temperature of the
calculate the activation energy for diffusion for a system where the diffusion coefficient doubles its value from 700k to 1200k. R=8.314J/molk.
Describe: a) its use in medical treatment, b) list a common over the counter medicine that once contained this compound and c) why phenolphthalein is being phased out in over the counter medicine formulations
Write a balanced chemical equation for the standard formation reaction of gaseous hydrogen cyanide
A sample consisting of 3.0 mol of ideal gas molecules at 200K at 2.00 atm is compressed reversibly and adiabatically until the temperature reaches 250K.
Glass tempering can be accomplished by both thermal and chemical means. Each puts the near surface region of the glass piece into compression, thereby suppressing growth of surface cracks.
What is the minimum uncertainty in the position of an electron, given that we know nothing about its speed except that it is less than the speed of light?
In a sample containing small grains of sand, what would you observe in the Mel-Temp apparatus when you melt the sample that would indicate to you that your sample contained this type of impurity
A chemist wants to prepare 0.48 M HCl. Commercial hydrochloric acid is 12.4 M. How many milliliters of the commercial acid does the chemist require to make up 1.48 L of the dilute acid?
double bond energy= 837 h single bond cl = 431 C single bond C = 347 C single bond H = 414 C single bond Cl 339 It says answer is -154 kJ but im not getting that
Utilize 4-Methylcyclohexanol plus an acid (H3PO4) also heat to synthesize 4-Methylcyclohexene + H2O. Get a good percent yield. Does this reaction take place via and E1 or an E2 pathway
