Why does crotyl chloride react faster than 1-chlorobutane in ethanol, since both are primary alkyl halides?
You set out to design a car that uses the energy stored in a flywheel consisting of a uniform 97-kg cylinder of radius R that has a maximum angular speed of 330 rev/s. The flywheel must deliver an average of 1.70 MJ of energy for each kilometer of distance. Find the smallest v...
the density of H2 gas in a rigid container is 0.117 g/L at 55 C. what is the pressure of hydrogen in the flask if it is heated to 125 C?
Draw a flowchart for a program that reads a date in an 8-digit sequence (month, day, year) and determines if the date is a valid date. ignore leap year. Assume Feb has 28 days, and establish a table of days in a month so that you can access the appropriate month to determine t...
A 15.0ml sample of NaCL solution has a mass of 15.78g.after the NaCL solution is evaporated to dryness, the dry salt residue has a mass of 3.26g. calculate the following concentrations for the %(m/m), % (m/v), molarity (M)
DES and AES are both turn the handle algorithms, in that they use repetition of some number of very similar cycles. What are the advantages to implementer, users, cryptanalysts of this approach?
Julie is solving the equation x2 + 6x + 9 = 0 and notices that the discriminant b2 - 4ac has a value of 0. This tells her that the equation has
how are the ionization energies evidence for the structure of the atom especially the electron configurations for atoms ?
thanks but my instrutor dont want me to use energy to solve the problem since we havnt learn it yet, can you do it using newton's law?
A block of mass M is projected up a frictionless inclined plane with a speed VO. The angle of incline is given as theta. a. How far up the plane does it go? b. How much time does it take to get there? I was stuck after Fg(cos(theta+90)= Ma_x gcos(90+theta)/M = a_x can someone ...
