A 50 gram ball is thrown at a wall and bounces off. Its speed just before impact is 24 m/s and its speed just after hitting the wall is 22 m/s in the opposite direction. If the ball is in contact with the wall for 3.5 ms, what is the magnitude of the average acceleration of the ball while it is in contact with the wall?
When the satellite reaches the position m, its speed is 6.17 m/s. How much work did your friend do?
Consider the six pz orbitals on carbon atoms (the pi system) of the benzene molecule (D6h symmetry). These may be treated as vector arrows pointing vertically above the plane of the six-membered ring.
Question- The equilibrium constant kc for the decomposition of phosgene, COCl2, is 4.63 X 10-3 at 527 degrees C. Calculate the equilibrium partial pressure of all the components, starting with pure phosgene at 0.760 atm
the osmotic pressure generated was 6.65atm at 298K. The compound was also found to be nonvolatile and a non-electrolyte. What is the molecular weight they determined for this compound.
A mixture of CO(g) and O2 (g) in a 1 L container at 1000 K has a total pressure of 2.2 atm. After some time the total pressure falls to 1.9 atm as the result of the formation of the CO2(g). Find the mass in grams of the CO2 gas.
Using 1-butanol as the only organic starting material, write out a series of reactions that will produce this molecule:
Recall that the volume of a sphere is given by the formula (4/3) pr^3 and the density of lead is 11.3 g/cm^3.
Osteo imperfecta displays a wide range of symptoms for mild to servere. On the bases of amino acid and collagen structure,
The equilibrium constant of H2 combustion at 1500K surpass that of N2 combustion at 2200K by at least 2 orders of magnitude.
Question- A sample of octane in equilibrium with its vapor in a closed 1.0 L container has a vapor pressure of 50 torr at 45ºC. The container's volume is increased to 2.0 L at constant temperature and equilibrium is re-established. What is the va..
