1 -Can you show that the fusion reactions can release enough energy to feasibly power a star ?Assume atomic weight of H = 1.008172 amu and He4 = 4.003875 amu.2- what is the mean distance between particles in the sun ?? Does it justifies the assumption of an ideal gas ??
A solution is prepared by mixing 0.0400 mol CH2Cl2 and 0.0800 mol of CH2Br2 at 25°C. Assuming the solution is ideal, calculate the composition of the vapor (in terms of mole fractions) at 25°C. At 25°C, the vapor pressures of pure CH2Cl2 and pure CH2Br2 are 133 and 11.4 torr, respectively.

A 1,480-N crate is being pushed across a level floor at a constant speed by a force of 280 N at an angle of 20.0° below the horizontal, as shown in the figure (a) below.
What velocity must a car with a mass of1110 kg have in order to have the same mo-mentum as a 2160 kg pickup truck travelingat 27 m/s to the east?Answer in units of m/s
Consider a mixture of air and gasoline vapor in a cylinder with a piston. The original volume is 40. cm3. If the combustion of this mixture releases 925 J of energy, to what volume will the gases expand against a constant pressure of 675 torr if all the energy of combustion is converted into work […]
