When a nucleus of 240^Pu undergoes fission, it breaks into two smaller, more tightly bound fragments.
Calculate the binding energy per nucleon for 240^Pu.
Calculate the binding energy per nucleon for the fission product 133^Xe.
A student determined the Ca^2+ ion content of a 100 mL sample of calcium-fortified orange juice. After adding 2.0 M HCl solution to the sample, the student filtered the juice to remove the pulp and other particulate matter.
The temperature of a sample of water increases by 6.5 degrees Celsius when 8.5 kilo Joules are applied. The specific heat of liquid water is 4.18 Joules per gram x degrees Celcius. What is the mass of the sample of water?
The vapor pressure of dichloromethane,CH2Cl2, at 0 C is 134 mmHg. The normal boiling point of dichloromethane is 40 C. Calculate its molar heat of vaporization.
The random walk model used to describe gas diffusion can be treated as a binomial distribution similar to coin flips with a 50/50 chance that a particle will move in either the +x direction or the -x direction.
The molar enthalpy of vaporization of water is 44.012 kJ mol-1. Under an applied pressure of 1 atm, water boils at 373.15 K. The safety value of a kitchen pressure cooker is set to release when the pressure reaches 2 atm
What is the molar mass if a 0.550-g sample occupies 258mL at a pressure of 744 torr and a temperature of 22 degrees C
Calculate the molar solubility of Mg(OII)_2 in a solution with a pH of 12.8 (K_op of Mg(OH)^2 is 1.2 * 10^-11
A solution gave a precipitate when ammonium oxalate was added but gave no precipitate when ammonium sulfate was added. For each Magnesium group ion(Barium, Magnesium, Strontium, and Calcium) tell whether the ion
A piece of indium with a mass of 16.6 g is submerged in 46.3 cm3 of water in a graduated cylinder. The water level increases to 48.6 cm3. The correct value for the density of indium from these data is
if a 189-mg piece of gold density 19.32 gcm3 is hammered into a sheet measuring 2.4 ft 1.0 ft what is the average
If 200 mL of 0.300 M Cr(NO3)3(aq) is added to 100 mL of 4.0 × 10^-4 M NaF(aq) at 25 degrees celcius, will a CrF3 precipitate form? For CrF3 in water at 25°C, Ksp = 6.6 × 10^-11.
Calculate the mass of 5.00mL of water using the date from all members of group. these numbers are the ones from my group 24.601g 28.8107g 29.4162g 29.2040g
