This mass loss of 0.1866 g for each mole of 235U reacting corresponds to 7.94 x 10-4 g per 1 gram of 235U fuel reacting. The energy released is calculated from E = mc2, where m is the mass loss in kilograms, c = 2.998 x 108 m/s, and energy has units of joules. How much energy does 1 gram of 235U fuel produce?
The laser beams are tightly focused. They briefly (for 0.5s) exert enough pressure to confine 500sodium atoms in a vloume of 1.0x10^-15m^3. The temperature of this gas is 0.00024K, the lowest temperature ever reached for a gas. Compute the root-me..
What pressure is exerted by a sample of nitrogen gas of mass 3.055 g in a container of volume 3.00 dm^3 at 32 degrees C
what may happen to a large i.e. 30-50lb container of trichloro-s-triazinetrione or calcium hypochlorite if it is left
How would you go about seperating camphor and melezitose when you only have a solvent of water and benzene
Silver Chloride, frequently used in silver plating, contains 75.27% Ag. Compute the mass of silver chloride required to plate 255mg of pure silver.
If the activation energy of a reaction reduces from 100 kJ/mol to 90 kJ/mol at 298K by what factor will the rate of reaction change
What is the partial pressure of H2O in the compressed gas mixture? (See this table.) torr (b) What mass of water vapor condenses to liquid g
Use the pKa cata to help you predict the products of the reactions. Use curved arrows to show electron flow. Predict whether the equilibrium lies to the left or to the right and calculate the equilibrium constant for the reaction.
Assuming the same mass of each, which of the following substances will have the highest temperature change if they all absorb the same amount of heat Gold
According to Hund's Rule, how many unpaired electrons are in the valence shell of element 10?
A student synthesized benzyl acetate following Fischer esterification, and combined 3.4 mL benzyl alcohol (MW = 108.14 g/mol, ?= 1.044 g/mL) and 0.57 mL acetic acid (MW = 60.05 g/mol, , ?= 1.049 g/mL) under reflux for 50 minutes.
