A piston has an external pressure of 14.0 . How much work has been done if the cylinder goes from a volume of 0.180 liters to 0.650 liters.
Water gas a mixture of h2 and co2 is a duel made by reacting steam with red hot coke ( a by product of coal distillation):
A 28.7 g sample of ethylene glycol, a car radiator coolant, loses 652 J of heat. What was the initial temperature of ethylene glycol if the final temperature is 32.5°C (c of ethylene glycol = 2.42 J/gK)
the sample has a mass of .211 grams,a volume of .25 and a temperature of 275K at a pressure of .945 atmospheres. What is the most likely element forming the sample?
Using the Boltzmann distribution given below, determine Jmax (quantum number of the most intensely populated rotational state) as a function of temperature. Then find Jmax for CN+ at 298 K and 1100 K.
4.60 mol of solid A wasplaces in a sealed 1.00 L container and allowed to decompose into gaseous B and C. The concentration of B steadily increased until it reached 1.10M where it remained constant.
Assuming 100% dissociation, calculate the freezing point and boiling point of 3.27 m AgNO3(aq). Constants may be found here.
The smallest sample of carbon atoms that can be observed with the naked eye has a mass of approximately 2 x 10-8 g. Given that 1 g = 6.02 x 1023 amu,
15.73 grams of a solution containing 8.43% acetic acid, HC2H3O2, is mixed with water and titrated with a 0.523 M solution of KOH. How many milliliters of the KOH solution are required to reach the equivalence point?
The polymerization rate DP are proportinal to the first power of monomer concentration. What would be the effect of monomer concentration on DP in the thermal polymerization of styrene?
For the best system, calculate the ratio of the masses of the buffer components required to make the buffer
A chemist has isolated a new natural product and determined its molecular formula to be C24H40O4. In hydrogenation experiments the chemist found that each mole of the natural product reacted with two moles of H2. How many rings are present in the ..
