Calculate the neutron separation energy for 16O8 and 17O8

Given:

Vapor–liquid equilibrium data in mole fractions for the system
acetone–air–water at 1 atm (101.3 kPa) are as follows:

Find:

(a) Plot the data as (1) moles acetone per mole air versus moles
acetone per mole water, (2) partial pressure of acetone versus g acetone
per g water, and (3) y versus x. (b) If 20 moles of gas containing
0.015 mole-fraction acetone is contacted with 15 moles of water,
what are the stream compositions? Solve graphically. Neglect water/
air partitioning.

An elementary reaction A to B is reversible and has an equilibrium constant of 10, and a forward rate constant of 1.0 d^-1.

a) Plot the concentrations of A and B as a function of time in a batch reactor that initially contains 10^-3 M each of A and B. Show the data from the initial condition until the concentrations are both changing at an instantaneous rate of less than 10^-5 M per day.

b) Repeat part (a) if the initial concentrations are 2 x 10^-3 M of A and no B.

c) What are the molar concentrations of A and B at equilibrium in part (b)?

Larson (1964) measured the diffusivity of chloroform in air at 298 K and 1 atm and reported its value as 0.093 cm2/s. Estimate the diffusion coefficient by the Wilke-Lee equation and compare it with the experimental value.

a) why can noble gases bond with other atoms under certain conditions?

b) why does MgO fail in a brittle manner even though the crystal structure of MgO is FCC?

The inner surface of a 5 cm diameter, 3 mm thick, and 7 cm high styrofoam cup is at 70 °C. the outer surface is exposed to air at 20 °C. the surface heat transfer coefficient associated with the outer surface is 8 w/m² °C. Determine

The heat transfer rate through the cylindrical surface of the cup.

The outer surface temperature of the cup.

Material Science

Select one new material being developed for emerging needs of technology. Describe why this material is suitable for this application. The reasons must be discussed in terms of the required properties and the ability to process(make) the material from raw material. Also discuss why the required properties are possible based on the atomic structure and bonding

1 kmol/h of a feed stream containing 15, 45 and 40 mol% of nitrogen, n-butane and n-pentane at 500 ºC and an unknown pressure, is cooled isobarically to a temperature of 105 ºC and fed into a flash drum operating at the same temperature (105 ºC) and pressure. If the vapor fraction V/F in the drum is equal to 0.5, determine the pressure at which the flash drum operates, and the flow rates and composition of both streams leaving the drum. Suggestion: to find the range of possible pressures, first determine the bubble and dew pressures of the mixture at 105 ºC. Here you would need to submit (1) an Aspen Plus Document file (i.e., GroupXX_Problem2.apw) with your final solution, and (2) a short file/write-up explaining how you solved this problem.

Use HYSYS to solve a simple energy balance.

Mixing a cold water stream (120 kg/min 30C) and a hot water stream (175 kg/min 65 C) then heating the streams to saturated vapor at 17 Bar. What is the duty?

Suppose you have Avogadro\'s number of mini marshmallows and use them to cover the state of Oregon which has a land area of 9.600 × 104 mi2. Each mini marshmallow has a diameter of 0.635 cm and a height of 2.54 cm. Assuming the marshmallows are packed together so there is no space between them, to what height above the surface, in kilometers, will the mini marshmallows extend?

Material Safety Data Sheets or Safety Data Sheets (MSDS/SDS) – The Worker’s Right to Know Law grants employees the right to know the hazards of all chemicals in their work place. These hazards can be found in the MSDS or SDS forms that employers are required to maintain for all hazardous chemicals used at the facility. MSDS and SDS are very similar, but the latter is an updated version designed to increase consistency.

MSDS/SDS: (10pts) (need word file) and post the sources where to find that information

Sources of MSDS/SDS: (1pt)

1, What is the definition of LD₅₀? Identify the source of this definition. (1pt)

2. Assuming that these compounds are similarly toxic to humans, how much of each compound would be required to reach the LD₅₀ for a 150 pound human? Show your calculations. (4pts)

3. Which of the two compounds is more toxic? How can you tell? (2pts)

4. What are the acute effects of exposure for each compound? (1pt)

5. What does the MSDS/SDS recommend be done if each compound is ingested? (1pt)
