/in /by

    1. A chemical system within a sealed 1 L reaction vessel is described by the following reversible reaction equation:

      2H2S(g) <–>2H2(g) + S2(g)

      If the equilibrium constant is 0.000 004 200 at 1103 K find:

    2. the reaction quotient initially.
    3. the order of concentration of all three components at equilibrium (greatest concentration to lowest) without using calculations.
    4. what the size of the reaction quotient indicates regarding the extent of the forward reaction.
    5. the equilibrium concentration of sulphur gas if 0.070 mol of hydrogen sulphide gas is initially placed in the vessel.

Note: for part d you may make the simplifying assumption that the amount of hydrogen sulphide gas reacted is extremely small in relation to the initial amount of hydrogen sulphide gas—this will allow you to avoid a quadratic expression in the denominator of the reaction quotient by disregarding one term).

Dakota trucking company is evaluating a potential lease for a truck

/in /by

“Dakota Trucking Company (DTC) is evaluating a potential lease for a truck with a 4-year life that costs $40,000 and falls into the MACRS 3-year class. If the firm borrows and buys the truck, the loan rate would be 10%, and the loan would be amortized over the truck’s 4-year life, so the interest expense for taxes would decline over time.

The loan payments would be made at the end of each year. The truck will be used for 4 years, at the end of which time it will be sold at an estimated residual value of $10,000. If DTC buys the truck, it would purchase a maintenance contract that costs $1,000 per year, payable at the end of each year.

The lease terms, which include maintenance, call for a $10,000 lease payment (4 payments total) at the beginning of each year. DTC’s tax rate is 40%.

Should the firm lease or buy?

What is the Net Advantage of Leasing (if any)?”     

Your company has assigned you to work on a project plan for a new

/in /by

Your company has assigned you to work on a project plan for a new internal support system.
This system will be expected to track formal contacts between company software contracting teams,
internal management sponsors, and their external clients. In addition to the technical aspect of the
project, there is significant doubt surrounding how well the project teams and the external clients will
accept the changes mandated by the use of the new system, and what factors will impact its
effectiveness.
Your assignment is risk control planning.
In 3-5 pages, complete the following:
Produce a risk register.At a minimum, each risk must be assessed qualitatively.Provide a memorandum detailing in-depth assessment of one of each of the four recognized types of
risk control measures.
