MBA Corp plans to use its idle building that can potentially be rented for $15,000 per annum to set up a manufacturing machinery there. The current Revenue of MBA Corp is $500,000. If the company takes up this project, its revenue is expected to increase by 30% for the next three years and then double (from the 3rd year level) for the next two years. After 5 years, the project will be scrapped and the salvage value is expected to be $80,000 The COGS are expected to remain the same at 60% of revenue. The SG&A and other operating costs will increase by $10,000. The cost of the machinery is expected to be $250,000. The machinery installation cost is expected to be $20,000. This investment will require additional inventory of $40,000 and increase the accounts payable by $20,000 The company spent $ 5000 in researching the viability of the building for machine installation. The company hires you as a financial manager to advise if they should take up this project or not. Other information:…

4. CO hydrogenation to form CH4: CO + 3H2 →> CH4 + H2O occurs on a Ru/SiO2 catalyst and is used to remove traces of CO from H₂ streams used in fuel cell applications where ultra-high purity H₂ is required (even ppm levels of CO can poison fuel cells). This reaction occurs through the following steps: COCO* (1) (2) H2 + 2* 2 H* (3) CO* + * C* +O* (4) C* H* → CH*+* (5) CH* + H* → CH2*+* (6) CH2* H*. →> CH3*+* CH3* + H* → CH4 + 2* (8) O* + H* OH*+* (9) OH*+H* = H₂O+2* where Steps 1, 2, 3, 8, and 9 can all be considered quasi-equilibrated. What is the stoichiometric number of each step?

SpaceX recently launched their Falcon Heavy rocket (Feb. 6, 2018). It is based on their existing Falcon 9 rocket. The Falcon 9 rocket has a first stage which is a 40 m high by 3.7 m diameter cylinder. This cylinder contains the fuel used to propel the rocket which consists of RP-1 (rocket propellant-1, high grade kerosene), and liquid oxygen, O2 (`). RP-1 is a complex mixture of hydrocarbons but let’s approximate it with a chemical composition of C12H26. The densities of the fuel are ρ (RP − 1) = 0.83 g cm3 ρ (liquid O2) = 1.141 g cm3 If the total volume available for the two tanks is contained in the 40 m high by 3.7 m diameter first stage, determine the volume of each individual tank that will provide the exact amount of RP-1 and oxygen for the reation (no limiting reagent) and take up the entire volume of the first stage. Here are some suggestions to guide you. 1. Write a balanced combustion reaction for C12H26 with O2. 2. Determine the ratio of the volumes of the individual RP-1…
