A vapor mixture of -butane (B) and -heptane (H) contains 40.0 mole% butane at 80°C enters a condenser at a rate 4 kg/s. Liquid and vapor product streams emerge from the process in equilibrium at 40◦C. The vapor product has a 45.0 mole% butane composition. Determine: a. The pressure in the condenser b. The composition and flowrate (mol/s) of the liquid stream c. During operation, the system contains a 3m depth of the liquid phase (S.G. = 1.41) at any given time. If the maximum pressure the vessel floor joints can handle is 1 bar, will the tank rupture?

Background
As seen on this picture of the cosmic microwave background (take from the Wikipedia entry on the very same topic) there exists irregularities in the distribution of matter: Cosmic microwave background. Boom baby!
To my knowledge, this is because the Universe wasn't formed with
all the matter (or whatever you should call whatever existed right
after the big bang) in a completely regular pattern (or if it was
the case that anti-matter had this big fight with ordinary matter
after the Big Bang, it's really not that important I guess), and I
guess this is the reason why we have a highly diverse universe
today, inhabited by galaxies, black holes, and Justin Bieber.
Question
What would the Universe look like if there were no irregularities in it from the get-go? Would we have a big massive black hole in the middle (if one even can talk about a middle), would the Big Bang never happen, or have I just misunderstood the whole thing, making my question completely nonsensical?

Bonita Cole Inc. acquired the following assets in January of 2015. Equipment, estimated service life, 5 years; salvage value, $16,000 $559,000 Building, estimated service life, 30 years; no salvage value $675,000 The equipment has been depreciated using the sum-of-the-years’-digits method for the first 3 years for financial reporting purposes. In 2018, the company decided to change the method of computing depreciation to the straight-line method for the equipment, but no change was made in the estimated service life or salvage value. It was also decided to change the total estimated service life of the building from 30 years to 40 years, with no change in the estimated salvage value. The building is depreciated on the straight-line method. (a) Prepare the general journal entry to record depreciation expense for the equipment in 2018.

Create a program named "Your last name_Vacation" This program will prompt Frank to choose a number between 1 and 6. Use a switch…case to determine which number he chose. Use a Do…while loop to return to the prompt if the number is <1 and >6. 1 - Hawaii – 7 days / 6 nights 2 - New York – 3 days / 2 nights 3 - London – 7 days / 6 nights 4 - Bahamas – 7 days / 6 nights 5 - Miami – 3 days / 2 nights 6 - Los Angeles – 3 days / 2 nights The default will be; Stay Home – 7 days / 6 nights Use a Do…while loop to return to the prompt if the number is <1 and >6. Create a message that tells Frank about his vacation he chose. Use a for loop to create a list when Frank enters his first name, last name, and age, then enters the same for his wife, son, and daughter. Ex. Frank Last Age Wife “ “ Son “ “ Daughter “ “ Frank will input the departure date of his vacation. The final output should be in the following format; Congratulations!

Even organizations as large and successful as State Farm Insurance have to plan for the future. Without planning, strategies can become obsolete as the environment changes, and organizations can miss opportunities for growth. In short, an organization without adequate planning has no sense of direction or purpose and risks becoming mired in the present or the past. For State Farm, planning involved helping customers plan for their future.
State Farm has been a leader in the highly competitive insurance industry for more than 80 years. The company, proclaimed in its ads as being “like a good neighbor,” has been at the forefront of insuring customer liabilities. With 16,000 exclusive insurance agents across the United States, State Farm management believed it had a perfect opportunity to add more financial services. The deregulation of the banking industry in 1999 and the explosion of the Internet paved the way to achieving this goal. Today, State Farm Bank offers traditional services like loans and deposit accounts, but without actual bank buildings and at lower fees. Clients can do every typical banking transaction either on-line, over the telephone via State Farm’s 24/7 call center, through ATM machines, or through the same agents that sell the company’s insurance products.
State Farm’s move into banking was no simple matter. To protect consumers, it has had to meet requirements keeping the line between insurance and banking very clear. The State Farm insurance company provides insurance products and services and is required by law to be separate from the State Farm banking company that offers loans and deposit instruments. The State Farm mutual fund organization is yet another separate entity providing mutual funds through agents. Since State Farm mixes multiple businesses, it doesn’t have the same flexibility as traditional banks. For example, State Farm Bank doesn’t provide loans directly through automobile dealerships. It is subject to federal banking laws rather than state laws because it is technically a thrift institution, a category that includes savings banks and savings and loan organizations.
Diversifying into different businesses is creating new opportunities for State Farm, and banking services is natural fit. Agents find that their insurance review is the perfect opportunity to bring up the topic of financial services and to make customers aware of their company’s available services. Now when clients buy a new car or change insurance coverage, an agent can offer to help them with the loan; it’s a natural to talk about auto insurance and auto financing. Perhaps the best example of the flexibility State Farm can offer customers is found in the aftermath of Hurricane Katrina. Customers with mortgages through State Farm Bank received two 90-day extensions on loan payments. State Farm also forgave the interest on credit cards and allowed customers to miss payments for a period of time.
For now, State Farm Bank is focused on growing the business among current customers and adding new ones as clients refer friends and relatives. A unique bank with tremendous resources, State Farm Bank sees excellent opportunities to expand business beyond retail customers.
In summary: State Farm Bank resulted from the insurance company’s plan to diversify into the financial services sector. With more than 16,000 agents selling insurance products nationwide, moving into banking services was a natural fit, though not a simple transition. Now when State Farm agents talk to customers about homeowner or auto insurance they can also discuss financing options. State Farm Bank presents tremendous growth opportunities for State Farm.
