Methanol is produced by reacting carbon monoxide and hydrogen. A fresh feed stream containing CO and H2 joins a recycle stream and the combined stream is fed to a reactor. The reactor outlet stream flows at a rate of 350 mole/min and contains 10.6 wt% H2 , 64 wt% CO and 25.4 wt% CH3OH. This stream enters a cooler in which most of the methanol is condensed. The liquid methanol condensate is withdrawn as a product, and the gas stream leaving the condenser – which contains CO, H2 and 0.4 mole % uncondensed CH3OH vapor – is the recycle stream that combines with the fresh feed. Determine:

a) the molar flow rates of CO and H2 in the fresh feed

b) the production rate of liquid methanol (mol/min) and

c) the molar flow rate of the recycle stream.

(Draw and completely label the process flow diagram and determine all molar flow rate)

As a shareholder in Pinnacle, Mrs. Paul is excited about the $1,000 EPS (earning per share) she will soon receive in the form of dividends and she begins to plan her around the world cruise. However, as her broker, it is your job to figure out a way to explain why this is not likely to happen but that she might be able to cruise the Hawaiian Islands for a week.

Be sure to emphasis the difference between earning per share and dividends.

Linux Directories, File Properties, and the File System in C

Understanding Unix/Linux Programming

Your version of mv command

1. The mv command is more than just a wrapper around the rename system call. Write a version of mv that accepts two argument. The first argument must be the name of a file, and the second argument may be the name of a file or the name of a directory. If the destination is the name of a directory, then mv moves the file into that directory. Otherwise mv rename the file if possible.
2. Add comments to code.

Java Programming: spellcheck

Write code to read in a dictionary from the current directory called "dict.txt" (you can find this in the current directory/data)

Add each word to a hash map after splitting words and throwing away punctuation (see the demo).

open a file called "spell.txt" to check in the current directory.

Print out every word in spell.txt that is NOT in the dictionary.

Example:

if spell.txt contains:

hello, this is a test. 2152189u5
Misspelled! cApitalized

The output should be:
2152189u5
Misspelled
cApitalized

UNIX/TERMINAL ASSIGNMENT - DIFFICULT

Could you please type line by line what I should be entering in the terminal command line to complete the assignment as instructed?

INSTRUCTIONS AS FOLLOWS:

In this lab you will create a script to backup certain number of oldest or newest files in the current directory into a compressed archived file. The objective of this lab is to familiarize and gain proficiency with the following:

• Use of command line arguments

• Use of conditional statement

• Use of for loops

You need to write a script named backup.sh which will receive 3 command line arguments. The arguments are:

• The 1st argument is the string “old” or “new” indicating whether the oldest files or the newest files needs to be backed up

• The 2nd argument is an integer indicating how many files needs to be backed up.

• The 3rd argument is the name of archive file (tar file).

Your script should perform the following functions

• Check whether 3 arguments have been passed or not.

• If three arguments have not been passed display appropriate message and exit.

• Check whether the 1st argument is not the string “old” or “new” display appropriate message and exit.

• Create a temporary directory under current directory • Using a “for loop” copy all the required files in the temporary directory.

• Create an archive file of the copied files. The name of the archive files is the 3rd argument. Compress the archived file.

• Delete the temporary directory along with copied files.

Example execution: If user type the following ./backup.sh old 5 backup.tar The script will create a compressed archive file named backup.tar.gz in the current directory containing five oldest file in the current directory. ./backup.sh new 4 backup.tar The script will create a compressed archive file named backup.tar.gz in the current directory containing four newest t file in the current directory

How would I create a script named backup.sh and do the 3 arguments?

Have some Python and C++ experience, but Unix in Terminal is completely foreign to me so as much detail as possible would be appreciated.

Thanks!

A stock price is currently $30. During each two-month
period for the next four months it will increase by 8% or decrease by 10%. The
risk-free interest rate is 4%. Use a two-step tree to calculate the value of a derivative
that pays off [max(30-ST, 0)]2, where ST is the stock price in four months. If the
derivative is American-style, should it be exercised early?

On October 1, 2021, COVID Co. borrowed a $500,000 note at 12% interest and pledged $600,000 in accounts receivable as collateral. Additionally, COVID Co. was charged a finance fee equal to 1% of the borrowed amount. At the end of November, $400,000 of the assigned receivables were collected and remitted to the lender along with accrued interest.

Required:

Prepare journal entries to (A) record the borrowing, the assignment of receivables, (B) the collection on the receivables, and (C) the recognition of interest expense and remittance to the lender.

1. On January 1st, SGMI Co. issued a $795,000, 6.4% semiannual, 10-year bond to yield 7%. On October 31st, the company called 10% of the bonds for 102 plus accrued interest. Please create the journal entry and amortization table for this transaction.
