Hello, I am struggling with the chemistry discussion question and would like an answer for it.
Thank you.
Objectives:
Demonstrate how to convert the number of atoms into mass or moles.
Explain how the mole ratio is derived from the chemical equation and its fundamental importance in solving for amounts in chemical reactions.
Demonstrate the use of the mole ratio in problem solving through dimensional analysis.
This discussion board is designed to accompany the materials in Chapter 4 which discusses molarity and solute concentrations.
Background:
Professionals in a scientific laboratory and in the healthcare field need to accurately prepare solutions for a number of reasons. If you wear contacts, you probably use a saline solution to rinse your contacts.
What solutions do you use at work? How would you calculate the amount of solute to the solvent to make the solution?
If you do not wear contacts but you use or make cleaning solutions for your housework, how would you accurately prepare solutions to clean?
What solutions do you use that use percent concentration?
Assignment:
Use the materials in your textbook or from online sources to learn/review molarity. Remember to cite your sources.
Respond to at least two other students.
Contribute to an ongoing discussion by responding to comments made to your posting or to comments made by other students to other postings.

Hello. I am respectfully requesting assistance with the following question:
The sum of the measures of the angles in any triangle is 180°. Justine has a triangular area in her back yard where she intends to create a garden. If the largest angle is five times the smallest and the middle angle is 20° more than twice the smallest, find the measure of each angle.

Hello, I am stuck designing a finite state machine that detects a specific 8-bit sequence (10100001) and when this sequence is detected the output of the circuit is 1 otherwise it is 0. The circuit has 2 inputs a logic 0 and a logic 1 input that enters the corresponding digit into the circuit. The tricky part is that after 16 bits are entered that don’t match the needed sequence (10100001) the system shuts off until the reset button is pressed. I also can’t use registers.Here are some more guidelines:There is no actual clock- the release of the push button (the 1 and 0 button) produces the transition that is used to trigger the flip flops (much like a clock would).Hint: You might put the outputs of the two push buttons into asynchronous inputs of a flip flops. The output of this flip flop is then used as the actual “input” value.I have started working on this problem, but where i run into trouble is the reset section as well as the asynchronous clock function. I need the circuit for this problem so then I can see what I did wrong and learn from there. An answer with some explanation would be helpful! The Due Date is final, I need time to study for the final and I can’t stay up late waiting for explanation. The price however, is negotiable to fit within the deadline. If you need any other information please let me know, I will be working on this all day anyways so I will be available.

Hello,
I am stuck on these reactions:
#1 Which mechanism is correct for AlCl3? I have seen both mechanisms used, but I am not sure why one is favored over the other for certain reactions.
#2 & 3: I am not sure which resonance for each reaction is the correct one. Can someone explain which resonance is the correct one to use when reacting the diene with the dienophile and why?
Thank you!

Hello, I am trying to compute an answer to a question to get a better understanding and am having difficulty. What formula should be used? The question is asking for the amount of time (months and years)it would take to pay off a $180,000 loan at an APR of 10% if the person could pay $3,500 per month and then $4,000 per month.

Hello. I am trying to determine whether or not to approve or deny the following study.
Your university includes a college of veterinary medicine. In the past, the students practiced surgical techniques on dogs acquired from a local animal shelter. There have been some objections to this practice and the veterinary school wants the approval of your committee to continue this practice. They make the following points:
1. Almost all of the animals will eventually be killed at the animal shelter. It is wasteful of life to breed animals for the vet school when there is an ample supply of animals that will be euthanized anyway.
2. It costs at least 10 times as much to breed animals for research purposes.
3. Research with dogs from animal shelters and the practice surgeries will, in the long run, aid the lives of animals by training veterinarians.
A local group of animal welfare activists demanded that you deny the school’s request. They argue that the majority of these animals are lost or stolen pets and it is tragic to think that previously loved dogs could end up on a surgical table for an experiment. Furthermore, they claim that as people become aware that animals taken to shelters may end up in research laboratories, they will stop using the shelters and simply set these animals free.
I’m really not sure which to do. I see both sides.
