The Chemistry
Years ago, an important precursor to acrylic acid (CH2=CHC=OOH), a key organic
building block for many useful products, was ketene (CH2=C=O). One way to
make ketene was the vapor-phase pyrolysis of acetone (CH3C=OCH3). Pyrolysis
means heating in the absence of oxygen. The overall endothermic reaction is:
CH3COCH3 CH2CO + CH4
Jeffreys (1964) claimed the rate is 1st order in acetone vapor. The following
elementary gas phase mechanism can explain this dependence and the products:
CH3COCH3 ⇔ CH3C.
O + .
CH3
CH3C.
O CH2CO + .
H .
H + .
CH3 + M CH4 + M
The symbol M represents a third body – any species in the reacting vapor. The
“dot” species like .
H are free radicals. A pseudo steady-state hypothesis (PSSH)
analysis (not shown here) of this 3-step mechanism consistent with the observed
rate data reveals that the slow step is the forward direction of the first step. This
suggests collapsing the first two steps into an effective single step:
CH3COCH3 CH2CO + .
CH3 + .
H
The presence of .
H and .
CH3 radicals can give rise to carbon deposition (coke)
through a complex set of rapid reactions not shown here. To acknowledge the
potential of this undesirable byproduct formation, three other elementary reactions
are added below. The C2H6 potentially can react further to form coke.

CH3 + M C2H6 + M .

Task: I choose cellphones addiction
Sources:
The Power of Habit by Charles Duhigg / Chapter 9 only
The Addictive Personality by Craig Nakken / Part 1 &2 &3 only
At least 2 additional outside sources : I will add two articles about cell phone addiction as PDF
Organization:
Introduction:
• Interesting hook
• Background information on habits/addictions in general and that leads to the addiction you are researching in particular. You may want to include the numbers of people who suffer from this addiction. (Because you are using so many sources, you will NOT list them in the introduction.)
• A thesis statement about the addiction you are researching. Write this AFTER your body paragraphs because the thesis is the main idea of your research.
Body Paragraphs – AT LEAST 3
• Your body paragraphs will follow the structure we have learned in class. You will have a topic sentence and 3 sets of statement of support, quote in context, and explanation.
• The topics of the body paragraphs are your choice based on what you find in your research.
• Some topics may be:
a general paragraph about addiction.
a paragraph about the addiction you are researching
treatments for the addiction you are researching
culpability for the addiction (what organizations, or industries benefit from the addiction?)
the future of the addiction
any other paragraph you could write about the addiction
Conclusion:
• Restate your thesis.
• Summarize your subpoints in 1-2 sentences.
• End the essay in a logical way. This may be a general statement about recovery from a gambling addiction, a call to action, a tie back to your hook, or any other ending that is logical.
Works Cited
• List every source used in MLA format and attach as a separate page to the essay
Important Notes:
You may use additional quotes or paraphrases in the body paragraphs as long as they are properly introduced and explained.
Don’t forget that plagiarism is cause for failure. This must be your paper written in your words. Every time you copy more than three consecutive words from a source, you must cite it. I take this very seriously and so should you. Your essay must be submitted through Safe Assign in Blackboard. Safe Assign does not “catch” everything, but I can generally tell when the words you are using are not your own.

Film Humanities Assignment Help
answer the 2 questions below in 250 words each (500 words total)
This is a Film major class, so use some terminology of film studies
Question 1: Please read this film still. (File 1)
Pay attention to how the image is composed. Where is the camera positioned? How are the various elements of the shot arranged and framed (mise-en-scène). Take note of the objects that are closest and furthest away from the camera to understand what’s highlighted in the scene. How is the scene lit? What atmosphere is being created? How are the actors dressed, grouped, and positioned? What themes and meanings of the film The Murderers Are Among Us are conveyed in this film still? (250 words)
Example: This film still from Wolfgang Staudte’s The Murderers Are Among Us captures Susanne Wallner and Hans Mertens staring out the broken glass windows from their apartment and into the ruins left behind by the war. The broken glass in this scene can symbolize the fact that the horrors of the war cannot be hidden and are always present even in what would be assumed to be the comfort of your own home. The war has changed the entire country and their everyday lives, evidenced by the fact that Susanne must now live with a complete stranger like Hans Mertens. The apartment itself is very dark with many shadows symbolizing the sadness and uncertainty that both Susanne and Hans must carry on for the rest of their lives as the entire country tries to recover from the destruction and violence of the war. Susanne’s face is brightly lit while Hans’ face is hidden behind the shattered glass and shadows of the apartment. They look onto the present of Germany and possibly onto the distant future of the country. Susanne looks on with determination to overcome the obstacles that such a situation has presented while Hans looks on in bitterness and disappointment for the actions seen during the war. Susanne is also dressed in bright clothes while Hans is shown wearing dark clothing representing Susanne’s optimism towards the future of Germany and her commitment to helping Hans overcome his guilty conscience towards the horrors of the war. Wolfgang Staudte also makes reference to past German expressionist films throughout this film and he does it here too with his play with light and shadows reminiscent of films such as The Cabinet of Dr. Caligari.
Question 2 : Analyze the first sequence (end at 2:13 in the film)
How many individual shots does the sequence consist of? What can be seen? What filmic techniques are prominently used in this sequence (from camera angles and movements to lighting and to editing)? What is the symbolic meaning of the sequence’s visual elements? What can be said about the music? What picture of Germany after the war is being conveyed in this sequence? What clues does this opening sequence provide for the ensuing film narrative?

LOOK AT THE PROPASL
Interactive Online Communication and its Impact on Public Relation
The content area of the project is interactive online communication and its impact on public relation. Interactive communication refers to the exchange of ideas between different parties. In this communication, all parties engage actively and can affect one another. It is dynamic, which means it is two way. In the current times, the presence of the internet makes interactive communication better.
The reason for conducting this kind of project is to make awareness and let people know how much important interactive online communication is and how it impacts public relations. As the internet is becoming more and more expendable, the significance of interactive online communication is proving to be more evident. The communication here can happen in different ways which include texts, emails, or using different social media sites. The motivation behind this project is also to get to know how this communication is conducted. The features of online communication include the digital format in which it is undertaken. Any interactive online communication uses digital platforms which use the internet.
The objectives which are part of the motivation behind this kind of study is to understand the delivery of this information. Online communication has a delivery format which is immediate. Any information reaches the other end of the communication almost instantly. This is made possible by the fact that the information travels very fast by use of an electronic form of transmission. Another objective is to understand how interactive communication is. Since the delivery of the messages and information is immediate, there is a high level of interactivity between both sides of the communication. Understanding the individuality is also a big motivation for this study. What’s the process of this communication? Is the question to answer in this case. The way interactive online communication is exchanged between parties can be customized, considering the needs of each party (Besley, Dudo & Yuan, 2018).
Communication study is all about how people communicate with each other. Communication studies help people understand that communication is interactive or rather social. Communication studies encompass different fields which include interactive online communication and its impacts. It also explains the problems of different kinds of communication (Bernstein, 2019). All these factors are what makes this project a communication study.
The impacts of interactive online communication on public relations is the question I hope to answer by the end of this project. Public relations refer to the communication process that individual people or organizations implement to mutually benefit from the public (Supa, 2019). Public relations specialists must have communication plans and mostly use media or other platforms to create a positive name and image and maintain their good relationship with the audience targeted. The public relations specialists will mostly use online media as it is faster, and it reaches out to a larger mass than direct communication. Conducting this study will help understand how these specialists interact with people on the media and its impacts.
To answer the question of the impacts of interactive online communication on public relations, it will require strategies or effective methods to come to the solution. One of the best strategies is the online research. There are several articles by different authors who have already done research explaining how online communication affects public relations. Using different articles or online sources will help to come up with a lot of information. Summarizing this information will help to conclude on the most crucial impacts. For variability, first-hand information is also important. To obtain this, surveys come in handy. Getting information directly from some of the public relation specialists will help a lot.

Response One Attached, I will post response to later when I receive it.
Please make sure to include the chart, I have attached an example of a chart.
https://www.mindtools.com/pages/article/newLDR_86.htm
First, review your work from the small group discussion in Module Four, including your group’s final SIPOC diagram, and consider the relationships between and among the individuals involved—the suppliers and the customers. Also, be sure to read Forming, Storming, Norming, and Performing: Understanding the Stages of Team Formation, which describes Tuckman’s theory of the stages of group development, formation, work, and cessation.
Next, evaluate your selected final project case study in order to deconstruct it into each of Tuckman’s stages, which will enable you to make the Improve recommendations for your case study’s organization. Create your own Tuckman’s model using the PowerPoint SmartArt graphics tool and post it to the small group discussion.
Address the following in your initial post:
- How does Tuckman’s theory of the five stages of group development help you to understand your selected case study?
- How can you apply each piece of the group development process to your case study?
- How can an effective team building process help to prevent issues from occurring with a dysfunctional team?
- What do you see as being your greatest challenge to applying Tuckman’s theory of group development to your selected case study as well as to your organization’s specific conflict?
Be sure to reference the Module Four small group discussion in order to review your thinking about SIPOC, particularly about the suppliers and customers.
In your response posts, be sure to reply to each of your classmates in your group. Work with your group members to identify and analyze each of the five stages of group development as they pertain to your final project case study. Produce a final Tuckman’s model for your group.
