Lab Topic:

 

I need :

1- Lab report (include Excel graph of the data which I already have on Excel)

2- two lab questions need to be answered plz.

-please see the attachments…

@Due Monday evening time plz…

determine the internal pressure of medication bottle at the bottle cap  when inverted and  which is filled with water  and other filled with viscous medication fluid.

answer should be technically written with purpose, calculation, explaining both liquid produce different pressure

1. You are working in the lab and you find a bottle with mysterious liquid in it that has a label with the following information: vapor pressure of 405 torr at 57.8 C and 642 torr at 71.0  C . What is the normal boiling point of this liquid? Using the table below of common boiling points, what is the mysterious liquid? (20 points)

Table 1. Boiling points of compounds by their common name.

     

Compound  Boiling Point (C)

Revan                  54.2

Odion                   64.7

Scabrous              76.7

Malgus                  80.1

2. Use the following data to sketch a cooling curve and calculate the amount of heat lost for 1.5 moles of trihexalon, a biological weapon of mass destruction that needs to be cooled for transport. Start the curve 110 C and at +16C ,

Table 2. Thermochemical properties of trihexalon

Boiling Point  93C

Melting Point  21C

Heat of Vaporization ( HVap) 23.7kJ/mol

Heat of Fusion ( Hfus) 11.7kJ/mol

Molar Heat Capacity 123.1 J/mol   C

Molar Heat Capacity (g) 63.4 J/mol   C

Molar Heat Capacity (s) 27.8 J/mol C

 

For this assignment, make sure you post your initial response to the Discussion Area by the due date assigned.

To support your work, use your course and text readings and also use outside sources. As in all assignments, cite your sources in your work and provide references for the citations in APA format.

Start reviewing and responding to the postings of your classmates as early in the week as possible. Respond to at least two of your classmates. Participate in the discussion by asking a question, providing a statement of clarification, providing a point of view with a rationale, challenging an aspect of the discussion, or indicating a relationship between two or more lines of reasoning in the discussion. Complete your participation for this assignment by the end of the week.

Discussion Question 1

Using the South University Online Library or the Internet, research acids, bases, and salts that are used in therapeutic processes. On the basis of your research, respond to the following:

• Define an acid, base, and salt as they apply to chemistry.
• State three examples each of acids, bases, and salts commonly used in therapeutic processes.
• From the examples you state, select one acid, one base, and one salt and describe specifically how and where they are used in therapeutic processes.

Discussion Question 2

Using the South University Online Library or the Internet, research buffered aspirin. On the basis of your research, respond to the following:

• Define a buffer and explain how a buffer works. [Note: be sure to address the role of conjugate salts.]
• Analyze and explain the buffer system in buffered aspirin (carboxylic acid).

Miami Florida is considered ground zero for climate change (), in particular rising seas will not only drown coastal sections of the city but will disrupt our local supply of drinking water.

Based on what you have learned so far from this class, discuss the following: 

• Explain where the drinking water from South Florida primarily comes from and why would rising sea levels disrupt this supply?
• What efforts can be made and are being made to mitigate the effects of rising seas on our drinking water?
• If you were a local politician, what advice would you give to state and federal officials on the best way to ensure residents in South Florida had a steady supply of drinking water for many years to come?

For this assignment, you will be looking at the science behind a recipe not just the culinary perspective. Select a recipe of your choice. It should be ‘moderately complicated’ that is to say it should have five or more ingredients and a number of preparation steps.

• Describe the ingredients that are key to the recipe or that may be unusual and explain what their purpose is in the dish. The intended purpose of the preparation steps of the cooking should also be described. The choice of heat source/method should  also be explained in terms of any reactions it might bring about.
• As a last step, propose some variations (choice of protein, method of heating, etc.) that might work.
• This is probably a first for all of you so I have provided an that should help you understand the assignment.

In an APA-formatted document 2-3 pages, not including cover page and reference page, provide an account of your experiences to date with individuals who are taking psychoactive medications.

  

Part A: You are the Environmental Coordinator for a demolition company that still prefers the use of dynamite sticks for demolition. You are tasked with the compliant and safe transport of dynamite to the demolition sites. Identify the proper placarding, labeling, and shipping documentation of the transport vehicle as required by the DOT. 

Part B: The vehicle that was transporting the dynamite sticks in Part A has been struck by another vehicle. A small fire appears to be spreading from a tire on a vehicle at the scene of the accident. Identify the explosive material that could be involved, and describe the chemical interaction that could be occurring as a result of the collision between the two vehicles. What immediate action should the EHS and FS responders take to protect human health and the environment? 

please see the attachment for the lab manual.

also, the collected data from the lab experiments. 

I need your help with typing the lab report and organize the collected data in tables  (Make a table for each part of the lab  plz) 

@ due this Monday Feb-10 

please lmk if you have any questions..
