1)Calculate the partial pressure (in atm) of H₂ at equilibrium when 3.49 atm of CO and 5.63 atm of H₂O react at 1000 K according to the following chemical equation:

Report your answer to three significant figures in scientific notation.

2A mixture containing CH₃OH, HF, CH₃F, and H₂O, all at an initial partial pressure of 3.22 atm, is allowed to achieve equilibrium according to the equation below. At equilibrium, the partial pressure of H₂O is observed to have increased by 0.83 atm. Determine K_p for this chemical equilibrium. Report your answer to 3 significant figures in scientific notation.



CH₃OH(g) + HF(g) ⇌ CH₃F(g) + H₂O(g)

1-Calculate the partial pressure (in atm) of CH₃OH at equilibrium when 4.84 atm of CH₃I and 4.84 atm of H₂O react at 3000 K according to the following chemical equation:

Report your answer to three significant figures in scientific notation.

2-Calculate the partial pressure (in atm) of H₂O at equilibrium when 59.6 g of CdO and 3.21 atm of H₂ react at 800 K according to the following chemical equation:

Report your answer to three significant figures in scientific notation.

Present at least two paragraphs describing your thoughts about the course. This assignment is worth double points (10 points). Here are some points to help guide your reflections:

1 . Your thoughts about the format of the course.

2. Your thoughts about the content.

3. Your thoughts about the assessments.

4. Anything else you would like to add?

On this painting Hubert Robert, Le Salle des Saisons du Louvre, c. 1800. Musée du Louvre, Paris. Examine the two people standing in the front carefully. How do people engage with the artwork on show in the gallery? What would you say about their nonverbal cues?

Calculate the equilibrium PCO2 at 25°C for reaction below. Report your

 answer to three significant figures. CaCO3(s) ⇌ CaO(s) + CO2(g)

The simplest known photosynthetic system is bacteriorhodopsin (BR) , a 26KD membrane protein found in halophilic bacteria. BR is a simple light-activated proton pump which translocates one H+ per photon absorbed. The protons are then used to synthesize ATP with a typical ATP synthase enzyme. The peak absorption of BR is in the green light range (565 nm photons).

a. If 3 H+/ATP is required for synthesis what is the % efficiency of this photosynthetic system? Assume the DG’ for ATP hydrolysis in -12 kcal/mol (-50. kJ/mol) under the real cellular conditions at 37^oC.

b. Look up a value for the efficiency of a typical green plant (PSI and PSII) photosynthetic system. What is it (there are any different estimates out there—pick one)? How does it compare? What are some of the disadvantages of the simple BR system as compared to the extremely complex green plant system?

time of development of Photosynthesis?

How did development of Photosynthesis changed environmental conditions on planet Earth?

Briefly discuss the interaction between Administrative Procedure and Environmental Regulation and how it affects the development of Environmental Law.

I need a proper discussion post on:

Biotic Interactions and Population Dynamics: How does energy move in food systems

Directions: record any of the following events that you observe in your daily routine:

• Any elements, compounds, mixtures or solutions
• Any physical or chemical changes in the elements, compounds, mixtures, or solutions
• Any chemical reactions
• Any event that illustrates any of the gas laws
• In your notes describe the event and relate it to the concepts from the course. You should write in your own words, describing the events as they happen

I've Got three Demonstrations but I need to Modify variables (read the caption and details below ).

1) http://demonstrations.wolfram.com/DivingBell/

2) http://demonstrations.wolfram.com/PascalsBarrel/

3) http://demonstrations.wolfram.com/TheHydraulicPress/

1. Did you know who is the Best of battery?

Write a lab report that includes the title, purpose, and conclusion

The final activity is to view some Chemistry demonstrations and document the activity and its results. This will be your lab report.

Directions: Follow the steps below to complete the assignment.

Step 1. Go to the link below to view demonstration videos.

Step 2. Choose three videos from the web site. You should view each videos several times.

Step 3. After a preliminary view of the videos, look at the document below. This document includes the information that you should document when you either view demonstrations or conduct experiments. It also includes the rubric so you will understand how to earn points.

Step 4. Now that you have chosen your video demonstrations, take one demonstration at a time. View the video again, taking notes carefully. After you are certain that you understand the concepts of the demonstration you are ready to write your report. Use the guide below to write your reports.

A. The title is the name of the demonstration video. The title should concisely describe the basic concept that is demonstrated in the lab activity.

B.Purpose - State the purpose of the lab beginning with the following words, To determine:

C.Hypothesis -State the hypotheses of the lab. (The hypotheses should be an 'if/then' statement.)

D. Equipment -List the equipment used in the lab. Procedure – List the procedure used in the lab. Data Table – List the data that is generated from the demonstration. You may want to create a data table. You may also create a bullet list.

Conclusion – Write 3 paragraphs that include the following information:

Paragraph 1:

a. Introduction: State the experiment

b. State the purpose of the lab

c. State the hypotheses.

d. State the outcome

Paragraph 2:

e. Discuss at least 2 sources of error that could happen: give a detailed explanation of each and how this may affect the collected data.

Paragraph 3:

f. Conclusion: provide a final summary of the demonstration.

I have eliminated answer D and really appreciate any help with this question.
