Ethanol, is obtained from renewable crops such as corn, which use the sun as their source of energy. In the United States, automobiles can now use a fuel known as E10 that contains 10.0% ethanol and 90.0% unleaded gasoline by volume (%v/v). Ethanol has a melting point of -115 , a boiling point of 78 , a heat of fusion of 23.6 , and a heat of vaporization of 201 . Liquid ethanol has a density of 0.796 and a specific heat of 0.588 .1. How many kilojoules are needed to vaporize 5.00 of ethanol at 78 °C?2.When 25.0 of ethanol at -20 is heated to , how much energy, in calories, is required?3.If a 25-gallon gas tank is filled with E10, how many liters of ethanol are in the gas tank?4.Write the balanced chemical equation for the reaction of ethanol with oxygen gas to produce carbon dioxide and water vapor.5.How many kilograms of carbon dioxide, , are produced from the complete reaction of the ethanol in a full 25-gallon gas tank?6.When 25.0 of ethanol at -20 is heated to , how much energy, in calories, is required?

  1. Ethan’s class is handing out balloon arrangements consisting of 4 balloons each. Each balloon has an equally likely chance of being red, blue, or yellow. Ethan created a spinner to simulate this probability. Here is Ethan’s data from 30 trials of 4 spins on the spinner (r = red, b = blue, y = yellow):

    ybrr bybb rbbb rrry rbbb rryy yybb ryry ryyr rbyr ryyr rryy rrrr yrby bbyy byyr byyr byyb rbby ybry rryy rbrr rybb bbbr rrbr ybry ryrr rryb rrrb rryr

    According to this data, what is the experimental probability that an arrangement will contain exactly one blue balloon?

    A 0.25

    B 0.633

    C 0.667

    D 0.367

This assignment builds on the Risk Management Program Analysis Part One assignment you completed in Topic 1 of this course.

Assume that the example risk management program you analyzed in Topic 1 was developed by and is now currently implemented by your health care employer/organization. Further assume that your supervisor has asked you to present a high-level summary brief of this new risk management program to a group of administrative personnel from a newly created community health organization in your state who has enlisted your organization’s assistance in developing their own risk management policies and procedures.

Compose a 1,250-1,500 word summary brief that expands upon the elements you addressed in the Risk Management Program Analysis Part One assignment. In addition, analyze the following:

  1. Explain the Joint Commission’s role in the evaluation of an organization’s quality management processes.
  2. Describe the roles that different levels of administrative personnel play in establishing or sustaining operational policies that are focused on employer-employee organizational risk management policies.
  3. Explain the relationship of risk management programs and compliance with ethical standards.

In addition to your textbook, you are required to support your analysis with a minimum of three peer-reviewed references.

Prepare this assignment according to the guidelines found in the APA Style Guide, located in the Student Success Center. An abstract is not required.

This assignment uses a rubric. Please review the rubric prior to beginning the assignment to become familiar with the expectations for successful completion.

You are required to submit this assignment to LopesWrite. Please refer to the directions in the Student Success Center.
