Your task is to prepare a presentation using a tool such as PowerPoint, Prezi, or Google Slides to explain how the MRE flameless ration heater works. The group you will be presenting to wants to know how and why the heater can be used to heat up food, what the different chemicals that are present do, and how chemical principles such as bond energy and collision theory affect the operation of the heater. This should include at least 5 slides with a visual on each slide.

 Include the following: 

1) Include an overall description of the MRE and the flameless heater including its contents and use.

2) Describe the relationship between the bond energy of the reactants and the products and what type of reaction this is (endothermic or exothermic).  Include the concepts of activation energy and include a graph to illustrate the correct type of reaction.

3) Include the concept of collision theory. What does collision theory say about the rate of a reaction? Discuss the collisions that must occur for the MRE flameless heater to work.

4) If you wanted to increase the reaction in the flameless heater, what could be changed based on your knowledge of collision theory?

 5) What part does each substance play in the flameless heater? Include any information about the substance that will help explain why the reaction occurs as it does. Be sure to include the concepts of surface area and the function of a catalyst in this description.

Completing this is five paragraphs is acceptable as well

Variance and standard deviation. Calculate the variance and the standard deviation of U.S. Treasury bills, long-term government bonds, and small-company stocks for 1950 to 1959, 1960 to 1969, 1970 to 1979, and 1980 to 1989 from Table 8.1. Which had the highest variance? Which had the lowest variance? Click on the Spreadsheet Learning Aid to see Table 8.1-Year-by-Year Returns, 1950-1999. Hint: Make sure to round all intermediate calculations to at least seven (7) decimal places. The input instructions, phrases in parenthesis after each answer box, only apply for the answers you will type.
