The most common experimental technique to perform elemental analysis is combustion analysis, where a sample is burned in a large excess of oxygen and the combustion products are trapped in a variety of ways. A 99.99% pure, 0.4831 g sample containing only carbon, hydrogen, and nitrogen is subjected to combustion analysis, resulting in the formation of 1.353 g CO2, 0.2750 g H2O, and 0.1833 g NO. What is the empirical formula of the sample?

Perform an experimental analysis to test and compares the relative running times of the methods shown in the following Code Fragments. Calculate the execution time of each example in milliseconds and draw the results in one chart using line chart type. [HINT: use the following five different inputs size to check each example (1000, 10000, 100000, 1000000, 10000000). You can generate each array using random number generator to fill the array with the pervious input size]. /** Returns the sum...

The use of ratio analysis is a common technique in financial management for interpreting values on financial statements and putting them into some context about how an organization is performing. The same approach is extremely valuable in operations management for understanding how efficiently an organization is producing services for patients. A health care provider organization operates as a production function with inputs and outputs, just as a factory does that produces goods for sale. In the case of a health...

In finance, discounted cash flow (DCF) analysis is a common technique of placing value on a project or company. All of the future cash flows are projected and discounted by using cost of capital to determine their present values (PVs). Adding up all future cash flows, both incoming and outgoing, provides the net present value (NPV). Respond to the following in a minimum of 175 words: Give an example of a situation where a building contractor may want to use...

A compound containing only C, H and O was subjected to combustion analysis. A sample of 9.550×10-2 g produced 1.825×10-1 g of CO2 and 1.120×10-1 g of H2O. Determine the empirical formula of the compound and enter the appropriate subscript after each element. If the molar mass of the compound is 184.276 g/mol, determine the molecular formula of the compound and enter the appropriate subscript after each element.
