What would be the effect of each of the following sources of error in the reaction between Mg and HCl? Would they result in a high, low, or unaffected value for the heat of reaction? Why?

A. The calorimeter absorbs heat.
B. The thermometer reads 2 °C low at all temperatures.
C. The actual molarity of the HCl is slightly higher than reported on the bottle.

D. The mass of the filter paper was not subtracted in the determination of ∆H1.

The following data were taken from the financial statements of Hunter Inc. for December 31 of two recent years:

The income before income tax was $447,700 and $391,700 for the current and previous years, respectively.

a. Determine the ratio of liabilities to stockholders' equity at the end of each year. Round to one decimal place.

b. Determine the times interest earned ratio for both years. Round to one decimal place.

Explain what evolutionary adaptations, in general, exist in hyperthermophilic bacteria in terms of their cell membranes and cellular proteins. Your answer should explain how such adaptations provide advantages in terms of protein and membrane function at extremely high temperatures.

Write a static generic method PairUtil.minmax that computes the minimum and maximum elements of an array of type T and returns a pair containing the minimum and maximum value. Require that the array elements implement the Measurable interface of Chapter 10.

What is the osmotic pressure, in torr, of a 3.00% solution of NaCl in water when the temperature of the solution is 45 ºC? Enter your answer scientific notation.

reate a class Song with the data members listed below:

• title: string the name of the song. (initialize to empty string)
• artist: string the name of the artist. (initialize to the empty string)
• downloads: int the number of times the song has been downloaded. (initialize to 0)

Include the following member functions:

• default constructor,
• a constructor with parameters for each data member (in the order given above),
• getters and setter methods for each data member named in camel-case.  For example, if a class had a data member named myData, the class would require methods named in camel-case: getMyData and setMyData.
• double grossRevenue(double price): This function should take in a price per download and returns the total revenue for the song (revenue = price * downloads).

You only need to write the class definition and any code that is required for that class (i.e., header and implementation).

NOTE: you must not use the implicit "private" for class data types and methods. Include public or private explicitly.

What is profit? There is accounting profit discussed in the textbook: profit = total revenues – explicit costs Let me relate profit to the factors of production. The three factors of production according to the textbook are land, labor, and capital. Let me add a fourth factor found in many economics textbooks: a return to the entrepreneur! (Entrepreneurs provide two services to society: organize resources and assume risk.) So how does a firm or entrepreneur maximize its profits? The answer is simple: provide society what it wants. (Note: this may be different from what society needs.) Note: Given this perspective, profit is something inherently good, something to be maximized, not feared. Let’s refine our understanding of this concept. Normal profit is that return necessary to attract and maintain entrepreneurial participation in some economic activity. Economic rent is return greater than normal profit.

The wavelength of the four Balmer series lines for hydrogen are found to be 410.1, 434.3, 486.6, and 655.9 nm. What average percentage difference is found between these wavelength numbers and those predicted?

In C++, create two vectors, one a vector of ints and one a vector of strings. The user will fill each one with data, and then your program will display the values.

1. Copy the template file /home/cs165new/check10a.cpp to your working directory.
2. For this assignment, in order to focus our practice on the syntax of the vectors, you can put all of your code in main.
3. Create and display a vector of ints as follows:
   1. Create a vector of ints.
   2. Prompt the user for ints until they enter 0, and store them in your vector.
   3. Loop through all the numbers in the vector and display each one.
   4. When you loop through, make sure to use the size of your vector in your condition (not a separate integer from above).
4. Create and display a vector of strings as follows:
   1. Create a vector of strings.
   2. Prompt the user for strings until they enter "quit", and store them in your vector.
   3. Loop through all the strings in the vector and display each one.
   4. When you loop through, make sure to use the size of your vector in your condition (not a separate integer from above).
5. You do not have to use iterators for this assignment (but you are welcome to if you would like). It can be done using the [] operator.

A speeding car is traveling along a straight road with a constant speed of 100 km/hour. It passes a police car. The officer starts 5.00 s after the speeder passes. The police car accelerates uniformly (i.e., at a constant acceleration) for 10.0 s, at the end of which its speed is 120 km/hour. After that, the police car moves with the constant speed of 120 km/hour till it reaches the speeding car.

How far ahead of the police car is the speeding car when the police car stops accelerating? How long after it stops accelerating does the police car reach the speeding car?
