pre lab questions:

1. Define “acid” according to the Bronsted-Lowry theory of acids and bases.

2. Hypothesize what might occur to the sodium bicarbonate when it reacts in Part B of this experiment. What will you see?

3. The NaI might undergo one of two different reactions when it reacts with 18 M sulfuric acid in Part C of this experiment. Describe what happens in both of these possibilities (in words or with reaction equations)

4. Lookup the physical appearance of I₂ and Cl₂. What do they look like?

5. Hypothesize what might occur to the magnesium and copper metals when they react with HCl in Part D of this experiment.

1. What two characteristics of the data do you need to determine which binomial distribution to use?
2. What two characteristics of the data do you need to determine which Poisson distribution to use?
3. What two characteristics of the data do you need to determine which normal distribution to use?

(2) For the following scenarios determine if you should use Binomial, Poisson or Normal Distributions

(a) The experiment/problem involves 2 independent outcomes, a fixed number of trials with a known (fixed) probability of “success”

(b) The experiment/problem involves number of outcomes per area or time

(c) The experiment/problem involves determining the probability of certain measurements

Where is the image in a plane mirror formed?

Your friend Noelle suggests the following hypothesis: "The image of an object formed by a plane mirror is formed on the surface of the mirror." Design an experiment to test Noelle's hypothesis.

Available equipment: Plane mirror, object, masking tape, paper, meter stick.

Design and describe the experiment that you plan to perform. Remember that your prediction of the outcome if the expirement must allow from the hypothesis you are testing. Then perform the experiment and record the outcome. Explain the outcome using a ray diagram. Discuss whether the outcome agrees or disagrees with the prediction. If it disagrees, how would you convince Noelle that her idea has been disproven?

1. Does your result match what you had expected based on how you know enzyme activity is affected by temperature? Explain.
2. What changes would you make to improve this experiment? Provide at least one suggestion for improvement.
3. What could you do to increase enzyme activity in this experiment? Provide at least one suggestion.
4. Do animals have an enzyme that breaks down hydrogen peroxide? How could you test for the presence of such an enzyme?
5. What changes would you make to this experiment to determine the optimal temperature for this particular enzyme? Do a web-search to find the optional temperature for this enzyme. Include references to information sources.

1. Write a function named ”ThreeDicesAdd” to perform the following ”experiment” 1000 times: roll 3
six-sided dice and add their values. Put the outcomes in a list called addDiceList. So addDiceList should
have length 1000, and each of the 1000 elements should be an integer from 3 to 18. Plot the histogram of
the outcomes.
2. For the same experiment as in question 1, write a function named ”ThreeDicesAdd2” to increase the
experiment times (N) and see how the histogram of the outcomes changes. For each N, you will have one
histogram plot. Output all plots as a GIF file. (Choose N= 1000 : 10,000 : 1,000,000). matlab question

Frances Manufacturing makes a product with total unit manufacturing costs of $64, of which $36 is variable. No units were on hand at the beginning of 2015. During 2015 and 2016, the only product manufactured was sold for $96 per unit, and the cost structure did not change. Frances uses the first-in, first-out inventory method and has the following production and sales for 2015 and 2016:

1. Prepare gross profit computations for 2015 and 2016 using absorption costing.
2. Prepare gross profit computations for 2015 and 2016 using variable costing.

Proc. 2016-40 provides safe harbor rules for transactions involving acquisition of control in certain corporate transactions. Please identify one transaction under Rev. Proc. 2016-40 and discuss why you think IRS provided safe harbor for the transaction. Rev. Proc. 2016-40 and the related provisions are discussed in the article linked below.

Hardhat has a contract to construct a $5,000,000 bridge at an estimated cost of $4,000,000. The

contract is to start in 2016 and will be completed in 2018. Below is the data for 2016-18:

2016                          2017                         2018

Costs to date                                               1,000,000 2,900,000                 4,100,000

Est. costs to complete                              3,000,000                 1,200,000 -

Progress billings during year                   900,000                    2,400,000                 1,700,000

Cash collected during year                      750,000                    2,250,000                 2,000,000

Compute the percentage of completion, and record the journal entries to recognize revenue,

expenses, and gross profit for 2016-18 using the percentage of completion method (Do not

record journal entries for costs incurred, progress billings, and cash collected during 2016-18)?
