Suppose a particular mechanism has the following equilibria:

Ni(CO)_4(g) ⇌ Ni_(s) + 4 CO(g)               K₁ = 8.77             ΔH₁ = 190 kJ

MnO_(s) + CO(g) ⇌ Mn_(s) + CO_2(g)        K₂ = 490              ΔH₂ = 349 kJ

Mn_(s) + H₂O_(g) ⇌ MnO_(s) + H_2(g)         K₃ = 0.0149          ΔH₃ = -346 kJ

Determine the values of the equilibrium constant and enthalpy change for the net equation:

Ni(CO)_4(g) + 4 H₂O_(g) ⇌ Ni_(s) + 4 CO_2(g) + 4H_2(g)        K_c = ?     ΔH = ?

(You’ll want to review the rules for manipulating the stoichiometry of an equilibrium reaction and its equilibrium constant in section 14.3 of the textbook. It is different than using Hess’s Law to find the net enthalpy change.)

3 species do not appear in the net question. Which are they? Classify each as an intermediate or a catalyst. How do you know the difference?

During the first month of its current fiscal year, Green Co. incurred repair costs of $19,000 on a machine that had 4 years of remaining depreciable life. The repair cost was inappropriately capitalized. Green Co. reported operating income of $169,000 for the current year.

Required:

a. Assuming that Green Co. took a full year's straight-line depreciation expense in the current year, calculate the operating income that should have been reported for the current year.

b. Assume that Green Co.'s total assets at the end of the prior year and at the end of the current year were $946,000 and $1,017,000, respectively. Calculate ROI (based on operating income) for the current year using the originally reported data and then using corrected data. (Round your answers to 1 decimal place.)

c. Indicate the effect on ROI of subsequent years if the error is not corrected.

The Motor Trend Car Road Tests dataset (mtcars.csv) contains the data extracted from the 1974 Motor Trend US magazine and comprises fuel consumption and 10 aspects of automobile design and performance for 32 automobiles (1973–74 models). The dataset contains 32 observations on 11 variables. Analyze the dataset according to the following steps:

1. Calculate sample mean and sample variance of each variable.

2. Calculate the sample variance-covariance matrix and the sample correlation matrix. What can you say about the variance-covariance matrix and correlation matrix? the file is in the link,

Question 6: In the following: a). Identify the claim and state H0 and Ha. b). Find critical value(s) and the rejection region(s). c). Find the standardized test statistic: t-score. d). Decide whether to reject or fail to reject null hypothesis. e). Interpret the decision in context of original claim. A magazine claims that the mean amount spent by a customer at Burger Stop is greater than the mean amount spent by a customer at Fry world. The results are given below. At α = 0.05 can you support the magazines claim? Assume the population variances are equal. Burger Stop Fry World x1 = 5.46$ x2 = 5.12$ s1 = 0.89$ s2 = 0.79$ n1 = 22 n2 = 30

Many accounting and accounting-related professionals are skilled in financial analysis, but most are not skilled in manufacturing. This is especially the case for process manufacturing environments (for example, a bottling plant or chemical factory). To provide professional accounting and financial ­services, one must understand the industry, product, and processes. We have an ethical responsibility to develop this understanding before offering services to clients in these areas. Write a one-page action plan, in memorandum format, discussing how you would obtain an understanding of key business processes of a company that hires you to provide financial services. The memorandum should specify an industry, a product, and one selected process and should draw on at least one reference, such as a professional journal or industry magazine.

It is estimated that professional cellists practice 3.7 hours per day, on average. It is known that cellists practice hours are normally distributed. To find out if this is true, 27 professional cellists are randomly selected by STRINGS magazine and asked about their practice time. The resulting average is 3.86 hours per day with a standard deviation of 1.2. Is there sufficient evidence to indicate that average cellist practice hours differs from 3.7 hours per day?   = 0.02.

A sports reporter for a local newspaper is working on a story about small college basketball players. A reporter for a major sports magazine found that large college basketball players score 25 points per game. The local paper reporter believes that small college players score more points per game than large college players. She watches several small college basketball games and follows 25 players. Those 25 players score an average of 27.3 points per game with a standard deviation of 1.25 points. At a significance level of .05, can the reporter conclude that small college basketball players score more points per game than large college players?
