Given the following thermochemical equations:

X₂+3Y₂ equals 2XY₃ and Delta H =-340 kJ

X₂+2 Z₂ equals 2XZ₂ and Delta H = -170 kJ

2Y₂ + Z₂ equals 2Y₂Z and Delta H=-260kJ

Calculate the change in enthalpy for the following reaction

4XY3+7 Z₂ equals 6Y₂Z+4XZ₂

Chamberlain Enterprises Inc. reported the following receivables in its December 31, 2021, year-end balance sheet:

Additional Information:

1. The notes receivable account consists of two notes, a $100,000 note and a $270,000 note. The $100,000 note is dated October 31, 2021, with principal and interest payable on October 31, 2022. The $270,000 note is dated June 30, 2021, with principal and 6% interest payable on June 30, 2022.
2. During 2022, sales revenue totaled $1,450,000, $1,335,000 cash was collected from customers, and $33,000 in accounts receivable were written off. All sales are made on a credit basis. Bad debt expense is recorded at year-end by adjusting the allowance account to an amount equal to 10% of year-end accounts receivable.
3. On March 31, 2022, the $270,000 note receivable was discounted at the Bank of Commerce. The bank's discount rate is 10%. Chamberlain accounts for the discounting as a sale.

On a frictionless surface, a block of mass m1 and velocity v1 = vi is moving to the right when it collides with a spring, of spring constant k, attached to the left side of a stationary block of mass m2. Both blocks are free to slide on the surface.

(a) Argue either from physical principles or with equations that the velocities of the two blocks are the same when the spring is at its maximum compression.

(b) What is the maximum compression of the spring, xmax?
(c) In terms of m1,m2, and v, what are the final velocities of the two blocks after

they finish interacting?

In an experiment designed to measure the speed of light, a laser is aimed at a mirror that is 52.0 km due north. A detector is placed 107 m due east of the laser. The mirror is to be aligned so that light from the laser reflects into the detector.

(a) When properly aligned, what angle should the normal to the surface of the mirror make with due south?

(b) Suppose the mirror is misaligned, so that the actual angle between the normal to the surface and due south is too large by 0.005

Research consistently shows that living in poverty negatively influences language development. Locate and summarize information that would support this assumption (e.g., journal articles, Centers for Disease Control [CDC], and/or World Health Organization [WHO]). What types of experiences or resources do you feel that children who live in poverty do not experience or receive but children from higher economic statuses benefit from?

In the earth's reference frame, a tree is at the origin and a pole is at x=31km. Lightning strikes both the tree and the pole at t=13?s. The lightning strikes are observed by a rocket traveling in the x-direction at 0.6 c.

What are the spacetime coordinates x? tree, x? pole for these two events in the rocket's reference frame?

What are the spacetime coordinates t? tree, t? pole for these two events in the rocket's reference frame?

Square Manufacturing is considering investing in a robotics manufacturing line. Installation of the line will cost an estimated $10.5 million. This amount must be paid immediately even though construction will take three years to complete (years 0, 1, and 2). Year 3 will be spent testing the production line and, hence, it will not yield any positive cash flows. If the operation is very successful, the company can expect after-tax cash savings of $7.5 million per year in each of years 4 through 7. After reviewing the use of these systems with the management of other companies, Square’s controller has concluded that the operation will most probably result in annual savings of $4.9 million per year for each of years 4 through 7. However, it is entirely possible that the savings could be as low as $3.3 million per year for each of years 4 through 7. The company uses a 14 percent discount rate. Use Exhibit A.8.

Hank, a calendar-year taxpayer, uses the cash method of accounting for his sole proprietorship. In late December, he performed $28,000 of legal services for a client. Hank typically requires his clients to pay his bills immediately upon receipt. Assume his marginal tax rate is 32 percent this year and will be 35 percent next year, and that he can earn an after-tax rate of return of 12 percent on his investments. Use Exhibit 3.1.

a. What is the after-tax income if Hank sends his client the bill in December?

b. What is the after-tax income if Hank sends his client the bill in January? (Do not round intermediate calculations. Round your answer to the nearest whole dollar amount.)
