Consider the reaction:
Br2(g)+Cl2(g)⇌2BrCl(g)
Kp=1.11×10−4 at 150 K.
A reaction mixture initially contains a Br2 partial pressure of 785
torr and a Cl2 partial pressure of 725 torr at 150 K.
Calculate the equilibrium partial pressure of BrCl.

For any variable X,
ΔX = “change in
X ”, Δ is the Greek (uppercase) letter
delta, Examples: If ΔL = 1 and
ΔK = 0, then ΔY
= MPL.
More generally, if ΔK = 0, then
Δ(Y − T ) =
ΔY − ΔT , so
ΔC = MPC ×
(ΔY −
ΔT ) = MPC
ΔY − MPC
ΔT
Now Suppose MPC = 0.8 and
MPL = 20. For each of the following,
compute ΔS:

You own a stock portfolio invested 15% in Stock Q, 15% in Stock
R, 20% in Stock S, and 50% in Stock T. The betas for these four
stocks are 0.84, 1.17, 1.08, and 1.36, respectively. What is the
portfolio beta? (Do not round intermediate calculations. Round the
final answer to 3 decimal places.)

Two protons are initially moving towards each other with equal
speeds in the laboratory. They continue to exist after experiencing
a head-on collision that also produces a neutral pion of rest
energy 135 MeV. If the protons and the pion are all at rest after
the collision, find a) the initial kinetic energy of the protons,
and b) the initial speed of the protons.

Suppose you’re evaluating a new project costing 125 and yielding
an expected payoff of 75 for the two subsequent years.
You know that the market(portfolio) rate is 0,10 that the
covariance of the new investment’s payoff with the market portfolio
is 0,2 and that the variance of the market payoff is 0,1.
You also know that the risk-free rate is 0,05. Would you accept
the project if you do not account for the risk embodied in the new
project? Why?...

An appliance dealer sells three different models of upright
freezers having 13.5, 15.9, and 19.3 cubic feet of storage space.

A medical researcher believes that a drug changes the body's
temperature. Seven test subjects are randomly selected and the body
temperature of each is measured. The subjects are then given the
drug, and after 30 minutes, the body temperature of each is
measured again. The results are listed in the table below. Is there
enough evidence to conclude that the drug changes the body's
temperature? Let d=(body temperature after taking drug)−(body
temperature before taking drug). Use a significance level of...

Three identical very dense masses of 6500 kg each are placed on
the x axis. One mass is at x 1 = -140 cm , one is at the origin,
and one is at x 2 = 390 cm .

Fgrav on the mass at the origin due to the other two
masses?
Take the gravitational
constant to be G = 6.67×10?11 N?m2/kg2 .

For one approach to this problem, consult Interactive
LearningWare 24.1. For each of the three sheets of polarizing
material shown in the drawing, the orientation of the transmission
axis is labeled relative to the vertical. The incident beam of
light is unpolarized and has an intensity of 1230 W/m2. What is the
intensity of the beam transmitted through the three sheets when 1 =
15.2°, 2 = 53.2°, and 3 = 95.4°?

9.3 A 60 W incandescent bulb costs $0.36 and lasts 1,000 hr; a
14 W CFL bulb costs $4 and lasts 10,000 hr; and a 9.5 W LED bulb

of using incandescent bulbs for 25,000 hr. (Note: the cost includes
the initial cost of the bulbs plus the energy used for 25,000 hr.)
B. Find the cost of using CFLs for 25,000 hr. How much money is...

The London Eye, one of the largest Ferris Wheels, was recently
built near the bank of the river Thames in London. It has a
