1. If good Z has an income elasticity of 1.0, then demand for good Z is income __________ and the good is __________.

inelastic, normal

elastic, normal

unit elastic, normal

inelastic, inferior

elastic, inferior

2. If two goods are substitute goods,

the price elasticity of demand for both goods will be less than 1.

an increase in the price of one will cause a decrease in the demand for the other.

the price elasticity of demand for both goods will be greater than 1.

an increase in the price of one will cause an increase in the demand for the other.

1.0 gram samples of solutes A,B, and C are dissolved in 10.00 g of water to give three separate solutions. Use the information below to calculate the molecular mass of A, B, and C. Determine the molecular formula of solution B. Assume all solutes are nonvolatile and nonelectrolytes. 1. Solute A has a vapor pressure of 16.9 torr at 20 degrees C. The Vapor pressure of water at 20 degrees C si 17.5 torr. Calculate Molecular mass. 2. Solute B freezes at -1.03 degrees C and has an analysis of 40% Carbon, 53.6% Oxygen, and 6.7% Hydrogen. The Kf (constant of Freezingpoint) for water is 1.86. What is the moleuclar mass and molecular formula? 3. Solute C has an osmotic pressure of 1.6 atm at 25 degrees C. What is the molecular mass of this substance?

A firm's assets have a beta of 1.0. Assuming that the debt beta equals 0.0 and that there are no taxes, calculate the firm's equity beta under the following assumptions:

a. The firm's capital structure is 100% equity.

b. The capital structure is 20% debt and 80% equity.

c. The capital structure is 40% debt and 60% equity.

d. The capital structure is 60% debt and 40% equity.

e. The capital structure is 80% debt and 20% equity.

Do you believe that the assumption of a zero debt beta is equally valid for each of these capital structures? Why or why not?

A sealed 1.0 L flask is charged with 0.500 mol of I₂ and 0.500 mol of Br₂. An equilibrium reaction ensues:  

I₂(g) + Br₂(g) ↔ 2 IBr(g).

When the reaction reaches equilibrium, the flask contains 0.640 mol of IBr. What is the value of the equilibrium constant K_c, for this reaction?

Type your answer in decimal number carrying only one digit after decimal. So you must round up or down at the second digit after decimal.

For example, your answer must be like 1.7, 2.3, 3.4, 4.2, 5.8, 6.6, 7.4, etc.
