 <span>The "REVERSIBLE" chemical reaction- 
A + B <--> C + D 
Kc = [C][D] / [A][B] = 6.8 
Concentration at the start and after equilibrium- 
[A] = 2.00 M --> (2.00 - X) M 
[B] = 2.00 M --> (2.00 - X) M 
[C] = 0.00 M --> X M 
[D] = 0.00 M --> X M 
6.8 = X^2 / (2.00 - X)^2 
take the square root of both sides- 
2.6077 = X / (2.00 - X) 
5.2154 - 2.6077 X = X 
5.2154 = 3.6077 X 
X = 1.4456 
at equilibrium- 
[A] = 0.55 M 
[B] = 0.55 M 
[C] = 1.45 M 
[D] = 1.45 M</span>

Determinants of Interest Rates The real risk-free rate is 4%. Inflation is expected to be 4% this year, 5% next year, and then 4
Mademuasel [1]

Answer:

Determinants of Interest Rates The real risk-free rate is 4%. Inflation is expected to be 4% this year, 5% next year, and then 4.5% thereafter. The maturity risk premium is estimated to be 0.0006 × (t - 1), where t = number of years to maturity. What is the nominal interest rate on a 7-year Treasury security?

The nominal interest rate = 8.86%.

Explanation:

Average inflation premium = (4%+5%+4.5%+4.5%+4.5%+4.5%+4.5%)/7 = 31.5%/7 = 4.50%

Maturity risk premium for 7 year bond = 0.0006 * (7-1) = 0.36%

Nominal interest rate = real risk free rate + inflation premium + maturity risk premium = 4% + 4.50% + 0.36% = 8.86%.

Therefore, the nominal interest rate for the question given = 8.86%.

One year ago, you purchased 100 shares of a stock. This morning you sold those shares and realized a total return of 8.2 percent
earnstyle [38]

Answer: e. sum of the dividend yield and the capital gains yields is 8.2 percent

Explanation:

The return of 8.2% that was realized is the sum of the dividend yield and the capital gains yield.

The dividend yield refers to the income earned from dividends issued by the company whose stock you owned divided by the stock price.

The capital yield is the change in price since you bought the stock for instance, buying the stock at a price of $15 and it is now worth $20.

These two yields will combine to give you the return of 8.2% that you realized.

If Keynes’ law applies during economic contractions and Say’s law applies during economic expansion, how will the three goals of
Lelu [443]

Answer:

Answer is option a, i.e. trade-offs and connections may differ in short run and the long run.

Explanation:

Keynes' law in economics and Say's law in economics are contradictory in their perspective. Where Keynes' law says that it is the demand that creates the supply, on the other hand, Say's law states that its the supply that tends to create the demand. But, we cannot neglect any of the above facts as demand and supply cant operate independently. So, on combining the two laws, we happen to take both the given laws into account. Also, it is found that Keynes' law is more appropriate and accurate for the short-run whereas, Say's law is for the long run. This thus creates trade-offs and connections that differ in the short-run and long-run by affecting the three important goals of macroeconomics, i.e. higher standard of living, low inflation, and low unemployment.
