Which of the following is a good hypothesis? 

The size of atomic orbitals is associated with [1] quantum number, n. Angular momentum quantum number, l. is associated with [2] of orbitals.

When nutrient levels rise above natural levels for a body of water, an event called [answer1], it causes an algae bloom. The algae blocks [answer2], which kills some of the plants and algae at the bottom of the stream. At night, the algae stop doing photosynthesis and start to reduce the [answer3] in the water, which stresses fish and other aquatic organisms. When the dead plants and algae get broken down by [answer4], the factor from the previous sentence becomes even more depleted, which may kill animals living in the water. With more dead material in the water, the cycle may continue until the water is unlivable.

What is ΔH° for the following phase change? NaCl(s) → NaCl(l) Given data: Substance        ΔH°f (kJ/mol) NaCl (s)          – 411.12 NaCl (l)           – 385.92

What level of function will a person with a SCI to C1-3 most likely have?

Suppose that we have two countries the United States and South Korea with their respective production possibility curves with two goods: cars and medical devices.  The United States’ car intercept is 1,000,000 cars and its medical device intercept is 300,000 medical devices. The South Korean car intercept is 500,000 cars and its medical device intercept is 500,000 medical devices.  If the two countries decide to engage in trade which country should produce cars?

“The distribution of income should be left to the market” is an example of:

The economic decision rule is to undertake an action only when the marginal benefits of that action are greater than its total costs.

If a country has a comparative advantage in the production of a good, its resources are better suited to the production of that good than are the resources of other countries.

Suppose there is a two good economy that produces medical devices and computers.  Suppose the economy goes from 80 percent of its economy devoted to the production medical devices to 100 percent, and there is relatively large opportunity costs in terms of computer production.  What is the most likely cause of the relatively large opportunity costs in terms of computer production?
