In the process of photosynthesis, plants absorb the gas (1)______ and water vapor from the air, and harvest a small fraction of (2)_______ (potential/ radiant) energy from the sun, to build energy-rich molecules such as sugars and proteins. Photosynthesis occurs not only in plants, but also in many bacteria, algae, and protists.

2. The earth contains a mixture of minerals and moisture that make it a very good conductor of electricity. Therefore, it is possible to wire any circuit using the earth as the return path for the current. For example, to power a light-bulb connect the positive end of the battery to the light-bulb, the negative end of the battery to the ground, and the other end of the light bulb to ground as well. This is the top circuit illustrated....

In Part 2 of Lab 5 you will dissolve about 3 g of urea in 50.0 mL of water and use the change in temperature to determine Delta H degree_soln. Let's go through the calculations. Suppose you dissolve 4.72 g of a solid in 50.0 mL of water. You note that the temperature changes from 25.0 degree C to 28.3 degree C. What is the mass of the solution? Assume the density of water is 1.000 g/mL. g What is...

Questions 1. a. Carbon dioxide from the atmosphere will dissolve in a NaOH solution if it is left uncovered. How would this affect the molarity of NaOH? b. Why does your titrated solution turn from pink back to colorless after several minutes? 2. What is the difference between an equivalence point and an endpoint? 3. Phenolphthalein actually changes color at around pH 9. Why, then, is it a suitable indicator for the titrations you did today?

6. Many IVPs are autonomous, meaning the independent variable doesn't appear explicitly on the right hand side. Such is the case for the differential equation describing the velocity of a falling object: In this autonomous equation, g is the acceleration due to gravity (32 ft/s2). The first term on the right hand side models the air resistance or drag on the object, and k is a constant that depends on the shape and size of the falling object. The choice...
