Methane CHis a simple organic molecule that is used as a fuel—it is the major component of natural gas. The bottom of the ocean contains large amounts of methane hydrate (also called methane ice or methane clathrate), enough that it has been suggested as a major source of fuel. The methane hydrate contains 6 moles water for each mole of methane. What percentage of methane hydrate is methane? blank1 - Numeric Answer % What percentage is water? blank2 - Numeric Answer %

The Chemistry of Crop Rotation Background Information: Plants need nitrogen to make amino acids, but they can't use the N2 in the air, which is why farmers and gardeners often turn to fertilizer. Fertilizer is made up of sources of nitrogen that the plant can use, among other things. One of the most common components used is ammonium nitrate, because of its high percent composition of nitrogen and because all of that nitrogen is in forms that the plant can use. 1. Find the formula and molar mass for ammonium nitrate. Formula: Molar mass: 2. What is the percent composition of nitrogen in ammonium nitrate? Answer:
