GRAPHING PRACTICE PROBLEMS Directions: All three graphs must be drawn on graph paper. Please use a ruler and be as
neat as possible. Please complete all questions in the spaces provided on this page.
Practice Problem 1: The following table shows the quantity of oxygen gas that can be obtained from the
electrolysis of various quantities of water. Draw a graph of the data, observing all the practices of good
graph construction. This includes: labeling each axis, scaling each axis appropriately, plotting the points
correctly, connecting the points, and giving the graph a title.
Quantity of water
3.0 grams
10.0 grams
18.0 grams
23.0 grams
28.0 grams
Quantity of Oxygen
2.7 grams
8.9 grams
16.0 grams
20.4 grams
24.9 grams
1. What is the independent variable?
2. On which axis will the independent variable be placed?
3. What is the dependent variable?
4. On which axis will the dependent variable be placed?
5. Predict how much oxygen could be obtained from 15 grams of water. How reliable is this prediction?
6. Predict how much oxygen could be obtained from 32 grams of water? How reliable is this prediction?

a fossil fuel is a fuel formed by natural processes, such as anaerobic decomposition of buried dead organisms, containing energy originating in ancient photosynthesis.[1] the age of the organisms and their resulting fossil fuels is typically millions of years, and sometimes exceeds 650 million years.[2] fossil fuels contain high percentages of carbon and include petroleum, coal, and natural gas.[3] other commonly used derivatives include kerosene and propane. fossil fuels range from volatile materials with low carbon to hydrogen ratios like methane, to liquids like petroleum, to nonvolatile materials composed of almost pure carbon, like anthracite coal. methane can be found in hydrocarbon fields either alone, associated with oil, or in the form of methane clathrates.

the theory that fossil fuels formed from the fossilized remains of dead plants by exposure to heat and pressure in the earth's crust over millions of years was first introduced by andreas libavius "in his 1597 alchemia [alchymia]" and later by mikhail lomonosov "as early as 1757 and certainly by 1763".[4] the first use of the term "fossil fuel" was by the german chemist caspar neumann, in english translation in 1759.[5]

in 2017 the world's primary energy sources consisted of petroleum (34%), coal (28%), natural gas (23%), amounting to an 85% share for fossil fuels in primary energy consumption in the world.[6] non-fossil sources in 2006 included nuclear (8.5%), hydroelectric (6.3%), and others (geothermal, solar, tidal, wind, wood, waste) amounting to 0.9%.[7] world energy consumption was growing at about 2.3% per year. in 2015 about 18% of worldwide consumption was from renewable sources.[8]

as the gila monster consumes the eggs or young of the desert cottontail and gambel's quail, thus its main food supply is only accessible for a restricted time duration every year. however, for this, the gila monsters exhibit three adaptations, which elevate their survival rate in the desert condition.  

first, is that they possess huge bodies, and can consume greater concentrations of food during a small period. secondly, they require to feed infrequently as they can accumulate fat in their tails. ultimately, their rate of metabolism is very low, so that they can burn their reservoirs of fat gradually.  

the three components of a nucleotide are the nitrogenous base, the phosphate group and the five-carbon sugar.
