The table below shows the most common prefixes and their relative magnitudes. Note that web browsers do not support use of superscripts and subscripts very well, so the notation 10^ 2 means 10 to the power of 2, or 10 squared.Similarly, the notation 10- 2 should be read as 10 to the power of -2.lways put a space between the number and unit, e.g., 203.65 m, 457 um pH: The proper method for reporting pH is to place the unit before the number (pH 7); never insert the word of between the unit and number and avoid splitting the unit and number within a sentence-they should always go together.
What elements make up the gas compounds found in the atmosphere? The atmosphere is primarily composed of Nitrogen (N2), which accounts for 78%. Oxygen follows, accounting for 20% of its volume, with argon less than 1%. The remainder is compâ¦osed of particulates and trace gases, including water vapor.
Table 7a-1 lists the eleven most abundant gases found in the Earth's lower atmosphere by volume. Of the gases listed, nitrogen, oxygen, water vapor, carbon dioxide, methane, nitrous oxide, and ozone are extremely important to the health of the Earth's biosphere.The table indicates that nitrogen and oxygen are the main components of the atmosphere by volume.f the gases listed, nitrogen, oxygen, water vapor, carbon dioxide, methane, nitrous oxide, and ozone are extremely important to the health of the Earth's biosphere.
