Answer:
In soil air as in the atmosphere, nitrogen gas (dinitrogen) comprises about 78%. In the atmosphere, oxygen comprises about 21% and carbon dioxide comprises about 0.36%. However, in the soil air, oxygen usually is replaced by carbon dioxide, so both range from about 0.4% to 21%.
Explanation:
Answer:
See below in bold.
Explanation:
Nitrogen, Hydrogen and Oxygen are the elements present in ammonium nitrate.
The Molar Mass = 2N + 4H + 3 O
= 2*14.007 + 4*1.008 + 3*15.999
= 80.043.
Percentage of Nitrogen = (2 * 14.007) * 100 / 80.043
= 35.00 %.
Percentage of Hydrogen = (4* 1.008) * 100 / 80.043
= 5.04%.
Percentage of Oxygen = (3 * 15.999) * 100 / 80.043
= 59.96 %.
