Hydrogen
Ammonium sulfate = (NH4)2SO4Nitrogen atoms = 2Hydrogen atoms = 8Sulfur atoms = 1Oxygen atom = 4Total atoms = 15
Assume those percentages as mass. Find moles. 30 grams Nitrogen (1 mole N/14.01 grams) = 2.141 moles ( call it 2 ) 70 grams oxygen (1 mole O/16.0 grams) = 4.4 moles ( call it 4 ) smallest mole number is 1 in formula and divide larger number by it 2/4 = 2 so.............. NO2 nitrogen dioxide is the empirical formula
2 hydrogen and 1oxygen
Nitrogen is represented in the highest percentage by volume in dry air, at approximately 78%. Oxygen is the next most abundant gas in the atmosphere, at around 21%. Carbon dioxide is present in a much lower percentage, around 0.04%. Hydrogen is present in trace amounts in the atmosphere.
One carbon atom and one oxygen atom combine to produce one carbon monoxide (C0) molecule.
the answer is ozone...O3 water vapour (2 hydrogen, 1oxygen)
2Hydrogen+1oxygen ---> water(H20) When 2 atoms of hydrogen reacts with 1 atom of oxygen then a molecule of water form.

Covalent bonds typically form between nonmetals, resulting in the formation of molecules. The particles formed by covalent bonds are individual molecules, which are made up of two or more atoms that share electrons. Covalent bonds are characterized by the sharing of electron pairs between atoms.
Na2O is sodium oxide. It contains the elements, sodium and oxygen. The chemical formula tells us that there are 2 sodium atoms and 1oxygen atom . It is a highly reactive compound, which will readily dissolve in water to form sodium hydroxide. Na2O + H2O = 2NaOH .
For the oilMineral oil has a density of around 0.8 g/cm3, "good" crude oil of around 0.8 - 0,83 g/cm3 and "heavy" crude oil is above 0,92 g/cm3Crude oil consists (by weight) of 83% to 87% carbon.One barrel is about 159 liters. Assuming a density of 0,85g/cm3 for our oil we would end up with 135 kg of oil, which contains on the higher end (87% carbon) 118 kg of carbon.For the carbon dioxide:Carbon Standard atomic weight: 12.0107(+/- 0.00008) g·mol−1Oxygen Standard atomic weight: 15.9994(+/- 0.00003) g·mol−1Lets say: Carbon = 12 and 2 x Oxygen = 2 x 16 = 32 => Total: 44(12/44 = 27.27% of Carbon in CO2)---------------------------------Assuming that all the carbon will find its oxygen to form CO2, that would be 433 kg of carbon dioxide.With above assumptions:1 barrel of oil could produce 433 kg of carbon dioxide.(Ignoring all other side products)Sources:http://en.wikipedia.org/wiki/Oxygenhttp://en.wikipedia.org/wiki/Carbonhttp://en.wikipedia.org/wiki/Mineral_oilhttp://en.wikipedia.org/wiki/Crude_oilhttp://en.wikipedia.org/wiki/API_gravity#Classifications_or_grades
