WebIn the compound hydrogen sulfide, H2S , the two hydrogen atoms have an oxidation number of +1 , for a total of +2 . Therefore, the oxidation number of sulfur in the compound is -2 , and the sum of the oxidation numbers is 0 . 4. Pollution most sulfur oxides are produced by burning: Answer: WebTerms in this set (93) How many carbon atoms are present in 0.92 moles of CH3? 1.66 x 1024 atoms. How many moles are in 1.16 x 1025 atoms of H2CO3? 19.3 moles of H2CO3. How many atoms of Hydrogen atoms are found in 3.94 mol of NH5? 1.19 x 1025 Hydrogen Atoms. How many molecules are in 3.9 moles of water? WebMr of NH3 = 14 + 3 = 17 Mass of NH3 produced = 17 X 7.02 = 119.34 gramsfirst you need the balanced equation N2 + H2 = NH3 we need it balanced N2 + 3H2 = 2NH3 now we have it balanced we have excess H2 so it doesnt play anything in the equation... taribul malgesso
