So if we have 0.139 mols of glucose, we will have 0.833 mols of oxygen (0.139 x 6 = 0.834, but accounting for sig figs it becomes 0.833). Hope that helps. Comment ( 7 votes) Upvote Downvote Flag more
How much ammonia will form when 7g of nitrogen reacts with
WebDec 4, 2024 · Lets begin by first converting the units to something usable: moles! 12grams of hydrogen / (2grams/mol) {this is because hydrogen is diatomic in this equation} = 6 moles of H 2. Great something we can work with! Now … Web7g of nitrogen is 0.25mol of N2, so the reaction equation is: 0.25N2 (g) + 0.75H2 (g) = 0.5NH3 (g) Change in Free Energy: ΔG (20C) = -8.5kJ (negative, so the reaction runs) Change in Enthalpy: ΔH (20C) = -22.9kJ (negative, so the reaction is exothermic) This reaction produces 0.5mol of NH3 (g), which is 8.515g or 11.207L at STP Devesh Khanal 7g network inc
