N2 + 3H2 → 2NH3. 2FePO4 + 3Na2SO4 -->Fe2(SO4)3 + 2Na3PO4 What is the theoretical yield of Fe2(SO4)3 if
Are my answers to these Chemistry problems correct? For the following questions, use the following: Tungsten metal is manufactured by the reaction of Tungsten Trioxide (WO3) with Hydrogen (H2).154 for the reaction N2(g) + 3H2(g)⇄2NH3(g).
Since there is an equal number of each element in the reactants and products of 2Fe + 6HC2H3O2 = 2Fe(C2H3O2)3 + 3H2, the equation is balanced..75 grams of N2, producing 1. a. Reactant.
The reaction that does not represent the oxidation reduction has been the reaction of NaCl with . 3H2 (g) + N2 (g)→NH3 (g) If three molecules of hydrogen react with one molecule of nitrogen, how many molecules of ammonia would be formed? 2. This allows you to write an equilibrium expression specific to this reaction.
Step 4: Substitute Coefficients and Verify Result. C) the noble gases react with other compounds to get eight valence electrons.105 .Explanation:Ammonia is an essential industrial chemical used in the production of fertilizers, nylon, and other chemicals. Min's result: Ca3P2 + H2O → Ca3 (OH)2 + PH3. 3H2+N2↽−−⇀2NH3 What substances are present in the reaction mixture when equilibrium has been obtained?, Write the equilibrium‑constant
