The conversion factors are different because the stoichiometries of the balanced chemical reactions are different. Why are the ratios between H 2 and O 2 different? Construct the three independent conversion factors possible for these two reactions:.If 45,750 molecules of SF 6 are needed, how many molecules of F 2 are required? One way to make sulfur hexafluoride is to react thioformaldehyde, CH 2S, with elemental fluorine:. ![]() Suppose we need to make 145,000 molecules of Fe 2(SO 4) 3. How many molecules of CuS are formed if 9,044 atoms of H react?įor the balanced chemical equation Fe 2O 3(s) + 3SO 3(g) → Fe 2(SO 4) 3 How many molecules of Fe 2(SO 4) 3 are produced if 321 atoms of S are reacted?įor the balanced chemical equation CuO(s) + H 2S(g) → CuS + H 2O(ℓ) Given the balanced chemical equation Fe 2O 3(s) + 3SO 3(g) → Fe 2(SO 4) 3 How many molecules of CO 2 are produced when 56 molecules of C 6H 6 react? How many molecules of H 2O are produced when 75 molecules of H 2O 2 react?įor the balanced chemical reaction 2C 6H 6(ℓ) + 15O 2(g) → 12CO 2(g) + 6H 2O(ℓ) How many molecules of O 2 are needed when 38 atoms of S react?ĦH +(aq) + 2MnO 4 −(aq) + 5H 2O 2(ℓ) → 2Mn 2 +(aq) + 5O 2(g) + 8H 2O(ℓ).Given the chemical equation: S(s) + O 2(g) → SO 3(g). ![]()
