4. Approximate the number of moles of hydrogen peroxide at the equivalence point in the graph in the introduction, supposing a 3.00% m/m solution. Thus the densities will be- Trial Mass(g) 0.448 0.450 3 Density(g/ml) 0.448 g/ 0.400 ml = 1.12 g/ml 0.450 g/ 0.400 ml = 1.125 g/ml 0.437 g/ 0.400 ml = 1.0925 g/m 0.442 g/ 0.400 ml = 1.105 g/ml...

Question 11 of 22 Write the balanced chemical equation for the combination (synthesis) reaction of magnesium with oxygen gas. Phases are optional equation If neither reactant is limiting and the reaction goes to completion, the mass of the product should be equal to the molar mass of the product. the mass of oxygen gas. O the mass of magnesium the sum of the mass of the reactants, BN M?? ?

Model 4: Using Moles of Limiting Reagent in Stoichiometry The above pictures are not realistic because they involve so very few molecules. In a "real-world" sample, you are likely to have on the order of 10 molecules. Consider the following: Suppose you have a reaction vessel initially containing 13.5 moles of sulfur dioxide and 11.2 moles of oxygen mol SO, required to react with all O2 = 11.2 mol O2 x 2 mol SO 22.4 mol SO, 1 mol O2...
