1) Our first example is the reaction of ethanol, C2H5OH (a component In some gasoline mixtures) with oxygen. When ethanol is burned one molecule of ethanol combines with three oxygen molecules to form two CO, molecules and three H20 molecules. a) Draw two molecular sized models: one for the reactant mixture and one the product mixturel Use different colors or different shading to indicate the identity of the atoms. b) Write the balanced chemical equation for the reaction described. Check...

Stoichiometry (How are masses of reactants and products related?) Model 1: The Balanced Chemical Equation As we saw in ChemActivity 19. a balanced chemical reaction can be interpreted in two ways. First, it can describe how many molecules of reactants are consumed in order to produce a certain number of molecules of products. Second, it can describe how many moles of reactants are consumed in order to produce the indicated number of moles of products. | 3 H2 (9) +...

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...

Part A Determine the balanced chemical equation for this reaction. C8H18(g)+O2(g)?CO2(g)+H2O(g) Enter the coefficients for each compound in order, separated by commas. For example, 1,2,3,4 would indicate one mole of C8H18, two moles of O2, three moles of CO2, and four moles of H2O. 2,25,16,18 SubmitHintsMy AnswersGive UpReview Part Correct It is important to balance a chemical equation before using it for calculations. Checking that equations are balanced will help you avoid many errors in chemistry problems. Balanced chemical equation...
