CHEM 120 Introduction To general Organic, And Biological Chemistry with Lab week 4
Document Content and Description Below
Balance the equation: C3H8 + O2 → CO2 + H2O (6 points) Reactants: C: 3 H: 8 O: 6 Products: C: 3 H: 8 O: 6 C3H8 + 4 O2 → 3 CO2 + 4 H2O. For the balanced chemical reaction: 2 HCl + Mg(OH)2... → MgCl2 + H2 (a)Determine the MW of MgCl2. Show your work. (3 points) (b) Determine how many mols of HCl you would require to produce 20 grams of MgCl2. Show your work (3 points) (a) (Mg: 24.305g) + (Cl2: 35.45 * 2) = 95.211 g/mol (b) 20 g MgCl2 * (1 mol MgCl2 / 95.211 g MgCl2) * (2 mol HCl /1 mol MgCl2) = 0.42 mol HCl [Show More]
