Ch100: Fundamentals for Chemistry 1Ch 6: Balancing Chemical ReactionsA) What factors determine the rate of a chemical reaction?B) What is the role of a catalyst in a chemical reaction?C) Sketch a simple energy diagram for an exothermic reaction?D) Sketch a simple energy diagram for an endothermic reaction?1. When sodium hydrogen carbonate (sodium bicarbonate) NaHCO3 is heated strongly in a test tube, carbon dioxide gas, CO 2, water vapor, H2O, are evolved from the test tube, leaving a residue of sodium carbonate, Na2CO3. a) Write the unbalanced chemical equation for this process.b) Write the balanced chemical equation for this process.2. Boric acid, H3BO3, is produced by treating borax (Na2B4O7) with aqueous sulfuric acid and water. Sodium sulfate is a by-product of this process. a) Write the unbalanced chemical equation for this process.b) Write the balanced chemical equation for this process.3. When sulfuric acid is added to ordinary table sugar (sucrose), C12H22011, a long black snake of elemental carbon forms, with the release of a cloud of steam (water vapor). a) Write the unbalanced chemical equation for this process.b) Write the balanced chemical equation for this process.Ch100: Fundamentals for Chemistry 2Ch 6: Balancing Chemical Reactions4.
