Final answer:
The major products of the reaction between HCl and NaOH are NaCl and H2O. The disproportionation reaction of Cl2 in basic solution forms Cl- and ClO3-. The exercises cover balanced chemical equations, Lewis diagrams, and acid-base reactions.
Step-by-step explanation:
The question is asking to determine the major product of a given reaction, which is a fundamental concept in chemistry related to stoichiometry and chemical equations. Given the reaction HCl + NaOH → NaCl + H₂O, the major products are Sodium chloride (NaCl) and Water (H₂O). Since both reactants are present in equal amounts (0.02 mol), they will react completely to form 0.02 mol of each product according to the balanced chemical equation. For the disproportionation reaction of molecular chlorine in basic solution, the balanced equation is 3Cl₂ + 6OH- → 5Cl- + ClO₃⁻ + 3H₂O, where chlorine is both oxidized to chlorate ions (ClO₃⁻) and reduced to chloride ions (Cl-). The exercise also includes writing balanced reactions for the combustion of hydrocarbons and the reaction of Al₂O₃ with HClO₄. Furthermore, the reactions of different organic compounds with HCl have been provided to illustrate the formation of acid salts.
