Final answer:
The question requires performing several tasks related to representing and understanding chemical reactions, including drawing molecular structures, balancing equations with state symbols, and constructing tables to show concentration changes as reactions proceed towards equilibrium.
Step-by-step explanation:
The question involves understanding and representing chemical reactions, where students are expected to complete various tasks. These tasks include drawing ball-and-stick models of the products, writing balanced chemical equations with state symbols, constructing tables showing concentration changes, and determining the direction of reaction towards equilibrium.
For instance, to complete the reactions by drawing the major product or products, a student would need to visualize the molecular structure of reactants and how they combine to form products, using ball-and-stick models to represent the bonds and atom positions.
Writing balanced chemical equations involves accounting for all atoms of each element on both sides of the reaction and affixing appropriate state symbols (solid, liquid, gas, or aqueous).
Constructing a table with initial and final concentrations involves understanding reaction stoichiometry and the extent to which a reaction proceeds, while factoring in changes in concentration as the reaction moves towards equilibrium.
Finally, determining the direction of the reaction towards equilibrium in various experiments requires understanding of reaction dynamics, Le Chatelier's principle, and equilibrium constants.
