Answer this M.C.Q When can you ignore the mass of a solid reactant for an enthalpy and/or solubility reaction? A. When it is very large B. You never have to take mass into consideration. C. Only when it is very small. D. Never

3, Reaction quotient is: Group of answer choices A, the concentration of the products raised to the stoichiometric coefficients divided by the concentration of the reactants raised to their stoichiometric coefficients, measured when concentrations are equal B, the concentration of the products raised to the stoichiometric coefficients divided by the concentration of the reactants raised to their stoichiometric coefficients, measured at any time during the course of the reaction C, the concentration of the reactants raised to the stoichiometric coefficients divided by the concentration of the products raised to their stoichiometric coefficients, measured at any time during the course of the reaction D, the concentration of the products raised to the stoichiometric coefficients divided by the concentration of the reactants raised to their stoichiometric coefficients, measured at equilibrium E. the concentration of the reactants raised to the stoichiometric coefficients divided…

A reaction occurs between hydrogen gas and chlorine gas. This causes their container to expand from 2 L to 12 L. The expansion causes the container to do 14 J of work. What was the pressure inside the container? Be sure to show all of your work and include the correct units.
