The correct answer for the question that is being presented above is this one: "2. are equal to the concentrations of the products." Given the reaction: HC2H3O2(aq) + H2O ↔ H3O+(aq) + C2H3O2-(aq) When the reaction reaches a state of equilibrium, the concentration of product is equal yo the reactant.<span> </span>
The answer is liquid.
it's pretty straight forward but for an explanation; it can't be solid because although the particles are close in solid, it follows a particular order. as for gas, they don't follow any sort of pattern but the particles are spread apart. i doubt you're learning about plasma in elementary school so that crosses that out.
