J.J Thompson, by carrying out a series of experiments with a cathode ray, realized that electric charge is composed of many smaller particles; particles that are also smaller than atoms. The experiment showed that these particles are mobile; therefore, he proposed the idea that electrons are mobile in the atom. The answer is C

Which mathematical relationship allows calculation of the equilibrium constant of a reaction if you know the standard change in
Evgesh-ka [11]

Which mathematical relationship allows calculation of the equilibrium constant of a reaction if you know the standard change in Gibbs Free Energy ΔG is related to Q by the equation ΔG=RTlnQK. If ΔG < 0, then K > Q, and the reaction must proceed to the right to reach equilibrium

<h3>What is Gibbs Free Energy?</h3>

The maximum amount of work that may be accomplished by a thermodynamically closed system at constant temperature and pressure can be determined using the Gibbs free energy (also known as Gibbs energy; symbol: displaystyle G). Additionally, it offers a prerequisite for any processes like chemical reactions that might take place in such circumstances.

The maximum amount of non-expansion work that can be taken from a closed system (one that can interchange heat and work with its surroundings but not matter) at fixed temperature and pressure is known as the Gibbs free energy change, which is measured in joules in SI. This maximum is only possible with a fully reversible method.

Which change does not increase the speed of reaction between zinc and hydrochloric acid?
Mademuasel [1]
Any factor that causes molecules to collide more frequently speeds up the reaction rate. This is achieved by an increase of the reactants concentration, surface area, raised temp. , raised pressure of gaseous reactant, or an addition of catalysts to the reactant
