Answer: (4) the energy released or absorbed during the reaction

Explanation: Potential energy diagram is the representation of energy with the course of reaction. It shows the energy of reactants, activation energy which is the energy required by the reactants to cross the energy barrier and the energy of the products.

Thus the difference of energy of products and energy of reactants gives us the energy released or absorbed during the reaction.

\Delta H=E_P-E_R

where \Delta H = enthalpy of reaction

E_P = energy of products

E_R = energy of reactants

If E_P > E_R , energy is absorbed and reaction is endothermic

E_P < E_R , energy is released and the reaction is exothermic.

marishachu [46]

Answer:

Below is the clarification of that same particular question.

Explanation:

  • Le Chatlier's theory states that whenever an equilibrium mechanism is disrupted by environmental influences, the program responds by changing the supplies information of its constituents in a somewhat way that the disturbance is invalidated and reaches a stable equilibrium during that disrupted stage, with concentrations of stability differently than ever before.
  • Bromothymol blue seems to be a phenolic subs lone which always allows it to act throughout aqueous solutions as an acidic solution. Being such an acid (weak), it should not add to rapid, as well as introduces a balance with its accompanying but mostly disconnected form.

<u>For that kind of weak diprotic predictor, the standard economic statement can indeed be published as:</u>

    ⇒  H_2In_(aq)\rightleftharpoons In^{2-} +2H^+

  • It could be conclusively proven from either the theory of Le Charlier whereby, that whenever a strong acid becomes applied, the full disorientation of one or the other, through equilibrium formation, induces an increase throughout the medium's proton concentrations.
  • Likewise, it absorbs the protons throughout the media to split water that whenever a solution is added. So, particle concentration throughout the medium is decreasing. To accommodate for this transition, the equilibrium reacts by moving to the correct i.e. causing further dissociation of the optimistic predictor into their dianion through protons, thereby attempting to nullify that perturbation.

What does the nucleus do
mel-nik [20]
<span>The nucleus is the organelle present in eukaryotic cells with the main function in the control of all cell activities and maintaining the gene integrity. Namely, it contains the genetic material of the cell in the form of chromosomes (DNA molecules in complex with proteins). It is enclosed by the nuclear membrane which regulates the movement of proteins and RNA in and out of the nucleus.</span>

Solid lithium chloride decomposes into chlorine gas and solid lithium. Write a balanced equation.
quester [9]
<span>Lithium chloride is LiCl (because the valence of lithium is +1 and the valence of chlorine is -1). So the chemical equation is: Li Cl(s) ----> Li(s) + Cl2 (g). To balance the equation you need to multilply both Li Cl (s) and Li(s) by two, and then you finally get the balanced equation: 2 LiCl ---> 2 Li(s) + Cl2(g). Note that the number 2 to the right of Cl is a subscript.</span>
