For a reaction system at equilibrium, LeChatelier's principle can be used to predict the A) activation energy for the system B)
SCORPION-xisa [38]

For a reaction system at equilibrium, LeChatelier's principle can be used to predict the "effect of a stress on the system".

<u>Option: C</u>

<u>Explanation:</u>

Le Chatelier's theory can be implemented to forecast a system's behavior due to variations in pressure, temperature, or concentration that will lead in predictable and contested variations in the system adjustments to establish a new state of equilibrium. This means that adding heat to a process would favor the endothermic path of a reaction, because this decreases the amount of heat generated in the system.

Here shift in equilibrium take place when volume increase, the total pressure decreases, which have potential to reverse the reaction, while on increasing pressure of system, the total volume decreases of the gaseous system, which can shift an equilibrium in the direction of the fewer molecules.

Imagine that you have many U-235 atoms and you fire a neutron at one of them. What do you think will happen?
Damm [24]

The correct answer is Release of large amount of heat and radiation.

U-235, which makes up just over 0.7% of natural uranium, is relatively uncommon; uranium is nearly 100 times more frequent than silver.Because uranium-235, one of the radioactive metal's isotopes, is the only naturally occurring isotope capable of supporting a nuclear fission process, radioactive metal is special. Nuclear power facilities, as well as the nuclear reactors that power ships and submarines, can be powered by uranium that has been "enriched" to have a higher proportion of U-235. In nuclear weapons, it can also be applied. Examples of extremely unstable fission fragments produced by uranium-235 fission events caused by neutron absorption include the barium and krypton nuclei. These pieces nearly instantly split into barium-144 and krypton-89 by releasing three neutrons between them.

Answer: The positively charged ions will be attracted to the negative electrode and gain electrons. Meanwhile, the negatively charged ions will be attracted to the positive electrode and release electrons.

Explanation:

Electrolysis is breaking down of a substance into its constituents by the action of electrical current.  

LiCl\rightarrow Li^++Cl^-

Cations wich are positively charged specie moves towards the negatively charged electrode that is towards the cathode. On reaching cathode, cations accepts electrons and get reduced through reduction reaction.

Li^++e^-\rightarrow Li

Anions wich are negatively charged specie moves towards the positively charged electrode that is towards the anode. On reaching anode, anions donate electrons and get oxidized through oxidation reaction.

Cl^-\rightarrow Cl+e^-
