<span>The answer is electrolysis. This is the chemical reaction that decomposes a substance (usually while in its liquid state) to its components by passing an electric current through it. Electrolysis of water is used to produce hydrogen fuel and also produce oxygen that can be used to supplement breathable air such as in submarines. </span>

Decomposition is the example of a reaction in which hydrogen and oxygen are produced by running an electric current through water.

Decomposition of water through electrolysis of water into oxygen and hydrogen gas due an electric current passed through water. when an electric current is passed through water, oxygen gas is being produced at the anode and hydrogen gas is produced at the cathode.

Consider the following reaction at constant pressure. Use the information provided below to determine the value of ΔS at 473 K.

Elis [28]

Answer:

The reaction will be spontaneous

Explanation:

To determine if the reaction will be spontaneous or not at this temperature, we need to calculate the Gibbs's energy using the following formula:

$\Delta G= \Delta H - T * \Delta S$

<u>If the Gibbs's energy is negative, the reaction will be spontaneous, but if it's positive it will not.</u>

Calculating the $\Delta G= -1267 - 473 K* \Delta S$ :

$\Delta G= -1267 - 473 K* \Delta S$

Now, other factor we need to determine is the sign of the S variation. When talking about gases, the more moles you have in your system the more enthropic it is.

In this reaction you go from 7 moles to 8 moles of gas, so you can say that you are going from one enthropy to another higher than the first one. This results in: $\Delta S>0[/tex}Back to this expression: [tex]\Delta G= -1267 - 473 K* \Delta S$

If the variation of S is positive, the Gibbs's energy will be negative always and the reaction will be spontaneous.

An ionic bond can be formed when one or more electrons are:

Mashutka [201]

D - for example, Potassium has 1 electron on its outer shell, whilst Chlorine has 7 electrons on its outer shell. Potassium loses one electron to Chlorine so that each of them have a full outer shell. This would form Potassium Chloride.

PLEASE HELP

Olenka [21]

There is no reaction because of the common ion effect(which in this case is K)if there were a reaction the products would be the same as the reactants so no reaction happens
