Answer:
Explanation:
The answer choices are:
<h2>Solution</h2>
You must use the conversion factors to convert J to kcal.
Dividing both sides by 4.184J:
⇒ 1 = 1cal/4.184J
Dividing both sides by 1,000 cal
⇒ 1 = 1kcal / 1,000 cal
Mutiply<em> 578J</em> by the conversion factors to find <em>kcal</em>:
Notice how the units J and cal cancel to yield kcal at the end.
23.934 Hours Is how long it tales.
<em>The cathode is Y</em>
<h3><em>
Further explanation</em></h3>
Electrolysis uses electrical energy to carry out redox reactions that are not spontaneous.
The ions in the solution flowing electrically will move towards to opposite charge of the electrode
The electrolysis material is an electrolyte which can be a solution or a melt.
In positive pole electrolysis cells - the anode is the site of the oxidation reaction, while the negative pole - the cathode is the reduction reaction site.
The result of the reaction in the anode is based on a substance that easily oxidized while the reaction in the cathode is based on a substance that easily reduced.
Electrons (electricity) enter an electrolysis cell through the negative pole (cathode)
The negative ion from the solution will move towards the positive electrode and release the electrons around the positive electrode (oxidation) and the electrons flow to the negative pole
Whereas around the negative electrode, there is electron binding and a reduction reaction occurs
So if we see the picture the cathode is Y
