Ytu perform an electrolysis reaction using FeCl, iron (1) chloride. Which of the following will happen?
1 answer:
Answer:
The answer is "Option B"
Explanation:
when we react with FeCl, iron, and chloride to both the electrolysis. So, iron is charged positive ion, as well as passes to the negative, is cathode electrode. But there is a decrease in the cathode.
The equation can be defined as follows:
In the above equation, when the iron chloride electrolysis solution, it will give the iron(II) and the chlorine. This process happens when the hydrogen chloride solution at a temperature of about 90 ° C.

<h3>What is electrolysis?</h3>Electrolysis is the process by which electric current is passed through a substance to effect a chemical change.
The mass of aluminium oxide Al₂O₃ = 2000 kg = 2000 000 g
Molar mass of Al₂O₃ = 101.96 g/mol
no of moles =
no of moles of Al₂O₃ =
no of moles of Al₂O₃ = 19615.4 mol
From the reaction:
4Al + 3O₂ ⇒ Al₂O₃
To determine the moles of O₂ in Al₂O₃:
Then;
19615.4 mol X mol of O₂ = 29423.1
The mass of oxygen now = 29423.1 × 32 g
= 941539.2 g
Hence, 941539.2 g of mass of oxygen is produced when 2000 kg of aluminium oxide is completely electrolysed.
