Explanation:
Answer:
C) 3
Explanation:
Given data;
Number of moles of oxygen produced = ?
Moles of KClO₃ decomposed = 2 mol
Solution:
Chemical equation;
2KClO₃ → 2KCl + 3O₂
Now we will compare the moles of KClO₃ with O₂
KClO₃ : O₂
2 : 3
Thus, 3 moles of oxygen are produced.
Answer:
C. attaching an active metal to make the pipe the cathode in an electrochemical cell.
Explanation:
Cathodic protection is a technique which helps in controlling the increased rate of corrosion of a metal surface by making it the cathode of an electrochemical cell. It connects the metal to be protected to a more easily corroded which is usually referred to as the sacrificial metal to act as the anode.
This technique preserves the metal by providing a highly active metal that can act as an anode and provide free electrons. By introducing these free electrons, the active metal sacrifices its ions and keeps the less active steel from corroding.
