Which metal can be used as a sacrificial electrode to prevent the rusting of an iron pipe? auau cucu mnmn agag
Cerrena [4.2K]

Mn metal can be used as a sacrificial electrode to prevent the rusting of an iron pipe. So, the correct option is (c) Mn.

Commonly, sacrificial electrodes are employed to stop another metal from corroding or oxidising. A metal that is more reactive than the metal being shielded must serve as the sacrificial electrode. Magnesium, aluminium, and zinc are the three metals most frequently used in sacrificial anodes.

Manganese-Magnesium (Mn-Mg) electrode is more suited for on-shore pipelines where the electrolyte (soil or water) resistivity is higher since it has the highest negative electropotential of the three. In order to replenish any electrons that could have been lost during the oxidation of the shielded metal, the highly active metal offers its electrons.

Therefore, Mn metal can be used as a sacrificial electrode to prevent the rusting of an iron pipe. So, the correct option is (c) Mn.

Potential energy due to the position of an object above earth surface is called
KengaRu [80]

ANSWER:

Potential energy due to the position of an object above Earth's surface is called gravitational  potential energy.

EXPLANATION:

Gravitational energy is the potential energy compared with gravitational force, as work is  needed to further things against Earth’s gravity. The potential energy due to high positions is  called gravitational potential energy, and is evidenced by water in an elevated storage or kept  behind a dam. If an article falls from one point to different point inside a gravitational field, the  force of gravitation will do actual work on the object, and the gravitational potential energy will  decrease by the same amount.

The reason an increase in substrate concentration does not increase the reaction rate indefinitely is because
scoundrel [369]

Answer:

Increasing substrate concentration also increases the rate of reaction to a certain point. Once all of the enzymes have bound, any substrate increase will have no effect on the rate of reaction, as the available enzymes will be saturated and working at their maximum rate.

How much does the air weigh within a column that is 1 square inch in area that extends from sea level all the way to the top of
fredd [130]

Answer:

14.7 lbs

Explanation:

Air pressure is the weight of the air above us. It is approximately 14.7 pounds or lbs per square inch at sea level. It means that an air column weights 14.7 lbs, 1 square inch in diameter, reaching all the way up to the top of the atmosphere.
