What is the oxidation number of manganese in the permanganate ion (mno4 -)?
Marat540 [252]
Each oxygen will have the oxidation number (2-), and we know the total charge is 1-. We have four oxygen atoms per molecule, so we can set up the equation:
(charge on Mn) + 4(charge on O) = -1
(charge on Mn) + 4(-2) = -1
(charge on Mn) - 8 = -1
Charge on Mn = 7
The answer is C. 7

The presence of a large population of _____________ indicates water depleted of oxygen and a high level of organic pollution.
blondinia [14]

The presence of a large population of sludgeworms indicates water depleted of oxygen and a high level of organic pollution.

The sludgeworms Tubifex is harvested and sold as tropical fish food since it is common near sewer outlets and serves as a sign of water or organic pollution. Polychaetes are crucial in rearranging the silt on the ocean floor.

Organic contamination happens when too much organic material, such sewage or manure, gets into the water.

There will be more decomposers and sludgeworms in a pond as the organic content accumulates. These decomposers and sludgeworms develop quickly and consume a lot of oxygen as they do so.

Hence, Sludgeworms are a sign of an abundance of oxygen-depleted water and significant levels of organic pollutants.

Explain how the energy changes on a rollercoaster between potential energy and kinetic energy?
MrRissso [65]

When the roller coaster is going up the hill, the potential energy (stored energy) is increasing and once at the top of the hill the potential energy is at its highest point becuase the velocity Is almost zero. Once the rollercoaster falls and speeds down the hill, the potential energy is converting to kinetic energy because of the movement. Kinetic energy is moving energy and potential energy is stored energy.
