Free_Kalibri [48]

Answer:

A compound that is being oxidized loses at least one electron, while a compound that is reduced gains at least 1 electron. To remember the difference, a mnemonic device such as OIL (oxidation is lost), RIG (reduction is gained) is helpful. Oxidation-reduction reactions are illustrated in the figure below.

Explanation:

A compound that is being oxidized loses at least one electron, while a compound that is reduced gains at least 1 electron. To remember the difference, a mnemonic device such as OIL (oxidation is lost), RIG (reduction is gained) is helpful.

Select the correct answer.
Rufina [12.5K]

Answer: Hey again!

Option (a) is the correct answer.

Explanation:

Elemental form of carbon means the pure form of carbon, that is, carbon is present in its natural form.

An elemental form also means that the pure atoms are not attached to any other atom.

For example, diamond is an allotrope of carbon in which there are only carbon atoms attached to each other and no other atom is present in it.

Whereas methane has carbon and hydrogen atoms attached to each other therefore, it is not an elemental carbon. And proteins include different atoms attached to each other.

Thus, we can conclude that diamond is an example of elemental carbon.

A student made a model of an onion skin cell she viewed
Komok [63]

If a student made a model of an onion skin cell using a microscopic magnification scale of 500:1 and the length of the modeled cell is 15 cm, the real cell's length would be 0.03 cm.

The scale is 500:1. This means that the dimension of the real cell without being magnified under the microscope would be 1/500.

Thus, if the length of the cell under the microscope is 15 cm. This length has been multiplied by 500. In order to get the real length, it must be divided by 500.

              15 x 1/500

                             = 0.03 cm
