Answer:
The answer is D) Electrolytic cell
Explanation:
An electrolytic cell is a device used for the decomposition by the electrical current of ionized substances called electrolytes.
When the two electrodes are connected by a wire, electrical energy is produced, and a flow of electrons takes place from the electrode.
These cells are the closest thing to a galvanic battery.
Answer:
d

Answer:
the number of protons in the nucleus of an atom, which is characteristic of a chemical element and determines its place in the periodic table.
atomic number, the number of a chemical element in the periodic system, whereby the elements are arranged in order of increasing number of protons in the nucleus. Accordingly, the number of protons, which is always equal to the number of electrons in the neutral atom, is also the atomic number. An atom of iron has 26 protons in its nucleus; therefore the atomic number of iron is 26.

An isomer is a compound which has the same atoms as another, but the spatial arrangement of the atoms is different. If we wish to have an ethyl, or two carbon, side chain, then the main chain may be five carbon atoms long. This compound then becomes:
3-ethylpentane; where the parent chain is pentane and the ethyl group is attached to the third carbon from the start of the parent chain.
