Battery or electrochemical cell
Explanation:
A battery is a power source that directs electrons from oxidation - reduction reactions to flow through a device to give electrical power.
- A battery is an electrochemical cell.
- Electrochemical cells are devices in which chemical reactions produce an electric current that is, chemical energy is turned into electrical energy.
- The reactions here are spontaneous redox reactions, hence electrons flows on its own in an external circuit.

Answer:
At physiological pH,the carboxylic acid group of an amino acid will be deprotonated while the amino group will be protonated,yielding the zwitter ion form.
Explanation:
Deprotonated means removal of protons in an acid base reaction and protonated means addition of protons in an acid base reaction.
Both protonated and de protonated reaction takes place in catalytic acid bade reaction by changing either it's mass or it's charge.
During formation of zwitter ion, the carboxylic acid will be deprotonated by donating the H+ ion while the amino acid is protonated by taking the H+ ion.

1. In 1687 following 18 months of intense and effectively nonstop work
2.Hooke
3.Halley
4. Halley urged newton to write Principia mathematica and when the Royal society declined to pay the cost of publishing Halley paid for it out of his own pocket
5.Through using a telescope Galileo Galilei was able to prove the theories of sciences Isaac newton
6. He believe that the speed of an object motion is proportional to the force being applied and inversely proportional to the density of the medium he reason that the object moving in a void would move in definitely fast and thus any and all objects
7. An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force

Answer:
The procedure you will use in this exercise exploits the difference in acidity and solubility just described.
(a) you will dissolve your unknown in ethyl acetate (an organic solvent). All of the possible compounds are soluble in ethyl acetate.
(b) you will extract with sodium bicarbonate to remove any carboxylic acid that is present.
(c) you will extract with sodium hydroxide to remove any phenol that is present.
(d) you will acidify both of the resulting aqueous solutions to cause any compounds that were extracted to precipitate.
To determine the name of an anion, you take the name of its element and replace the end with "ide".
<h3>What is an anion?</h3>
An anion in chemistry is a negatively charged ion.
Anions are usually formed when a non-metallic atom gains electron(s).
An anion is usually named by taking the elemental name, removing the ending, and adding “ide.
Examples of anions are as follows:
- fluoride (F-)
- Chloride (Cl-)
- Iodide (I-)
