Is mercury good in making battery

Chemistry
2 answers:
mars1129 [50]3 years ago
7 0

Answer:

No, Mercury can actually cause poisoning. That is why other metals, such as Alkaline metals, are used in making batteries

Likurg_2 [28]3 years ago
3 0

Answer:

Mercury can be found in most common household batteries but will most likely be discontinued in the future.

Explanation:

Zinc air, alkaline, and silver oxide button cell all include mercury but only in SMALL amounts. Chances of this mercury leaking are very unlikely and does not pose a large danger to people. In present day, most batteries are turning away from using mercury so its most likely mercury batteries will not be found in the future.

The role of pigments both in capturing light energy and in converting it to the chemical energy of ATP and NADPH.
Aleonysh [2.5K]

Answer:

The explanation of the processes in which pigments are involved (capturing light and forming ATP and NADPH) is given in the following paragraphs)

Explanation:

Pigments are molecules with the capacity of absorbing light. Each pigment captures light of a specific wavelength. Plants contain different types of pigments like chlorophylls, xanthophylls, carotenoids, and others.

Chloroplasts (organelles present in cells of plants), contain pigmants that absorb solar radiation, triggering a series of reactions collectively known as photosynthesis. When light incides on a pigment, an electron of this molecules is excitated, goes into another level of energy and starts to pass through a series of carrier molecules to finally to a final aceptor of electrons. During this transport, part of the energy contained in the electron is used to generates a hydrogen gradient that provides energy. As a result of these processes, a molecule that is called  NADP+ accepts two electrons and an hydrogen to form NADPH, while another molecule known as ADP captures  an atom of phosphorous and gives rise to ATP (through the action of a protein called ATP sintase)..

Which metal in Period 5 is very reactive and has two valence electrons in each atom?
Romashka-Z-Leto [24]
The answer is Strontium(Sr). The reactive increase from right to left. And this element has two valence electrons. So Rb is not correct. Then the very reactive metal is Sr.

The genetic material of all organisms;made up of two twisted strands in a double helix
viva [34]
Hello!

The genetic material of all organisms which is made up of two twisted strands in a double helix is called DNA (DeoxyriboNucleic Acid)

DNA 
is the basis of all genetic information. It contains all instructions for the development and functioning of all living organisms and some viruses. The main function of DNA is the long-term storage of information to build other cell components like Proteins and RNA. It is composed of two strands with 4 possible bases which are Adenine (A), Thymine (T), Cytosine (C) and Guanine (G).

The equilibrium for the reaction between (ch3)2nh a weak base
nadezda [96]

The equilibrium for the dissolution of the weak base is ;(CH3)2NH(aq) + H2O(l) ⇄ (CH3)2NH3^+(aq) + OH^-(aq)

<h3>What is a weak base?</h3>

A weak base is one that does not ionize completely in solution. As such, a weak base will have a very low base dissociation constant Kb reflecting its minimal dissociation in solution.

The question is incomplete hence we are are unable to work out the equilibrium but in solution it will look like this;

(CH3)2NH(aq) + H2O(l) ⇄ (CH3)2NH3^+(aq) + OH^-(aq)
