Answer: The thermocline begins at 100 meters of depth.
Step-to-step explanation:-
Thermocline is a transition oceanic water layer between deep and surface water in which water temperature decreases rapidly with increasing depth.
From the given graph it cam be seen that at 100 meters the thermoline begins such that the temperature drops from to .
Hence, the thermocline begins at 100 meters of depth.
Answer:
D. 150 m
Explanation:

c. CO2 2H2O
TRUE
FALSE
(3) Two electrons are transferred.
(4) Four electrons are transferred.
Answer:The correct answer is option (2).
Explanation:
A covalent bond is defined as sharing of the electrons between two atoms with less or zero difference in their electronegativites.
A multiple covalent bonds are those bond where more than one bond is present. Like double or triple bonds.
In double covalent bonds there are 4 electrons are shared.
in triple covalent bonds there are 6 electrons are shared.
Single covalent bond is formed by sharing of two electrons while multiple covalent bond is formed when 4 electrons are shared, thus the correct option is 2.
Covalent bond is defined as a type of bond which is formed by the mutual sharing of electrons to form electron pairs between the two atoms.These electron pairs are called as bonding pairs or shared pair of electrons.
Due to the sharing of valence electrons , the atoms are able to achieve a stable electronic configuration . Covalent bonding involves many types of interactions like σ bonding,π bonding ,metal-to-metal bonding ,etc.
Single covalent bond is formed when 2 electrons are shared while multiple covalent bond is formed when 4 electrons are shared, thus the correct option is 2.

Answer:
We can assume that allforceactingontheboxarebalancedinalldirections.
It is the type of cell used in electroplating
It uses an electric current to make a nonspontaneous reaction go.
All of the above
18. The products formed in the net reaction of the electrolysis of water are ____.
aqueous hydrogen ion and hydroxyl ion
hydrogen gas and oxygen gas
liquid hydrogen and oxygen gas
liquid oxygen and hydrogen gas
19. What occurs in electroplating?
decomposition of a metal layer
decomposition of a salt layer
deposition of a metal layer on a material
deposition of a salt layer on a metal
An electrolytic cell uses an electric current to make a nonspontaneous reaction go and is used in electroplating. The products formed in the electrolysis of water are hydrogen gas and oxygen gas. Electroplating involves the deposition of a metal layer on a material.
An electrolytic cell is a type of cell that uses an electric current to make a nonspontaneous reaction go. This means it can drive a chemical reaction in a direction that does not occur naturally. Electrolytic cells are commonly used in electroplating, where a metal layer is deposited onto a material. Therefore, all of the given options in question 17 are true about an electrolytic cell. For question 18, the products formed in the net reaction of the electrolysis of water are hydrogen gas and oxygen gas. Electrolysis of water involves the decomposition of water into its elemental components. In electroplating, the process involves the deposition of a metal layer on a material. This is achieved by passing an electric current through a solution containing metal ions, causing the metal ions to be reduced and deposit onto the material's surface.
