Answer:
The correct answer to the question is
D. 3 miles (4.5 kilometers)
Explanation:
The Carbonate compensation depth or (CCD) is the ocean depth at which calcite, (calcium carbonate) dissolves. At the CCD, the solvation rate of calcite is greater than the supply rate, such that all calcite are consumed.
The carbonate compensation depth varies in different parts of the ocean and can be reached at about 3 miles or 4.5 Kilometers.
Answer:
Alkane
Explanation:
Definition of Alkane "any of the series of saturated hydrocarbons including methane, ethane, propane, and higher members. (google dictionary)"
CH4 is methane.
Answer:
This is an example of a physical change because the ice cubes began to melt.
This is an example of a physical change because the ice cubes began to melt.
Explanation:
The above is the right answer to the question about the dissolution of the whole mixture mentioned in the excerpts above.
From Avogadro we obtained a physical constant of matter which is Avogadro's number, and from both scientists we understand that elementary gases such as hydrogen, nitrogen, and oxygen were composed of two atoms.
<h3>What is Avogadro's number?</h3>
Avogadro's number, or Avogadro's constant, is the number of particles found in one mole of a substance.
The Avogadro's number is given as 6.02 x 10²³.
Summary of Josef Loschmidt and Amedeo Avogadro Contribution to chemistry.
- Equal volumes of gas contain equal numbers of molecules,
- Elementary gases such as hydrogen, nitrogen, and oxygen were composed of two atoms.
Thus, from Avogadro we obtained a physical constant of matter which is Avogadro's number, and from both scientists we understand that elementary gases such as hydrogen, nitrogen, and oxygen were composed of two atoms.
