First, it combines with carbon dioxide in the soil to form a weak acid called carbonic acid. ... Carbonic acid slowly dissolves away minerals in rock, especially the carbonate minerals that make up limestone and marble. The weak acid decomposes the insoluble rock into watersoluble products that move into the groundwater.
Answer:
B. CO + H₂O → H₂ + CO₂
Explanation:
Redox reaction -
It is the type of reaction , where the process of oxidation and reduction takes place simultaneously , is known as a redox reaction .
Oxidation refers to the addition of oxygen atom or the removal of hydrogen atom .
And ,
Reduction refers to the addition of hydrogen atom or the removal of the oxygen atom .
From the options given in the question , the only reaction , which have both the process of oxidation as well as reduction , is -
CO + H₂O → H₂ + CO₂
In the above reaction ,
Oxidation process - CO → CO₂ ,
The addition of oxygen atom .
Reduction process - H₂O → H₂ ,
The removal of oxygen atom .
Answer:
the energy of matter implies the motion of masses and the energy of the wave has no moving masses
The energy of the particles (matter) is the ability to do some work, therefore the energy can be of motion in the form of kinetic energy or in a configuration of the system called potential energy, the sum of these two energy is constant .
The wave is formed by a disturbance of the medium by matter, therefore for the formation of the wave matter supply energy, for example: in the form of movement, in the form of fluctuation of electric or magnetic field, etc.
The waves after being formed can move away from the matter that formed them, transporting the energy that alternately has kinetic and potential energy, but the total energy is constant.
Therefore the energy in matter is due to the movement of the same and the energy in the wave does not require the movement of matter, so it is a more efficient way of doing work.
In conclusion, the energy of matter implies the movement of masses and the energy of the wave has no moving masses.
Hi there!
Although there are only 20 amino acids, these amino acids can combine into an innumerable amount of combinations to form different and unique proteins.
In case that doesn't make sense to you, I'll provide you with an analogy. You could be provided with 20 different LEGO bricks to work with. While there may only be 20 bricks, these bricks can combine into a vast amount of different formations, structures, etc. Amino Acids work in the same way.
D= mass/volume so it's 100/68 which equals 1.47cm3
