Chlorophyll, it is chlorophyll
When:
Fe(OH)3 ↔
Fe3+ + 3OH-so, each 1 mol Fe3+ → 3 mol OH-
and when [OH]
= 1.2 x 10^-5∴ [Fe3+] = (1.2 x 10^-5) / 3
= 4 x 10^-6when
Keq = [Fe3+][OH]^3 = (4 x 10^-6) (1.2 x 10^-5)^3
∴Keq = 6.9 x 10^-21
Answer:
Buoyancy.
Explanation:
Buoyancy is a force created by the water that is displaced by an object. It is directly proportional to the amount of water that is being displaced by an object.
Hence, the greater the amount of water an object displaces; the greater is the force of buoyancy pushing the object up.
The buoyancy of an object is given by the formula;
Where;
Fb = buoyant force of a liquid acting on an object.
g = acceleration due to gravity.
p = density of the liquid.
v = volume of the liquid displaced.
h = height of liquid (water) displaced by an object.
A = surface area of the floating object.
<em>The unit of measurement for the buoyancy of an object is Newton (N).</em>
If you made the sugar and corn syrup solutions you heated, the sugar made the solutions' boiling points higher than that of pure liquid water.
Answer:
The answer to your question is: The first option.
Explanation:
Outer electron shell because these electrons can be readily exchanged with adjacent atoms As is mentioned in the statement, these electrons can be exchanged easily with adjacent atoms, so this is the right answer.
Innermost electron shell because the electrons can be transferred to the nucleus. Innermost electrons can not react as easily as the outermost, because they are protected by the outermost shells. This answer in not correct.
Middle electron shell because they are intermediate in distance between the nucleus and the adjacent atom that bonds with the atom. In order that an electron can react, it must be located in the outermost shell, it is not an advantage to be in the middle shells. This option is incorrect.
Any electron can exchange with adjacent atoms to form a bond; there is no preference. Not any electron can react with another element, only the electrons in the outermost shell can react, this option is incorrect.
