they vary. it used to be meat, grain, bread, candy, beverages, donuts, and fruits/vegetables. now they added exercise in.

the dissociation of nickel hydroxide is follows:

[tex]ni(oh)_2 > ni^2^+ + 2 oh^-[/tex]

[tex]ksp for no(oh)2 = 5.5 * 10^-^1^6[/tex]

[tex]5.5 * 10^-^1^6 = s * (2 s)^2 = 4 s^3[/tex]

[tex]s^3 = 137.5 * 10^-^1^8[/tex]

[tex]s = 5.14 * 10^-^6 = [oh^-][/tex]

the concentration of hydroxide ion is

[tex]5.14 * 10^-^6 = [oh^-][/tex]

the equilibrium constant value of nickel hydroxide is = 6.1 * 10^-^1^6 and thus equilibrium equation can be written as:

[tex]k = [ ni^2^+] * [oh^-]^2[/tex]

[tex]6.1 * 10^-^1^6 = [ ni^2] * [5.14 * 10^-^6]^2[/tex]

[tex][ ni^2^+] = 0.23 * 10^-^4 mol /l[/tex]

thus, concentration of ni is 0.23 * 10^-^4 mol /l

Explanation:

The size of the orbital is determined by the principal quantum number (n), so the size of the orbital increases as this value increases. Therefore, an electron in a 1 orbital is closer to the nucleus than is an electron in a 2 orbital.

An atomic orbital can be thought of as the wave function of an electron in an atom. The Principal Quantum Number (n) is one of the quantum numbers that are required to describe the distribution of electrons in atoms. This quantum number has positive integral values such as 1, 2, 3 and so on. It also relates to the mean distance of the electron from the nucleus in a given orbital. The larger the quantum number, the greater the mean distance of an electron in that orbital from the nucleus, therefore the orbital will be larger.
