Answer:
The electrons of an atom are typically divided into two categories: valence and core electrons. Valence electrons occupy the outermost shell or highest energy level of an atom while core electrons are those occupying the innermost shell or lowest energy levels
Explanation:
i hope u get it :))
Your independent variable would be salt because it doesn't change the only thing that changes is the water.
Answer:
the resistance that one surface or object encounters when moving over another.
Explanation: :D
of the compound is found to be 5.04 ×

Solubility :Solubility can be define as the amount of a substance that dissolves or mixes in a given amount of solvent at specific conditions.
Solubility equilibrium
Ksp = ![[A^{+} ]^{a}](https://tex.z-dn.net/?f=%5BA%5E%7B%2B%7D%20%5D%5E%7Ba%7D)
![[B^{-} ]^{b}](https://tex.z-dn.net/?f=%5BB%5E%7B-%7D%20%5D%5E%7Bb%7D)
Ksp = solubility product constant
A+ = cation in an aquious solution
B- = anion in an aqueous solution
a, b = relative concentrations of a and b
Given,
Solubility = s = 3.60 × 
g/L
molar mass = 288 g/ mol
∴ s= 3.60 × g/L ÷ 288 g/ mol = 1.25 ×
mol/ L
Reaction:
MX3 ⇄ M + 3X
s 3s
=[ 
] [ 
![]^{3}](https://tex.z-dn.net/?f=%5D%5E%7B3%7D)
= solubility product
∴ =![[s]^{} [3s]^{3}](https://tex.z-dn.net/?f=%5Bs%5D%5E%7B%7D%20%5B3s%5D%5E%7B3%7D)
∴ = 3 
∴ = 3 × (3.60 × 
∴ = 503.8848 ×
= 5.04 ×

<span>Given in the question-
1 mole of cyclohexanol = > 1 mole of cyclohexene
Molar mass 100.16 g/mol
moles of cyclohexanol = .240 / 100.16= 0.002396 moles
Molar mass 82.143 g/mol
moles of cyclohexene formed @100 % yield = 0.002396
Molar mass 82.143 g/mol
mass of cyclohexene @ 100 % = .002396 x 82.143 = 0.197g
bur we have .138g
so % yield = .138 / .197 = 70.0 %
Ans- 70 percentage yield of cyclohexene.</span>
