Answer:
Unicellular organisms are made up of only one cell that carries out all of the functions needed by the organism, while multicellular organisms use many different cells to function. ... Multicellular organisms are composed of more than one cell, with groups of cells differentiating to take on specialized functions.
Explanation:
does that make any sense???
Using the pH=-log[ hydrogen ions], assuming the pH of water is 7 then using the concept that kw=[ OH] [H+], then the [H+]= 10 power minus 7,since kw=10 to the power minus 14
Electrons are the only thing that can freely move from one object to another object. By rubbing the silk cloth on the glass, since the net charge becomes positive, that means that electrons were removed. So answer is : electrons removed.
The hydroxide ion concentration, [OH-] = 2.439 x 10⁻¹⁰
<h3>Further explanation</h3>
Equilibrium of water and the ions :
![\tt Kc=\dfrac{[H_3O^+][OH^-]}{H_2O}](https://tex.z-dn.net/?f=%5Ctt%20Kc%3D%5Cdfrac%7B%5BH_3O%5E%2B%5D%5BOH%5E-%5D%7D%7BH_2O%7D)
Kc[H₂O] is the ion equilibrium constant for water ⇒ Kw.
The product of the concentrations of these ions (H₃O⁺ and OH⁻)at equilibrium at 25°C is 1.0 x 10⁻¹⁴ M
[H₃O⁺] [OH⁻] = 1.0 x 10⁻¹⁴ M = Kw
The hydrogen ion concentration of [H⁺]=4.1 x 10⁻⁵ M, so the hydroxide ion concentration, [OH-] :
![\tt 4.1\times 10^{-5}\times [OH^-]=1.10^{-14}\\\\(OH^-]=\dfrac{1.10^{-14}}{4.1\times 10^{-5}}\\\\(OH^-]=2.439\times 10^{-10}](https://tex.z-dn.net/?f=%5Ctt%204.1%5Ctimes%2010%5E%7B-5%7D%5Ctimes%20%5BOH%5E-%5D%3D1.10%5E%7B-14%7D%5C%5C%5C%5C%28OH%5E-%5D%3D%5Cdfrac%7B1.10%5E%7B-14%7D%7D%7B4.1%5Ctimes%2010%5E%7B-5%7D%7D%5C%5C%5C%5C%28OH%5E-%5D%3D2.439%5Ctimes%2010%5E%7B-10%7D)
