Because their ions are free to move from place to place. Ionic compounds cannot conduct electricity when solid, as their ions are held in fixed positions and cannot move.
Structure 1: 2-Butyne
Parent chain contains 4 carbons and a triple bond. So, the parent name is Butyne. Position of triple bond is written 2, as triple bond starts at carbon 2.
Structure 2: <em>cis</em>-2-Pentene
Parent chain contains 5 carbons and a double bond. So, the parent name is Pentene. Position of double bond is written 2, as double bond starts at carbon 2. As both substituents are on same side of double bond, so cis depicts the stereo.
Structure 3: <em>trans</em>-3-Decene
Parent chain contains 10 carbons and a double bond. So, the parent name is Decene. Position of double bond is written 3, as double bond starts at carbon 3. As both substituents are on opposite side of double bond, so trans depicts the stereo.
Structure 3: 1-Hexyne
Parent chain contains 6 carbons and a triple bond. So, the parent name is Hexyne. Position of triple bond is written 1, as triple bond starts at carbon 1.
Nonessential amino acids can be made by the body, while essential amino acids cannot be made by the body so you must get them from your diet.
Nonessential acids : glutamine, proline, glycine etc
Essential acids: lysine, leucine etc.
<span>Get into moles first. .0590 grams over 540.8 grams per mole = 1.09 x l0^-4 moles
Sr3(As04)2 = 3 Sr++(aq) plus 2 As04^-3(aq)
Ksp = (Sr++)^3(As04^-3)^2
(Sr++) = 3 X l.09 x l0^-4 = 3.27 x l0^-4
(As04^-3) = 2 x l.09 x l0^-4 = 2.18 x l0^-4
<span>Ksp = (3.27 x l0^-4)^3 (2.18 x l0^-4)^2 which equals 1.66 x 10^-18th
I hope my answer has come to your help. Thank you for posting your question here in Brainly.</span></span>
Calories is a unit of energy, so we need to calculate the energy or heat absorbed or released by the system. We use the equation:
U = mCpΔT
where:
m = mass of material
Cp = specific heat capacity of material
ΔT = (Tf - Ti) = temperature change
First, you must look for the specific heat capacity of copper. You can use any chemistry or engineering book or website. According to Engineering Toolbox, the specific heat capacity of copper is 0.09 cal/(g-°C).
U = 200(0.09)(33-28) = 90 calories
Since the value is positive, energy is absorbed.
