Answer is: A. 1.81 mol.
Balanced chemical reaction: FeCl₂ + 2KOH → Fe(OH)₂ + 2KCl.
n(FeCl₂) = 4.15 mol; amount of iron(II) chloride.
n(KOH) = 3.62 mol; amount of potassium hydroxide, limiting reactant.
From chemical reaction: n(KOH) : n(Fe(OH)₂) = 2 : 1.
n(Fe(OH)₂) = n(KOH) ÷ 2.
n(Fe(OH)₂) = 3.62 mol ÷ 2.
n(Fe(OH)₂) = 1.81 mol; amount of iron(II) hydroxide.
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.
The correct word to fill the blank in the sentence is "capillaries". The thinnest blood vessels in your body are the capillaries. These are the blood vessels that blood is able to transfer sugars and oxygen into the tissues.
If I am not mistaken, Seismic waves can penetrate the outer and inner core but can't travel through water very well.
