A scientist has isolated a fatty acid that has 26 carbons. most of the carbon atoms in the fatty acid chain are connected by sin
Shtirlitz [24]
Answer:
            <span>Based on giveninformation, the compound is a <u>Poly Unsaturated</u> fatty acid.

Explanation:
                   Fatty acids are carboxylic acids with -COOH functional group and a chain of hydrocarbons.

Fatty Acids are classified as,

i) Saturated Fatty Acids:
                                      Those Fatty Acids in which there is no double bond between the carbon chain are called as saturated fatty acids. 

Examples:
                 Lauric Acid           </span>CH₃(CH₂)₁₀COOH<span>

                 Myristic Acid         </span>CH₃(CH₂)₁₂COOH<span>

                 Palmitic Acid         </span>CH₃(CH₂)₁₄COOH

ii) Unsaturated Fatty Acids:
                                      Those Fatty Acids in which contain a single double bond (mono-unsaturated) or more than one double bond (poly-unsaturated) d between the carbon atoms in a chain are called as unsaturated fatty acids. 

Examples:
                 <span>Linoleic acid
</span>
                 <span>Vaccenic acid

                 </span><span>Palmitoleic acid

The saturated fatty acid containing 26 carbon atoms is called as Cerotic acid. While cerotic acid containing a double bond at position 3 and 9 has a IUPAC name H</span>exacosa-3,9-dienoic acid with following structure.

In the reaction MgCl2 + 2KOH Mg(OH)2+ 2KCI, if 3 moles MgCh are added to 4 moles KOH, what determines how much Mg(OH)2 is made?
gulaghasi [49]

Answer:-

KOH determines how much Mg(OH)2 is made.

2 mol of Mg(OH)2 formed

Explanation:-

The balanced equation is

MgCl2 + 2KOH --> Mg(OH)2+ 2KCI,

From seeing the coefficients we notice

2 mol of KOH reacts with 1 mol of MgCl2

4 mol of KOH reacts with 1 x 4 / 2 = 2 mol of MgCl2

3 moles of MgCl2 was added but only 2 mol react.

So we see there is excess MgCl2 .

Hence KOH is the limiting reactant.

So KOH determines how much Mg(OH)2 is made.

We see from the balanced chemical equation,

2 mol of KOH gives 1 mol of Mg(OH)2.

4 mol of KOH will give 1 x 4 /2 = 2 mol of Mg(OH)2.
