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:
Based on giveninformation, the compound is a Poly Unsaturated 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 CH₃(CH₂)₁₀COOH

Myristic Acid CH₃(CH₂)₁₂COOH

Palmitic Acid 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:
Linoleic acid

Vaccenic acid

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 Hexacosa-3,9-dienoic acid with following structure.

An aqueous solution of potassium carbonate combine with a solution of calcium nitrate. What are the total and net ionic equation

romanna [79]

K_2CO_3(aq)+Ca(NO_3)_2(aq)→ ?
If we break these two reactants up into their respective ions, we get...
K^+ + CO^2_3 + Ca^2+ + NO_−3
If we combine the anion of one reactant with the cation of the other and vice-versa, we get...
CaCO_3 + KNO_3

Now we need to ask ourselves if either of these is soluble in water. Based on solubility rules, we know that all nitrates are soluble, so the potassium nitrate is. Alternatively, we know that all carbonates are insoluble except those of sodium, potassium, and ammonium; therefore, this calcium carbonate is insoluble. This is good. It means we have a driving force for the reaction! That driving force is that a precipitate will form. In such a case, a precipitation reaction will occur, and the total equation will be...
K_2CO_3(aq) + Ca(NO_3)_2(aq) → CaCO_3(s) + 2KNO_3(aq)

To determine the net ionic equation, we need to remove all ions that appear on both sides of the equation in aqueous solution -- these ions are called spectator ions, and do not actually undergo any chemical reaction. To determine the net ionic equation, let's first rewrite the equation in terms of ions...
2K^+(aq) + CO_3^{2-}(aq) + Ca^{2+}(aq) + 2NO_3^{-}(aq) → Ca^{2+}(s) + CO_3^{2-}(s) + 2K^+(aq) + 2NO_3^-(aq)

The species that appear in aqueous solution on both sides of the equation (spectator ions) are... 
2K^+,NO_3^-
If we remove these spectator ions from the total equation, we will get the net ionic equation...
CO_3^{2-}(aq) + Ca^{2+}(aq) → CaCO_3(s)
