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
igomit [66]

Answer:

Polyunsaturated

Explanation:

A fatty acid is a compound that is derivative from a carboxylic acid. The chain of carbons can have since 4 carbons to more than 20 carbons. The bonds between carbons can be simple, which are called saturated bonds, or double, or triple, which is called unsaturated bonds.

When a fatty acid only has saturated bonds between carbons, it's called a saturated fatty acid. If there is only one unsaturated bond, it's called an unsaturated fatty acid, and if there are two or more unsaturated bonds, it's called polyunsaturated fatty acid.

How can you tell if an element is a metal or nonmetal?
Nataly_w [17]
If you look on the periodic table (especially one online) you can see that it is colour coded...so this might help...

If you look you can see a "staircase"..which consists of B, Si, Ge, As, Sb, Te, Po...If it is on the lefthand side of the staircase it is a metal (ie: Ni) or if it is on the righthand side it is a non metal. There is lots of images on google that can help point it out.
 
If you are talking in terms of properties you should look for (Metal) materials that are: 
<span>Lustrous
Hard.
High density  (heavy for their size)
High strength (resist being stretched)
High melting and boiling points.
<span>Good conductors of heat and electricity.

Non metals are/have:
</span></span><span>High ionization 
High electronegativities
Not malleable or ductile.
Little or no metallic luster.
Gain electrons easily.
<span>Dull, not metallic-shiny
</span></span>poor conductors of heat
and poor conductors of electricity 

Hope this helps!
