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.
Answer:
A. 0.31 mol NaNO2
Explanation:
Buffer solutions are the solutions that resist changes in pH on addition of small amount of acid or base.
Buffer solutions usually contain the mixture of a weak acid and its salt, or a weak base and its salt.
Among the options listed in the question, only NaNO2 is the salt formed from the nitrous acid.
Here are two examples of strong nuclear force !
Protons and nucleons
I hope that's help !
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!
#2 It gives out more energy :)
