Answer:
The most common position for an double bond in an unsaturated fatty acid is delta 9 (Δ⁹)
Explanation:
Unsaturated fatty acids are carboxylic acids which contains one or more double bonds. The chain length as well as the number of double bonds is written separated by a colon. The positions of the double bonds are specified starting from the carboxyl carbon, numbered as 1, by superscript numbers following a delta (Δ). For example, an 18-carbon fatty acid containing a single double bond between carbon number 9 and 10 is written as 18:1(Δ⁹).
In most monounsaturated fatty acids, the double bond is between C-9 and C-10 (Δ⁹), and the other double bonds of polyunsaturated fatty acids are generally Δ¹² and Δ¹⁵. This positioning is due to the nature of the biosynthesis of fatty acids. In the mammalian hepatocytes, double bonds are introduced easily into fatty acids at the Δ⁹ position, but cannot introduce additional double bonds between C-10 and the methyl-terminal end. However, plants are able to introduce these additional double bonds at the Δ¹² and Δ¹⁵ positions.

I just learned all this in chemistry too lol
got 100 on the test last week so its good
Answer:
59.76 grams of Li₂O
Explanation:
To solve this problem we will first calculate the moles of Li₂O. One mole of given substance always contains 6.022 × 10²³ particles which can be atoms, ions, molecules or formula units. This number is also called as Avogadro's Number.
The relation between Moles, Number of Particles and Avogadro's Number is given as,
Number of Moles = Number of Particles ÷ 6.022 × 10²³
Putting values,
Number of Moles = 1.204 × 10²⁴ Particles ÷ 6.022 × 10²³
Number of Moles = 2.0 Moles
Secondly, we will convert calculated moles to mass using following relationship.
Moles = Mass / M.Mass
Or,
Mass = Moles × M.Mass
Putting values,
Mass = 2.0 mol × 29.88 g/mol
Mass = 59.76 grams of Li₂O
In ions atoms lose and gain electrons
