Answer:
Structure 1- dodecanoic acid (lauric acid)
Structure 2- hexadecanoic acid (palmitic acid)
Structure 3- octadecanoic acid (stearatic acid)
Explanation:
Fatty acids are carboxylic acids having long aliphatic chain. The chain may be either saturated or unsaturated. There are many naturally occurring fatty acids having unbranched chain of an even number of carbon atoms.
Usually, the common name of the fatty acid is not related to its systematic name. Its systematic name is obtained by IUPAC nomenclature.
The images shown are the skeletal structures of lauric acid, palmitic acid and stearic acid. I have written the names of the acids because the question specifically mentions that the compounds are fatty acids and not their salts.
They have a chemical imbalance
Remember Anorexia is an eating disorder that causes people to obsess about weight and what they eat. It can get really serious.
Answer:
19.11g
Explanation:
mole = mass ÷ molar mass
mole = 2.61 ÷ 27
mole = 0.097mol
Number of atoms in 2.61g of Aluminum = 6.022 × 10^23 × 0.097
= 0.584 × 10^23
= 5.84 × 10^22atoms
To get the same number of atoms for Gold (Au), we multiply the atomic mass of Au by 0.097mol
Atomic mass of Au = 197g/mol
mass = mole × molar mass
mass = 0.097 × 197
mass = 19.109g
mass = 19.11g
Answer:
The answer is C) two covalent bonds between adjacent molecules.
Explanation:
The exact definition of a double bond is, "a chemical bond in which two pairs of electrons are shared between two atoms.
"<em> - Taken from Google Dictionary</em>

<em>The following information was taken from Wiki to help you understand the question, and so that no one thinks that I plagiarized: </em>
"A double bond in chemistry is a chemical bond between two chemical elements involving four bonding electrons instead of the usual two. The most common double bond occurs between two carbon atoms and can be found in alkenes. Many types of double bonds exist between two different elements."
I hope this helps!
