Answer:
Fatty acids have a carboxyl group at one end of a hydrocarbon molecule.
<u>The carbon atoms in saturated fatty acids are linked entirely by single C-C bonds.</u>
Unsaturated fatty acids contain one or more double bonds.
<u>Double bonds cause molecules to bend, and they can pack less tightly.</u>
Isotopes of an element are defined has that has same atomic number but different mass number mean they have different number of neutrons
so the statement that best describe a similarity is
<span> same atomic number; different mass number
</span>so correct option is C
hope it helps
The two are potassium and rubidium. Why? Na is an alkali metal. As you go down the metals become more reactive.
Calcium has 20 protons. Why? The atomic # is 20 (the one at the top).
It has 20 neutrons. Why? The atomic mass (the number on the bottom) is ~40, ignoring electron mass. 40- 20 protons = 20 neutrons.
It has 20 electrons.
Why? The # of protons and electrons is the same. Ions aren't on the periodic table.

Maybe b and c ? It’s makes sense to wear protective clothing and staying indoors
