Which formed first: hydrogen nuclei or hydrogen atoms?
Mama L [17]
This sounds very much like a chicken-egg problem.

The first thing that formed must be hydrogen nuclei. The only other alternative is that the atom was created instantly, and the nuclei sprang forth at the same time as the atom, meaning that neither was technically first. The logic is that an atom can’t form without a nucleus, but it theoretically could be created instantly.

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.
