Answer:
The answer to your question is 27.3 %
Explanation:
Percent by mass = ?
Process
1.- Calculate the atomic mass of carbon using the periodic table
Atomic mass = 12g
2.- Calculate the molecular mass of CO₂.
Carbon = 12
Oxygen = 16 x 2 = 32
Total = 12 + 32 = 44g
3.- Calculate the percent by mass of carbon using proportions
44g -------------------- 100%
12 g ------------------- x
x = (12 x 100) / 44
x = 1200 / 44
x = 27.3 %

Answer:
To study the organism.
Explanation:
When paleontologists find only partial remains of some organism so they study it in order to find the characteristic of the organism and find out the history of earth. paleontologists are the scientists who study fossils of plants and animals to study the history of earth so we can say that paleontologists study the partial remains in order to study the history of earth.
The amine here is the easiest to spot since there’s only one structure that has a nitrogen atom, which would be the first (the first structure is a primary amine).
The distinguishing functional group of an alcohol is the hydroxy group (—OH). Both the second and third structures have an —OH group, but the —OH in the third structure is part of a carboxyl group (—COOH or —C(=O)OH). A carboxyl group takes priority over hydroxy group. Thus, the second structure would be an alcohol and the third structure would be a carboxylic acid.
That leaves us with the fourth structure, a hydrocarbon with a halogen substitutent, or, aptly named, a halocarbon.
