Answer:
A saturated fatty acid has the maximum possible number of hydrogen atoms attached to every carbon atom. It is therefore said to be “saturated” with hydrogen atoms. Some fatty acids are missing one pair of hydrogen atoms in the middle of the molecule.
D would be correct (i did this Assessment today)<span />
Answer:
At temperatures below −78 °C, carbon dioxide changes directly from a gas to a white solid called dry ice through a process called deposition.
Atoms are smaller than molecules, and they are also the smallest building blocks of matter. Atoms make up molecules when two or more atoms bond.
Answer: Option (c) is the correct answer.
Explanation:
The given reaction is as follows.

Number of atoms on reactant side are as follows.
Number of atoms on product side are as follows.
To balance the given equation, we multiply Fe by 2 and
by 3 on the reactant side. Therefore, the balanced chemical equation will be as follows.

Thus, the coefficient of
is 3.
