Endoplasmic reticulum.
I have biology this semester too :)
The two molecular characteristics of substances that typically form liquid cyrstals and there phases are long, cylindrical shape and between molecules & strong intermolecular forces exist
All these enables different application of liquid crystals

The elements whose electron configurations end with f electrons are in the Lanthanide and Actinide series: those long series at the bottom of the Periodic Table (see image).
The atoms are adding electrons into f orbitals, but the f electrons are not always the last electrons in the electron configuration.
For example, the electron configuration of Eu is [Xe]6s²4f⁷, but that of Gd
is [Xe] 6s²4f⁷5d.
I have blocked off in <em>red</em> all the <em>exceptions</em> like Gd.
The -COOH attached to the CH3 is the acid functional group.
<h3>What is a functional group?</h3>
The term functional group refers to the atom, group of atoms or bond which accounts for the chemical reactivity of a compound.
The acid functional group is known by the formula -COOH. In this case, we can see that the -COOH attached to the CH3 is the acid functional group.

Answer:
N₂O₅ + H₂O --> 2HNO₃
This reaction is a combination reaction
Explanation:
I find that making a table is an easy way to balance a table. The table would be something like this:
Reactants (left) Products (right)
N = 2 N = 1
O = 6 O = 3
H = 2 H = 1
The number next the symbol represents how many of atoms of that particular element are present.
The aim is to make the number of atoms of each element on the left side to be equal to the number of atoms of each element on the right side. As we can see, there are 1 more nitrogen than on the right, 3 more oxygen than on the right and 1 more hydrogen than on the left.
So to make the numbers of atoms of each element on right equal to the number of atoms of each element on the left, we have to add a number. This number CANNOT be a subscript number because that would change the reaction.
We can add a 2 in front of the product (this is because there are less atoms in the right side of the equation).
N₂O₅ + H₂O --> 2HNO₃
This means there are now two HNO₃ molecules so every atom in this molecule is basically multiplied by 2. So 1 nitrogen atom becomes two (1 × 2 = 2), 3 oxygen atoms become 6 (3 × 2 = 6) and 1 hydrogen atom becomes 2 (1 × 2 = 2). If we were to make a table again with the following equation - N₂O₅ + H₂O --> 2HNO₃, the table would be as so:
Reactants (left) Products (right)
N = 2 N = 2
O = 6 O = 6
H = 2 H = 2
Now the equation is balanced as we can see the number each type of atom is the same on the right and left side.
