The gas goes through a chemical reaction where the products have fewer gas particles than reactants. Since the number of particles directly relates to pressure, the pressure dropped.
PV = nRT is the ideal gas law.
Pressure also reduced as drug amount did.
PV = nRT is the equation for an ideal gas. In this equation, P stands for the ideal gas's pressure, V for the ideal gas' volume, n for the total amount of the ideal gas expressed in moles, R for the universal gas constant, and T for temperature.
PV = nRT
The macroscopic characteristics of ideal gases are related by the ideal gas law (PV = nRT). A gas is considered to be perfect if its particles (a) do not interact with one another and (b) occupy no space (have no volume).

Review to make them an isotonic solution a hypotonic solution such as tap water a hypertonic solution made with distilled water and a tablespoon of salt a hypertonic solution such as distilled wate
If you are going to bake potatoes, and your potatoes are soft and dehydrated, they can be soaked in hypotonic solution in a more firm before baking.
Before baking potatoes that are soft and dehydrated, it is important to give them a good soaking to make them firmer.
For this, a hypotonic solution such as salt water is preferred. Start by filling a large bowl with cold water and adding some salt. The salt will help to draw out moisture from the potatoes, making them firmer and more suitable for baking. Submerge the potatoes in the water and let them soak for at least 30 minutes.
Drain the water and pat the potatoes dry with a paper towel. This will remove any excess moisture and help them to crisp up when baking. You can then season the potatoes as desired and bake them as normal. The soaking process helps to rehydrate the potatoes, making them firmer and more suitable for baking.
The salt also helps to draw out moisture, so that when the potatoes are baked, they will be crisp on the outside and fluffy on the inside. The soaking process is an important step in preparing potatoes for baking, as it helps to make them firmer and more suitable for baking.

What is enantiomeric compounds?
An enantiomer is one of two stereoisomers that cannot be superposed onto its own mirror image. It is also known as an optical isomer, antipode, or optical antipode. Enantiomers are similar to one's right and left hands in that they cannot be superimposed on one another when staring at the same face.
Because the effects of the two enantiomers cancel each other out molecule for molecule, a 50:50 mixture of the two enantiomers will not rotate plane polarised light. Racemate or racemic mixture is the term used to describe this kind of composition. A racemic combination has no defined rotation.
Enantiomeric excess is a technique for determining how much of the primary enantiomer is present in the mixture that is above 50%. It is set to 100% to represent the pure enantiomer and 0% to represent a racemic mixture. You may figure it out by multiplying the rotation of the combination as seen by the rotation of the pure enantiomer.

write short note about acid nomenclature
Acids
There are various definitions for an acid. The simplest description of an acid is a chemical molecule with one or more hydrogen atoms that, when dissolved in water, gives forth hydronium ions (H3O+).
Because acids are molecular, they do not assume the expanded three-dimensional structures of ionic substances like NaCl and remain single molecules in their pure form. However, when these molecules are dissolved in water, a positively charged anion and a hydronium ion are produced as a result of the chemical connection between the hydrogen atom and the remainder of the molecule breaking. An equation involving chemicals can represent this:
HCl+H2O→H3O++Cl−
In an inorganic acid's formula, the H of the acid is written first. After the acid dissolves, the anion is all that is left of the acid (apart from the H). Although a significant class of chemicals, organic acids are not covered in this article.
Acid Names
Since all acids contain hydrogen, an acid's name is determined by the anion that it is associated with. These anions come in monatomic and polyatomic forms.
Binary acid names (in aqueous form)
An acid that contains hydrogen and another element is referred to as a binary acid. The majority of binary acids have a halogen in them. The prefix hydro- is used to start an acid name, which is then followed by the base name of the anion and the suffix -ic.
Oxyacids name
An oxyacid is an acid made up of three elements: hydrogen, oxygen, and another one. Typically, the third element is a nonmetal.
a) Oxyanions with the -ite end.
The anion's root is followed by the suffix -ous to form the name of the acid. No prefix is present.
b)Oxyanions that end in -ate.
The anion's root and the suffix -ic are used to identify the acid. No prefix is present.
In conclusion
Acids are molecular substances that discharge hydrogen ions.
The two elements hydrogen and the other make up a binary acid.
Hydrogen, oxygen, and another element are all present in oxyacids.
The anion that is bound to the hydrogen provides the basis for the acid's name.
