Chemistry

Yes. Fish are made up of complex chemistry, just like all living organisms.

Their bodies contain:

Water — makes up much of a fish's body.

Proteins — form muscles, enzymes, hormones, and other structures.

Lipids (fats) — provide energy and form cell membranes.

Carbohydrates — used mainly for energy storage and metabolism.

DNA and RNA — carry and use genetic information.

Minerals and ions — such as calcium, sodium, potassium, and phosphorus, which help regulate nerves, muscles, bones, and fluid balance.

Pigments and other molecules — contribute to coloration, vision, and protection.

Fish also carry out thousands of chemical reactions every second, including digestion, cellular respiration, growth, and maintaining the balance of salts and water in their bodies.

So, although a fish may look relatively simple externally, its body is a highly complex chemical system.

Weigh a hydrated sample.

Drive off the water.

Re-weigh the de-hydrated sample.

The difference in mass is the water drive off.

From which tou can calculate the moles of water driven off. and thereby the amount of water of hydration.

Probably Francium Fluoride ( FrF).

However, you will NOT find this substance in an open lab. because Francium (Fr) is radio-active.

The first ionisation energy of francium is very low. and the 1st electron affinity of fluorine is very high . So they will ionically bond very readily.

RO water and Aquaguard water aren’t really two different types of water. RO (reverse osmosis) is a purification technology that uses a membrane to reduce dissolved salts, minerals, and certain contaminants from water.

Aquaguard is a brand that makes water purifiers using different technologies, including RO, UV, and filtration. So, an Aquaguard purifier may produce RO water if it has an RO system. The actual water quality depends on the purifier’s technology and the quality of the incoming water.

The Electrons and the Protons.

The chemical formula for carbon monoxide is CO. It consists of one carbon atom bonded to one oxygen atom by a covalent bond. Carbon monoxide is a colorless, odorless gas that is toxic to humans when inhaled in high concentrations.

Carbon monoxide is ' CO'.

Compare to Carbon dioxide. , which is ' CO2 '.

From the Latin roots ; ' Mono - '1' , and ' Di - '2'.

An electrolyte is any substance that dissolves in water, and allows electrocity to pass.

Common electrolytes are sodium chloride, and sodium carbonate. They form the ions Na^(+) , Cl^(-) and CO3^(2-) on dissolution in water. These ions are free to move, hence electrical flow.

NB THere are many more electrolyyes.

An atom of 18 protons is an atom of Argon, which is a Noble/Inert Gas.

Consequently being an inert gas it does NOT gain extra electrons.

So an atom of Argon does NOT have 22 electrons. It only has 18 electrons, . in order to remain neutrally charged. It does NOT form an ANION .

The number of protons indicates the element(name).

The number of neutrons indicates the isotopic mass.

The phase changes of matter are melting (solid to liquid), freezing (liquid to solid), vaporization (liquid to gas), condensation (gas to liquid), sublimation (solid to gas), and deposition (gas to solid). These transitions occur due to changes in temperature and pressure.

A pungent smell is a strong, sharp or slightly irritating odour that you notice easily. Mustard is a common example.

In mustard seeds, sinigrin and the enzyme myrosinase naturally occur. When the seeds are crushed and moisture is present, they can contribute to the formation of allyl isothiocyanate (AITC), which is a major contributor to mustard’s characteristic pungency and sharp aroma.

The important point is that strong smell or pungency does not necessarily mean better quality or purity. Its intensity can vary with the mustard variety, seed condition and processing method.

This is something I have also observed while working with mustard oil at Pure Tatva. A milder-smelling mustard oil is not automatically impure or adulterated.

I’m Ravi Pratap Rana, Founder of Pure Tatva, with 19 years of experience in the Pharmaceutical Industry, including experience in production, formulation development and operational excellence.

So, simply put: pungent smell means a strong, sharp odour—and in mustard, it is largely associated with naturally formed compounds such as AITC.

Water is made up of two hydrogen atoms and one oxygen atom. the formula for water is H2O. the two elements the make up water are hydrogen and oxygen. the two elements the make up water are hydrogen and oxygen.

Elements in Group 1 of the periodic table are called alkali metals. This group includes elements such as lithium, sodium, and potassium. They are highly reactive metals that readily form ionic compounds.

These chemical elements are called transition metals.

If you put a bottle sterilizer in the microwave without water the microwave will likely overheat and may be damaged. Additionally the bottle sterilizer itself may melt warp or be damaged in other ways. It is important to always use water with the bottle sterilizer when microwaving it. Here are some steps to follow when microwaving a bottle sterilizer:

• Fill the bottle sterilizer with the recommended amount of water.
• Place the bottle sterilizer in the microwave.
• Set the microwave to the recommended time and power level.
• Allow the sterilizer to cool once the cycle is complete.

Failing to follow these steps can lead to damage to your microwave and bottle sterilizer so it is important to proceed with caution when microwaving a bottle sterilizer.

Aluminum has 13 electrons arranged in 3 energy levels. The first two levels are filled, each with 2 and 8 electrons, respectively, and the third level has 3 electrons. Since aluminum has equal numbers of protons and electrons (13 each), the positive charge of the protons is balanced by the negative charge of the electrons, resulting in no overall electrical charge on the aluminum atom.

The overall charge on an atom of aluminium is 'ZERO' . The number of protons equals the number of electrons.

An atom with three extra electrons is NO longer an atom but an ANION.

e.g. N2 + 6e^(-) = 2N^(3-)

A moleculae of nitrogen contains two atoms. Six electrons combine to form two ANIONS (N^(3-))

If there were extra electrons in an atom, it would no longer be an atom , but an ANION.

e,g,

Cl2(g) + 2e^(-) = 2Cl^(-)

A moleculae of chlorine has combined with two electrons (e) to form two chloride anion (Cl^(-)).

The each chlorine atoms has gained an extra electron .

The real challenge of flame-retardant treatment for CVC fabric lies in the fact that cotton and polyester behave completely differently when exposed to heat. Cotton tends to dehydrate and form a char layer, while polyester softens, melts, and can continue to contribute to burning. When these two fibers are blended, the char formed by cotton can act as a supporting structure that holds the molten polyester close to the heat source, creating what is often described as a “scaffolding effect.” As a result, a flame-retardant finish that works well on cotton alone may not perform effectively on CVC fabric. The problem is not simply the cotton content or the amount of flame retardant applied—it is the fundamentally different combustion behavior of the two fibers.

That is why achieving reliable flame resistance in CVC requires more than simply increasing the dosage of a flame-retardant chemical. The treatment must work effectively across both fiber components while also preventing molten polyester from reinforcing the combustion process. Excessive chemical loading or heavy surface coatings may improve initial flame resistance, but they can also compromise softness, breathability, appearance, and durability after washing. The key to successful CVC flame-retardant treatment is therefore a carefully designed system that addresses the combustion behavior of cotton and polyester together, rather than treating the fabric as if it were a single-fiber material.

The symbol used in a chemical equation for an aqueous solution is (aq) to indicate that a substance is dissolved in water. This symbol is placed next to the chemical formula of the dissolved substance.

There are no elemental symbols using a single letter 'L'.

The element ' Lanthanum ' is ' La'.

The element wi a name beginning with 'L' is ' Lead' (Pb). 'Pb' is the symbol for 'lead;, and comes from the Latin name for lead, which is 'plumbum'.
