Will an egg rot if you put it in vinegar?

Yes, when you place an egg in vinegar, a chemical reaction occurs that dissolves the eggshell, leaving behind the egg membrane. Over time, the egg may break down and turn mushy as the vinegar breaks down the proteins in the egg.

What is the name of CH3COCH3?

The modern IUPAC name is ' propanone' , but archaically, and commonly known as ' acetone'.

What is the chemical formula for ethyl alcohol?

Ethyl Alcohol is the archaic/everyday name for 'alcohol;, asfound in beers, wines and spirits.

Its modern IUPAC name is 'Ethanol'.

Its formula is usually shown in 'structural form' as ; CH3-CH2-O-H'

However, this can be reduced to ' C2H6O '. Since there are other organic substances with the formula ' C2H6O' it is better to show it in the structural form. e.g. CH3-O-CH3 ( diethyl ether).

Be it called ' alcohol/ethyl alcohol/ethanol it is still the same substance with the same structure.

The general alcohol functional group formula is shown as ' R-CH2OH'. 'R' being the rest of the molecule. , and the alcohol is ALWAYS shown as ' = CH2OH'. as standard IUPAC practice.

What is the rubidium reactivity?

how is the reactivity for ptassium

Do fish consist of complex chemistry?

According to the Book of Genesis 1: 20-23 in the Bible, great sea monsters and every living creature according to their kinds were created the fifth day of God's creation creation.

The fact that our planet Earth bears the unmistakable stamp of deliberate design according to their kinds, we are all aware that there is no design without a designer.

And even a simple fish body and design is highly complex in many ways. What of our far more intricate awesome varieties of creatures on earth. Something to think about.

Fish family has their varities. Dogs family has many varieties, but they always remain according to their kind. There is great variety in human family, but humans reproduce only ' after their kind and so forth...

The Book of Genesis chapter 1 in the Bible, contains all what each and everyone should be aware of.

God ended his creation in these words. Genesis 1: 31 reads."After that God saw everything he had made, and look ! it was very good.

Not only good,( but VERY GOOD ) We can only come to the same conclusion.

How do you calculate the percent water in a hydrate?

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.

Which bond has the most ionic character?

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.

What is difference between r-o water n aqua-guard water?

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.

What is CO formula?

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.

What is the chemical formula for the Carbon monoxide (covalent)?

Carbon monoxide is ' CO'.

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

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

What is Electrolyte's common name chemical name chemical formula?

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.

What is the chemical name of MgSO4.5H2O?

Calcium sulfate pentahydrate

If an atom has 18 protons 15 neutrons and 22 electrons what is the atoms electrical charge?

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.

What are the phase changes of matter?

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.

What is pungent smell?

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.

Elements that make up water?

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.

What are the elements in Group 1 of the periodic table called?

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.

What happens if you put bottle sterilizer in microwave without water?

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.

Why is there no overall electrical charge on an aluminium atom?

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.

What is aluminum overall charge of an atom?

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

What is the overall charge of an atom with 3 extra 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-))

What would happen if there were extra electrons in an atom?

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 .
