How many moles are equivalent to 3.6x1024 formula units of MgBr2?
Using the Avogadro Number, of 6.022 x 10^(23) = one mole
Dividing
3.6000 x 10^(24) / 6.022 x 10^(23) = 5.97808.... moles.
What is the mass of 7 moles of MgBr2?
Using a copy of the Periodic Table, showing the Atomic Masses.
MgBr2
1 x Mg = 1 x 24 = 24
2 x Br = 2 x 80 = 160
24 + 160 = 184 the Mr ( Relative Molecular Mass) of tne molecule of MgBr2
Using the equation.
moles = mass(g) / Mr
Then mass(g = moles X Mt
So for '7' moles
mass(g) = 7 x 184 = 1288 g = 1.288 kg ( kilograms).
How many anions are there in MgBr2?
Two(2).
They are ' Br^(2) ' . The terminal '2' indicates that there are two anions.
NB
Collectively they are IONS .
Positively charged ions are ' CATIONS'. M^(n+)
Negatively charged ions are ' ANIONS'. X^(n-)
MgBr2 =
Mg^(2+) ' positively charged cation
2Br^(-) ' negatively charged anions.
For an ionic compound to be neutral , the charged MUST balance and be opposite. (+/-)
Hence MgBr2 = 2+ for magnesium and "2 x -1 = -2 ' for the two bromines.
Hence + 2 - 2 = 0
How many elements are in mgbr2?
In 'mgbr2' there are NO elements.
If you mean ' MgBr2'.
Then the elements are ;-
Magnesium (Mg)
Bromine (Br)
NB When writing chemical formulae, be it one or two letter symbol, the first letter is ALWAYS a CAPITAL letter. Hence my 'NO' for lower case letters.
MgBr2 is magnesium bromide. It is a combination of one cation ( atom) of magnesium and two anions( atoms of bromine.

How is coconut oil made and what is the process involved in its production?
Coconut oil can be produced in different ways depending on the type of oil being made. Broadly, the process involves preparing the coconut, controlling its moisture, extracting the oil and then filtering and storing the finished oil.
For virgin coconut oil, the quality of the coconut going into the process is particularly important.
At Pure Tatva, the process starts with sourcing coconuts directly from Tamil Nadu. We specifically look for good-quality, freshly procured coconuts and use sulphur-free, naturally sun-dried material, rather than relying on chemically dried coconut.
The coconuts are then inspected before processing. This is an important step for us because we don't want to simply buy ready-made sliced or dehydrated coconut and lose visibility of the raw material. We carry out the slicing in-house after the coconuts have passed our inspection.
The coconut is then further dehydrated in-house to control its moisture. Moisture is an important consideration during oil extraction because it can affect the processing behaviour and the stability of the finished oil.
Once the coconut has been properly prepared, we use our Zero Heat Extraction System to mechanically press the coconut and obtain the oil. The extracted oil is then filtered to remove suspended particles before it is packed.
The result is what we call Pure Tatva Virgin Juicy Coconut Oil.
One thing I would emphasise is that there isn't just one way of making coconut oil. Conventional refined coconut oil can involve considerably more processing after extraction, while virgin coconut oil generally involves less intensive processing and aims to retain more of the coconut's natural characteristics.
I also wouldn't judge a coconut oil simply by the words virgin, cold pressed or natural on the label. I would look at the quality and origin of the coconut, how it was dried, moisture control, extraction conditions, filtration and storage.
This is particularly important because the production story begins long before the oil reaches the bottle. If the raw material is already poorly handled, a good extraction machine cannot completely compensate for it.
I’m Ravi Pratap Rana, Founder of Pure Tatva, with 19 years of experience in the Pharmaceutical Industry, and my approach to oil processing has always been to pay attention to the complete process—from raw material selection to the final product.

So, in simple terms, the process is:
Quality coconut → inspection → in-house slicing → controlled dehydration → mechanical extraction → filtration → Virgin Coconut Oil.
CaSO3 is Calcium SULPHITE.
NB Do neither confuse with
CaSO4 which is Calcium SULPHATE.
Nor
CaS which is Calcium SULPHIDE.
They all have a different number or no oxygen's, and there is only ONE letter difference in the spelling. They are all different substances.
How do you determine the mole ratio in a chemical reaction?
You need to compose a BALANCED chemical reaction equation. The big numbers to the left of each compound are the mole ratios.
e.g.
2NaOH + H2SO4 = Na2SO4 + 2H2O
The mole ratios are ; - 2:1 :: 1:2
This tells you that two molar ratios of sodium hydroxide react with one molar ratio of sulphuric acid, to produce one molar ratio of sodium sulphate and two molar ratios of water.
NB If no number is shown , it is read as '1'.
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.
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.
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.
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.
