Elements and Compounds

None!!! There is no such substance as ' CaCL2 '.

There is no element with the symbol 'L'.

However, if you mean ' CaCl2 .

Then one molecule contains three atoms .

viz:

1 x Ca (Calcium)

2 x Cl( Chlorine).

The prefix '3' means three molar ratios. , or three molecules.

So in three molecules of CaCl2 there will be 3 x 3 = 9 atoms.

Archaically ; Sodium oxalate

IUPAC ; Sodium ethandiotate

Structurally, ; Na...O-(O=)C-C(=O)-O...Na

YES!!!

Any metal cation ionically combined to an acidic anion is a salt.

Sodium oxalate is the archaic name for sodium ethandioate.

Structurally,.

Na^(+) (-)O-(O=)C-C(=O)-O^(-) Na^(+)

Notice there are two sodium cations, one each at either end of the ethandioate anion.

'co' is neither a compound nor an element. Chemically it does NOT exist.

'CO' is the compound Carbon Monoxide ; a combination of carbon and oxygen.

'Co' is the element Cobalt ; found in the Periodic Table.

NB

Single letter elemental symbols are always written as a CAPITAL letter.

Double letter elemental symbols are written as ; first letter is a CAPITAL letter and the second letter is small/lower case letter.

There are NO elements/compounds with lower case letters throughout.. They DO NOT exist.

This is the international standard, and recognised world-wide.

'CoS' is Cobalt sulphide .

NOT as you correspondent put it as 'Carbon Monoxide'. Carbon monoxide formula is 'CO'.

Yes, both stainless steel and cold rolled steel are ferrous metals because they are primarily made of iron. Stainless steel contains chromium for corrosion resistance, while cold rolled steel is processed to improve strength and surface finish.

The formula for Hydrogen Nitrate is ' HNO3 ' . It is more commonly known as 'Nitric Acid'.

Natural flavoring is neither a compound nor an element; rather, it is a complex mixture of various compounds derived from natural sources. These flavorings are typically extracted from plants, fruits, spices, or other natural sources to enhance the taste of food and beverages. The specific composition can vary widely, making natural flavorings distinct from pure chemical compounds or elements.

YES!!!! It is a combination of one hydrogen , one carbon , and one nitrogen.

NB . Any substance that has two or more different elements in combination, is a compound.

The compound name of the formula HCN is hydrogen cyanide.

PCl5 is ' Phosphorus pentachloride '.

NB Do NOT confuse with PCl3 , which is ' Phosphorus trichloride ', a completely different substance.

NNB Phosphorus exhibits two different oxid'n states.

The compound with the formula AgOH is called silver hydroxide. It is a chemical compound composed of silver, oxygen, and hydrogen atoms.

The chemical formula for silver hydroxide is ' AgOH '.

Che,mical formula for magnesium hydroxide is ' Mg(OH)2 '.

NB The brackets MUST be shown , otherwise it indicates , one oxygen and two hydrogens

With the brackets it indicates that there are two oxygens and two hydrogens. .

The chemical formula for magnesium chloride is ' MgCl2 '.

Silver coins react with sulfur to create silver sulfide, resulting in a dark layer of tarnish. This reaction is triggered by sulfur in the air or materials like rubber, dulling the coin's natural shine. To prevent this, store coins in airtight, sulfur-free containers to preserve their finish.

Sulfur trioxide can react with moisture in the air to form sulfuric acid, a major component of acid rain. This acid rain can harm plants, aquatic life, and infrastructure, and contribute to the acidification of soil and water bodies. Sulfur trioxide emissions also contribute to air pollution and can have adverse effects on human health.

Sulphur dioxide is a naturally hydroscopic gas.

When rain falls from the clouds, it dissolves sulphur dioxide to form a mild solution of sulphurous acid.

It is the droplets of sulphurous acid that is 'acid rain'.

Here is the chemical reaction eq'n.

H2O(l) + SO2(g) = H2SO3(aq)

Feviquick is NOT a chemical compound (it is a mixture) so its chemical formula cannot be obtained.

CaNO32 ??? No such molecule. This indicates that there are '32' oxygen atoms in the molecule.

I think you mean ' Ca(NO3)2 ' (Calcium nitrate) . Note the use and position of the brackets. This indicates that there are two nitrate anions in the molecule.

The formula ' Ca(NO3)2 ' tells us that there are ;=

1 x Ca^(2+) ; ONE calcium cation . (NOT atom).

2 x NO3^(-) ; TWO nitrate anions.

Each nitrate anion has one nitrogen ATOM and three oxygen ATOMS bonded covalently. Leaving one 'spare' electron to bond ionically with the calcium cation.

Since the calcium cation has a charge of '2+ ' , then we MUST have TWO nitrate anions each of charge ' - ' , in order to balance the charges.

So overall you have

1 x calcium cation.

2 x nitrogen atoms

2 x 3 = 6 oxygen atoms.

NB THe use of brackets to indicate multiple units is universal .

NNB When an atom gains or loses electrons, to becomes a charged species, it is no longer an atom but an ION .

A tincture is a concentrated herbal extract that is typically made by soaking herbs in alcohol. Tinctures are known for their long shelf life and quick absorption into the body, making them an effective and convenient way to consume herbal remedies and supplements. They are commonly used in herbal medicine for their potent and fast-acting properties.

H2O is WATER . At room temperature and air pressure, it is a liquid.

No copper kettles are coated with special chemicals which prevents steam reacting with it just like aluminum forms an oxide layer which prevents it from further reacting. If no layer were put on the kettle it would turn greenish because copper would have reacted.................

Hope I was useful ;-)

Kyle.

There is ONLY ONE product .. It is WATER.

When hydrogen is combusted(burned) in oxygen or air(oxygen), then it form water.

Here is the rection eq'n

2H2(g) + O2(g) ==> 2H2O(l)

firstly the protons are in the nucleus of an atom. there are 16 protons there. the number of electrons is the same as the number of protons. the electron arrangement is as follows:

first shell-2 electrons

second shell - 8 electrons

third shell - 6 electrons

this can also be written as 2,8,6
