What is true about the First letter of a chemical symbol?
Not always... There are chemical elements beginning with the same letter - for example Copper and Cobalt. However - every chemical symbol does consist of two letters.
What is the rules for writing the symbol for an element?
The first or only letter of an element symbol must be capital; any other letter(s) must be lower case. (So far, there is never more than one other letter in the permanent symbol for any element, but the temporary names of some of the highest atomic weight elements often include two additional letters.)
What are two basic rules for writing symbols of elements?
The first letter must be capitalized and all others must remain lower case.
What is formula is H2O?
water, H2OBut in chemistry the symbols must be upper case unless the symbol consists of two letters (Magnesium, Mg) and then the first letter must be upper case.
What does the element CO stand for?
What is 'co'? You must be careful when writing chemical formula. They have different meaning and names. 'co'. Not known. Co is Cobalt. CO is carbon monoxide, Remember for all chemical formulae and symbols. A single letter symbol is ALWAYS a CAPITAL letter. e.g. H (hydrogen) A two letter symbol has a CAPITAL letter , to start, followed by a small case letter. e.g. Na (Nadium ; Sodium) No chemical formula has two small case letters., hence 'co' is a nonsense.
Why don't some chemical symbols not start with just their capital letter?
One reason that elements don't simply use the capital letter is that there are 118 known elements, but our alphabet only has 26 letters. Additionally, some elements have the same beginning letter, so we must use something else for the symbol. Carbon (C), copper (Cu), cobalt (Co), and calcium (Ca) can't all be represented by the same symbol. Finally, some chemical symbols are based on the names of elements in other languages, often Latin or Greek. For example lead's symbol, Pb comes from its Latin name, plumbum.
What is a ten letter word for substance on the left side of a chemical equation?
It should be reactants but it is 9 letters word so it must be Substrates.
How many atoms are there in the chemical?
"ch4" is not a proper chemical formula, because the atomic symbol for each element must begin (and may end) with a CAPITAL letter. The chemical formula CH4 contains 5 atoms, one of carbon and four of hydrogen.

What is a defintite chemical composition?
In mineralogy, definite chemical composition refers to a characteristic that a substance must possess to meet the definition of a mineral. It is the narrow parameter of chemical compositions that a substance must have to be described as a particular mineral separate from other minerals.
What is the chemical symbol for phosphorus pentachloride?
the pent in pentachloride refers to the chlorine in the molecule, therefore the molecular formula of the stated cemical is PCl5...although I'm not sure if this can exist because these two must form covalently (both need to gain electrons to gain full valence shell)
In a chemical reaction the reaction must do what?
The reaction must change the chemical nature of reactants.
