What is the chemical combination of symbols that represents a compound?
Each element is given a symbol (a letter or a pair of letters where the first one is always a capitol letter and the second one is always a small letter). For instance the letter for Hydrogen is an 'H' and for Oxygen is an 'O'. When describing the formula for a chemical compound you use these symbols to say what elements it is made of and you follow each element with a number if there is more than one atom of that element in the compound. For instance water is made of one atom of Oxygen and two atoms of Hydrogen and therefore its chemical formula is: H2O
What is the advantage of using a chemical formula to represent a compound?
the big number out the front of the formula tells you how many molecules/moles/the amount of the overall molecule. the subscript (smaller) numbers after each letter say how many atoms of that element represented by the letter there are in ONE molecule of the compound.
Is AlCl3 a polar covalent bond?
First, the symbol for any chemical element properly begins with a capital, not a lower case letter. Second, assuming the formula is rectified to AlCl3, it is the formula for a chemical compound, and no chemical compound is any kind of chemical bond: A compound has bonds, or contains bonds, or illustrates bonding. With that out of the way, yes, the compound properly represented by the formula AlCl3 does indeed contain polar covalent bonds.
What is the name of the compound whose formula is HCL?
No such compound as 'HCL'. However, if you mean 'HCl'. Then it is hydrochloric acid. NB When writing chemical formula, a single letter element is ALWAYS a CAPITAL letter ( (H) Hydrogen) . A two letter element is ; first letter is a capital letter and the second letter is lower/small case ( (Cl) Chlorine) ; NOT (CL). This is the recognised international standard. NNB There is no element with a single letter 'L'.
What do you know about a chemical compound by looking at its chemical formula?
the number and kinds of atoms in the compoundIn an ionic compound, the formula gives the ions and their ratios in the crystal lattice. In a molecular compound, the formula gives the numbers of atoms of each element in a molecule.

What name for a compound with the formula cas?
The compound with the formula CAS does not have a specific name as CAS itself is an acronym for Chemical Abstracts Service, which is a division of the American Chemical Society that assigns unique identifiers to chemical substances. CAS is not a molecular formula but rather a system for identifying chemicals.

What is the chemical compound starting with the letter A?
ammonia
What do you know about a chemical compound by looking at its chemical formula?
the number and kinds of atoms in the compoundIn an ionic compound, the formula gives the ions and their ratios in the crystal lattice. In a molecular compound, the formula gives the numbers of atoms of each element in a molecule.
Compounds in a chemical equation represented by a?
In a chemical equation, the compounds represented by the letter "a" can vary depending on the specific reaction being described. It is a placeholder that can be substituted for the actual compound formula when balancing the equation. The coefficient of "a" indicates the number of moles of that compound involved in the reaction.
How do you indentify the elements in a compounds chemical formula?
To identify elements in a compound's chemical formula, look for capital letters. Each capital letter represents a different element. The number of each element in the formula is shown by the subscript next to the element's symbol.
What name is the compound CO?
CO is Carbon Monoxide. That is it contains one carbon and one oxygen. As a chemical symbol/formula do NOT confuse with 'Co' , Note the small case 'o'. This is the element 'Cobalt. In chemical formula . A one letter element is always a CAPITAL letter. A two letter element has first letter as a capital letter and the second letter is always lower/small case. E.g. H = Hydrogen He = Helium .
Is hcl a compound or element?
What is 'hcl'???? If you mean 'HCl'. then it is a compound of hydrogen combined to chlorine. To for form hydrogen chloride gas , or dissolved in weater to form hydrochloric acid. NB When writing chemical formula, single letter element are ALWAYS a CAPITAL letter , Hence hydrogen is 'H' not 'h' and similarly a two letter symbol ; first letter is a CAPITAL letter and the second letter is small /lower case. hence chlorine is 'Cl'. not 'cl'. This is the recognised IUPAC international standard and is shown in the Periodic Table.
