How do you identify the number of elements in a compound?
The number of elements in a compound can be determined by looking at the chemical formula and identifying each element's symbol. For example, the compound CO2 has two elements, carbon and oxygen. Another example, glucose, has the formula C6H12O6, and has three elements, carbon, hydrogen, and oxygen.
What is the empirical formula for compound whose molecular formula is c2n2?
aromatic hydrocarbons
What is the empirical formula of the compound that is 75 carbon and 25 hydrogen?
The empirical formula of a compound is the simplest whole number ratio of the elements in the compound. In C75H25, the ratio of carbon to hydrogen is 75:25, which is equal to 3:1. Thus, the empirical formula is C3H.
The lowest whole number ratio of the elements in a compound is called the?
An empirical formula refers to the chemical formula that indicates the simplest ratio of atoms in a compound. Two different compounds may have the same empirical formula.
Which is not true about the chemical formula of a substances?
which is not true about the chemical formula of a sbstance? a.it gives the number and kinds of atoms present. b.it shows that a substance has a definite compound. c.it shows the elements present in the compound. d.it shows the phase of a substance.
What a compound formula tells about compound'?
It tells what elements are in a compound and the number of each type of atom in each molecule/formula unit.
Which formula of a compound has the smallest whole-number mole ratio of elements?
the empirical formula
How do you identify the number of elements in a compound?

What tells what elements a compound contains and the exaxt number of each element in a unit of that compound?
a chemical formula
What do you call number of atoms of different elements present in a compound?
molecular formula
Elements a compound contains and the exact number of the atoms of each element in a unit of that compound is called what?
That is called a formula.
How can the number of elements be identified within a compound?
Count the different chemical symbols in a compound's chemical formula to identify the number of elements. For instance, in the formula for sucrose (table sugar) C12H22O11 there are three elements -- C, H, and O. These represent carbon, hydrogen, and oxygen.
How are the words molecucle compound amd formula related?
A molecule is two or more elements bonded together, and a compound is a molecule containing at least two elements. The word formula fits in to tell you whether you have a compound or a molecule by telling you the number of elements (atoms) in the molecule.
What is the smallest whole number ratio of the elements in in ionic or covalent compound?
Formula unit
What is used to determine the number of each atom in an ionic compound?
The chemical formula of a chemical compound is established after a detailed chemical analysis.
What experimental evidence about a new compound must be known before its formula can be determined?
In a laboratory the mysterious compound is initially weighted and then will undergo reactions to be broken down into its constitutes. The individual elements or other compounds will be determined and then be weighed. Using information known on those elements and compounds, scientist will be able to discover the molar mass for each of them. Using the equation n = m/ M (mols = mass over (divided by) molar mass) they are able to determine the moles for each of the elements/compound. the unknown compound will be determined by the product with the lowest number of moles (closest to zero) have its number dividing all the other products (see it as for each mole of that element/compound there will be a requirement of N amount of moles from the other product(s)). This result will give the ratios for the constitutes in the unknown compound (the subscripts). This formula here will be the empirical formula (which may not be the actually formula for the reaction, it is the simplest ratio). Let the unknown compound be X. A and B are the resulting constitutes of X. After determining the correct mols of A and B where B moles is closest to 0, we divide Amols by Bmols and the resulting number is near a whole number. This number will be the subscript for A and will determine the empirical formula of X. If Bmols = 1 and Amols = 2 the unknown compound will have the empirical formula of A2B.
What information does the chemical formula for a compound provide about the submicroscopic structure of the compound?
You can find out the elements in it, and the number of each ions of each element. Example : Na2SO4 (Sodium Sulfate) You can find out from this formula that this compound contains : 2 Sodium ions (Na2) 1 Sulfide ion (S) 4 Oxide ion (O4)
