What is N2O7?
The general rule for determining the number of total atoms in a molecular formula is to add all the explicit subscripts shown plus 1 for each atom shown without an explicit subscript. In this formula there are no such atoms, and the total is 2 + 7 or 9 atoms.
Is SFl sulfur?
No sulfur is simply S (somtimes shown as S8). It looks like the formula there is SFI, which would be a compound of Sulfur, Fluorine, and Iodine.
What is the Lewis dot structure for Al2S3?
The chemical formula for aluminum selenide is Al2Se3. This is an ionic compound, so it is shown with 2 Al 2+ + 3 [Se] 2-. Around the Se are dot pairs on all four sides showing the complete transfer of electrons from the Al to the Se atoms.
What is the chemical formula of ethane?
C2H6 is the structure of ethane although the chemical formula can be shown in the displayed formula as well. This is shown by 6 C-H single bonds and 1 C-C single bond as carbon needs 4 bonds to other atoms.
What is the total number of electrons shown in this Lewis structure of carbon dioxide?
16 is the total number of electrons shown in the Lewis Structure of Carbon Dioxide.
What is shown by the structural formula of a polyatomic ion?
An arrangement of bonded atoms.
Which structural formula represents 4 electrons shared between two atoms?
A covalent bond that shares four electrons has a double bond between the atoms. A single bond is shown as a single dash, so a double bond is two dashes.
The element that make up a compound and the exact number of atom of each element in a unit of the compound can be shown in a?
The exact number of atoms of each element in a unit of the compound can be shown in a chemical formula. Through the use of symbols, a chemical formula represents the proportions of atoms in a compound. For example, the chemical formula for water H2O indicates there are two hydrogen atoms and one oxygen atom.
What is a composition of a compound shown by?
The chemical formula of the compound. This shows the composition directly in atomic ratios, which can be converted to mass ratios by using the atomic weights of each element in the compound.
What is N2O7?
The general rule for determining the number of total atoms in a molecular formula is to add all the explicit subscripts shown plus 1 for each atom shown without an explicit subscript. In this formula there are no such atoms, and the total is 2 + 7 or 9 atoms.

The elements that make up a compound and the number of atoms of each element in a unit of the compound can be shown in a?
A molecular formula shows this information. In sulfuric acid, for example, the formula is H2SO4 as you'll learn to write it. There is hydrogen (H), sulfur (S) and oxygen (O) in it, and there are specifically 2 atoms of hydrogen, one atom of sulfur, and 4 atoms of oxygen. You already guessed (and correctly!) that those numbers, the numerical subscripts, tell an investigator how many of those particular atoms are in the molecule of sulfuric acid.
Cathode rays were shown to be a stream of?
Cathode rays are electrons.
What is the chemical formula of ethane?
C2H6 is the structure of ethane although the chemical formula can be shown in the displayed formula as well. This is shown by 6 C-H single bonds and 1 C-C single bond as carbon needs 4 bonds to other atoms.

What is the total number of electrons shown in this Lewis structure of carbon dioxide?
16 is the total number of electrons shown in the Lewis Structure of Carbon Dioxide.
What is the total number of electrons shown in the Lewis structure of carbon dioxide?
16 is the total number of electrons shown in the Lewis Structure of Carbon Dioxide.
