What is the structural formula for propanamide?
I'm not certain but I believe it's this: CH3CH2CO(NH2) My main uncertainty is the use of brackets, I think it may be needed because the amide molecule is on the Carbon and not attached to the oxygen, but I don't know if -O- is possible here, certainly propanamide contains a peptide bond so the brackets make certain.
What is Bi2SO43?
Bismuth sulphate. NB The formula should be written as Bi2(SO4)3 . Note the use of the brackets, otherwise it indicates that there are '43' oxygen atoms in the molecule.
CoCl2 is this a single atom diatomic molecule molecule or a formula unit?
it is a formula unit
What is the name for the molecule ch3?
CH3 is not the formula for any stable molecule; it is the formula of a "methyl radical".
Is bromine a formula unit or molecule?
Br is a molecule.
What indicates which workbook cells are included in a formula calculation?
The name of the workbook will be enclosed in square brackets, indicating it is another workbook.

Is enclosed in parentheses in a formula with a function?
The arguments of the function are contained in the brackets of the function. For example: =Sum(A5:B10) All functions have brackets, though not all need to have something in the brackets. For example: =Now() Formulas can also have brackets to change the precedence of operators. See the related question below.

Does a chemical formula represent one molecule of a certain compound?
Yes
Why are brackets necessary in chemistry?
Brackets are necessary as it helps to differentiate between the different parts of chemical formulae. For example, take ammonium hydrogen phosphate. The chemical formula is: (NH4)2HPO4. The brackets signify that there are two NH4 atoms in the formula. If the brackets weren't there then it would be: NH42HPO3. Now it looks like that the one nitrogen atom is bonded to 42 hydrogen atoms and one phosphate molecule.
Does the chemical formula P2O5 represent a molecule or a formula unit?
Molecule
What is Bi2SO43?
Bismuth sulphate. NB The formula should be written as Bi2(SO4)3 . Note the use of the brackets, otherwise it indicates that there are '43' oxygen atoms in the molecule.
What is the formula for carbon and chlorine?
the chemical formula for carbon is C and for chlorine is Cl.
CoCl2 is this a single atom diatomic molecule molecule or a formula unit?
it is a formula unit
Explain the difference between molecule and formula unit?
The formula unit is the representation of a molecule.
What is the chemical formula for the molecule?
A molecule contain two or more atoms of chemical elements; each molecule has a specific formula.
