The correct formula is CuSO4 , and its name is 'copper sulphate' .
'Cu2SO4' does NOT exist.
To write the chemical formula of a compound with polyatomic ions, first determine the charge of each ion. Then, balance the charges by crisscrossing the numerical values of the charges to determine the subscripts of each ion in the formula. Finally, write the formula with the proper subscripts for each ion to balance the charges.
The chemical formula for calcium bromide is CaBr2.
The smallest numbers of ions of the proper kind that provide a correct elemental composition for the compound with electrical charges balanced. For example, magnesium cations have a charge of +2 and chloride anions have a charge of -1, so that two chloride anions and one magnesium cation are required to provide electrical neutrality, resulting in a formula of MgCl2.
The chemical formula of lip gloss can vary depending on the ingredients used, but common components include oils, waxes, colorants, and flavorings. These ingredients can include compounds like hydrogenated polyisobutene, ozokerite, and flavor oils, resulting in a complex mixture rather than a single chemical formula.
Paraffin wax is a colorless and translucent hard wax which is mainly composed of a mixture of alkanes. This mixture indicates solid straight-chain hydrocarbons with the general formula CnH2n+2.
this is a theoretical compound practically not possible because carbon can not form five bonds.
H2o
h20
Acid fuchsine is not a pure compound but a mixture of (many isomers of) sulfonated basic fuchsine. So there isn't a proper chemical formula for this mixture.However the compound 'fuchsine' (sic!) is named:" 4-[(4-Aminophenyl)-(4-imino-1-cyclohexa-2,5-dienylidene)methyl]aniline hydrochloride "it may also be called:" Rosaniline hydrochloride "Its chemical formula is presented in the 'Related links' area just below this answer (cit. wikipedia).

The proper name is potassium fluoride. The formula is KF.
That's the chemical formula for Nitric acid.
Sodium dihydrogen carbonate is not a proper chemical name and therefore has no formula, because carbonate anions have only two negative charges and therefore can not form a neutral compound with one sodium atom and two hydrogen atoms. The closest analogous compound is sodium hydrogen carbonate, which has the formula NaHCO3.
You think probable to chemical reactions.
"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.
