The number of atoms is determined by the subscript attached to the symbol. They hadnt learned the exact chemical formula of the universe but they had learned how to run the blamed thing from practicing on the college during study hours. A balanced equation is reduced to the lowest whole number coefficients.
Instead of showing each electron which is shared a line is used to designate an electron pair shared between the atoms.
There are different types of chemical formulas and each type. There are 12 carbon C atoms 22 hydrogen H atoms and 11 oxygen O atoms. Lets take a look at the chemical formula of sucrose. 392 A x B y n A n x B n x For example consider a covalent compound whose empirical formula is determined to be CH 2 O.
