- Answer 1 To balance an equation means that there are the same number of each element on each side. The reason a subscript cannot change is that it represents the amount of an … element within a certain compound in relation to any other elements. If that ratio changes, it is no longer the same compound.

Chemical Formula Chemical Formula. Chemical Formula-Written combination of element symbols that represents the atoms combined in a chemical compound. The Chemical Formula is an indication of the makeup of a compound in terms of the kinds of atoms and their relative numbers.aking error of capitalizing the second letter of an elements symbol can dramatically alter the meaning of a chemical formula. When we attempt to write a formula it is important to know whether the substance actually exists.

- A chemical equation is basically putting compounds, elements, or mixtures together to form something new. When this happens it is a chemical change because a new solution is being formed. For example: 2H2+02---->2H20. The 2H2 is just multiple hydrogen elements being combined with 2 oxygen elements.

Chemical Equations To write the chemical equation for this reaction, we would place the substances reacting (the reactants) on the left side of an equation with an arrow pointing to the substances being formed on the right side of the equation (the products).n writing chemical equations, the number in front of the molecule 's symbol (called a coefficient) indicates the number of molecules participating in the reaction. If no coefficient appears in front of a molecule, we interpret this as meaning one.

Chemical equations A word equation represents the ingredients of the reaction. The reactants and products are written in words. The '+' symbol shows the separate ingredients, while the ' ' symbol stands for 'reacts to form'. Chemical equations go a bit further by being more specific about the formulae involved.

- S=[Fe]=S. Molecular Formula A chemical formula is a way of expressing information about the proportions of atoms that constitute a particular chemical compound, using a single line of chemical element symbols and numbers. PubChem uses the Hill system whereby the number of carbon atoms in a molecule is indicated first, the number of hydrogen atoms second, and then the number of all other chemical elements in alphabetical order. When the formula contains no carbon, all the elements, including hydrogen, are listed alphabetically. Sources other than PubChem may include a variant of the formula that is more structural or natural to chemists, for example H2SO4 for sulfuric acid, rather than the Hill version H2O4S.

- A chemical formula is a representation of the elements in a molecule. Although the word formula connotes an equation, chemical formula are not to be confused with chemical equations, which describe multiple molecules at once.olecular Formula. The molecular chemical formula uses subscripts to count the number of elements in a molecule, e.g. H2O, where the 2 is a subscript. One variant is to clump element symbols together in the order they appear in the molecule, e.g. CH3-O-CH3 or CH3OCH3, instead of C2H6O.

Subscript and superscript In professional typography, subscript and superscript characters are not simply ordinary characters reduced in size; to keep them visually consistent with the rest of the font, typeface designers make them slightly heavier than a reduced-size character would be.he second typeface is Myriad Pro; the superscript is about 60% of the original characters, raised by about 44% above the baseline.). A subscript or superscript is a number, figure, symbol, or indicator that is smaller than the normal line of type and is set slightly below or above it.
