A chemical formula or molecular formula is a way of expressing information about the atoms that constitute a particular chemical compound.
The chemical formula identifies each constituent element by its chemical symbol and indicates the number of atoms of each element found in each discrete molecule of that compound. If a molecule contains more than one atom of a particular element, this quantity is indicated using a subscript after the chemical symbol (although 18th-century books often used superscripts) and also can be combined by more chemical elements. For example, methane, a small molecule consisting of one carbon atom and four hydrogen atoms, has the chemical formula CH4. The sugar molecule glucose has six carbon atoms, twelve hydrogen atoms and six oxygen atoms, so its chemical formula is C6H12O6.
Chemical formulas may be used in chemical equations to describe chemical reactions. For ionic compounds and other non-molecular substances an empirical formula may be used, in which the subscripts indicate the ratio of the elements.
The 19th-century Swedish chemist Jöns Jacob Berzelius worked out this system for writing chemical formulas.
The alternative is to write out in words the amounts and names of each reactant and product, and would not include chemical formulas. Using symbols to represent a chemical reaction as a chemical equation makes it easier to understand and to work with a chemical reaction. Take for example the reaction between hydrogen and oxygen to produce water. The word equation would be two molecules (or moles) of hydrogen gas react with one molecule (or mole) of oxygen to produce two molecules (or moles) of water. Compare that to the chemical equation, which is 2H2 + O2 --> 2H2O.
yes, chemical equations describe chemical reactions in terms of chemical formulas (i.e. 2C+2H-->2CH) this answer may not be right, i was dared to answer it
energy is given off or absorbed
In chemical reactions, chemical bonds ? between some particles and ? between other particals
They are usually much easier to write, and they show what happens to the atoms. Also, it looks more official and scientific. (-:
the change in the nuclei of the atoms.
energy can be made via two common chemical processes the first is? and the second is?
You need to be more specific with this question, forced chemical reactions? What happens to the patron? What happens to the drink?
it is broken down to fuel chemical reactions & is created by chemical reactions.
new products should be formed
This a normal product in many chemical reactions.
The chemical reactions of sulfuric acid are chemical changes.
The result is an illness.
Some chemical reactions in the body do move back and forth. Other chemical reactions can only be pressed one way because when they are pushed in the other direction nothing happens.
It is impossible to answer as there are at least 4,000.
energy is given off or absorbed
all chemical reactions.....they burn and dissolve
In chemical reactions, chemical bonds ? between some particles and ? between other particals
The product inhibits the activity of the first enzyme
