Balancing Equation

Chemical Reactions
Chemical Reaction is known as chemic change. It is a process in which the chemical composition of a substance changes. This indicates that the number of tinges that make-up all(prenominal) molecules, the element of the atom that make-up the molecules, or both were changed.
A chemical answer involves a reactant(s) and a product(s). Reactant, also called reagent is the substance that undergoes chemical reaction. harvest-tide is the substance that was created when the reactant underwent chemical reactions.
A chemical equation is an convention that sights the reactants involved and products that were created in a chemical reactyion. A chemical reaction is typically in the format:

I. Formulas show alchemy at a give birthstill. Equations show chemistry in action.
A. Equations show:
1. the reactants which enter into a reaction.
2. the products which are formed by the reaction.
3. the amounts of each substance used and each substance produced.
B. Two key principles to remember:
1. Every chemical compound has a statute which cannot be altered.
2. A chemical reaction must line for every atom that is used. This is an application of the Law of Conservation of depicted object which states that in a chemical reaction atoms are neither created nor destroyed.
C.



Some things to remember about writing equations:
1. The diatomic elements when they stand alone are always written H2, N2, O2, F2, Cl2, Br2, I2
2. The sign,  ?  , means yields and shows the nidus of the action.
3. A small delta, (?), above the arrow shows that heat has been added.
4. A double arrow,  ?  , shows that the reaction is reversible and can go in both directions.
5. Before beginning to balance an equation, check each law to see that it is correct. NEVER change a formula during the balancing of an equation.
6. Balancing is done by placing coefficients in forward of the formulas to insure the same number of atoms of each element on both sides of the...If you want to get a full essay, localise it on our website: Orderessay
