Introduction To Chemical Reactions and Equation

   CHEMICAL REACTION

A chemical reaction is a process in which one or more substances, also called reactants, are converted to one or more different substances, known as products.

For example: Rusting of iron, the setting of milk into curd, digestion of food, respiration, etc.




A chemical equation is the symbolic representation of a chemical reaction in the form of symbols and formulae, wherein the reactant entities are given on the left-hand side and the product entities on the right-hand side with a plus sign between the entities in both the reactants and the products.   

SOME EXAMPLES OF CHEMICAL REACTION

  • Combustion.
  • Oxidation (rusting)
  • Decomposition or fermentation.
  • Cooking an egg.
  • Photosynthesis.
  • Reacting acids and bases together.
  • Chemical batteries.
  • Digestion.

Combination Reaction

Image
  A combination reaction  also  recognized  as a synthesis  reaction,  is a reaction where two or more elements or compounds (reactants)  merge  to form a single compound (product). Such  reactions are represented  by equations of the  subsequent  form: X + Y →  XY . The combination of two or more elements to  construct  one compound is  named  a combination reaction. In  alternative  words, when two or more elements or compounds react  so as  to  construct  one single compound, then the chemical reaction that takes place is  hailed  a combination reaction. Between elements C + O2 → CO2. Carbon  finally  burnt in oxygen yields carbon dioxide. Between compounds  CaO  + H2O → Ca(OH)2. Calcium oxide (lime)  mixed  with water gives calcium hydroxide (slaked lime). Between elements and compounds 2CO + O2 → 2CO2. Oxygen combines with carbon monoxide, And carbon  dioxide is formed .  There is no  definitive  number of reactants in a combination reaction. What is a  Combination   Reaction ? A

How To Balance a Chemical Equation

  1 Method 1 of 2: Doing a Traditional Balance 1 Write down your given equation.  For this example, you will use: C 3 H 8  + O 2  --> H 2 O + CO 2 This reaction occurs when propane (C 3 H 8 ) is burned in the presence of oxygen to produce water and carbon dioxide. 2 Write down the number of atoms per element.  Do this for each side of the equation. Look at the subscripts next to each atom to find the number of atoms in the equation. When writing it out, it's a good idea to connect it back to the original equation, noting how each element appears. [1] For example, you have 3 oxygen atoms on the right side, but that total results from addition. Left side: 3 carbon (C3), 8 hydrogen (H8) and 2 oxygen (O2). Right side: 1 carbon (C), 2 hydrogen (H2) and 3 oxygen (O + O2). Advertisement 3 Save hydrogen and oxygen for last, as they are often on both sides.  Hydrogen and oxygen are both common in molecules, so it's likely that you'll have them on both sides of your equation.
