Steps in balancing the information
- Step 1: Write the unbalanced equation
- Step 2: Find the coefficient to balance the equation.
- The coefficient should be reduced to the smallest whole number
A balanced equation should be obeying the law of conservation of mass. Law of conservation of mass states that, the number of atoms remains constant throughout the reaction, simply it can be stated as follows, “during a chemical reaction atoms are neither be created nor be destroyed”.
Oxidation: Losing electrons, increasing oxidation number.
Reduction: Gaining electron, decreasing oxidation number.
Oxidizing agent is a substance that removes electrons from another reactant in a chemical reaction and so it is reduced by taking electron onto itself and the reactant is oxidized by having its electron taken away.
Reducing agent is the element or compound in a
