Write the step in balancing a chemical equation with an example. |
|
Answer» SOLUTION :Example :`Mg+O_(2)to MgO`is an UNBALANCED chemical equation . THISIS called skeletal equation .A systematic procedure should be following for balancing the chemical equation. StepI The number of times an element occurs on both sides is counted . the element which appears the least number of times should be balanced first. StepII Among THEELEMENTS with same frequency of occurrences , the metallic element is balanced first followed by NONMETALLIC element. Step IIIHydrogen and oxygen is balanced at the end. Examples :R""P `Mg+O_(2)toMgO` `1-Mg-1` `2-O-1` `Mg+O_(2)to2MgO` `1-Mg-2` `2-O-2` `2Mg+O_(2)to2MgO` |
