Interpretation:
For the chemical equation,
Concept Introduction:
The coefficients that are present in a balanced chemical equation is like subscripts in the chemical formula. These coefficients can be interpreted in two levels. One is a microscopic level and another is macroscopic level.
Microscopic level:
The coefficients that are present in a balanced chemical equation gives numerical relationship between the formula units consumed or produced when a
Macroscopic level:
In a balanced chemical equation, the coefficients gives information about the fixed molar ratios among the substance that is consumed or produced when a chemical reaction takes place.
