How to find Excess Reactant and Limiting Reactant

Limiting Reactant: “The reactant which is earlier consumed in a chemical reaction” is called limiting reactant. Or:    “The reactant which is completely consumed in a reaction to produce product when the reaction is over” is called limiting reactant. Limiting reactant is also known as limiting reagent. Excess Reactant: The substance whose some amount is left …

Law of Constant Composition(law of definite proportions)

Law of definite proportion: This law was put forward by French chemist Joseph Louis Proust in 1799. It states: According to the law of definite proportion “same compounds are always consisting of same elements combined in a same fixed ratio by mass.” For Example: Water (H2O) always contains hydrogen and oxygen in a ratio : …
