Which of the following information is conveyed by chemical reaction?
Which of the following information is conveyed by chemical reaction?
The correct option is
A
The masses of the reactants and products involved in the reaction.
A chemical equation conveys both qualitative and quantitative information. Qualitatively, a chemical equation tells the names of the various reactants and the products.
From a chemical reaction, we can determine the mass of reactants and products because in a reaction stoichiometric is specified. Using stoichiometry we can calculate the mass of reactant required to prepare the desired amount of product.
The Law of conservation of mass governs the balancing of a chemical equation. According to this, mass can neither be created nor be destroyed in a chemical reaction
Obeying this law total mass of the elements or molecules present on the reactant side should be equal to the total mass of elements or molecules present on the product side. If the chemical equation is not balanced, the law of conservation is not applicable.
Hence, a balanced equation conveys basic knowledge about the respective formula of the reactant and product, their respective masses, and the total number of molecules present in the reaction.
