Interpreting a balanced chemical equation
Answers
hey mate....,
A Balanced Chemical Equation explains about reactants, products and their physical states during the reaction.
A chemical equation gives information about
The reactants and products through their symbols and formulae.
The ratio of molecules of reactants and products.
The relative masses of reactants and products (as molecular masses are expressed in "Unified Masses" (U)).
If the masses are expressed in grams then the equation also gives the molar ratios of the reactants and products.
If gases are involved, we can equate their masses to their volumes and calculate the volumes or those gases liberated at given condition of temperature and pressure using molar mass and molar volume relationship.
Using molar mass and Avagadro's number we can calculate the number of molecules and atoms of different substances from the equation.
From the equation we get relationships...
mass-mass
mass-volume
volume-volume
mass-volume-number of molecules etc.,
