Question

what information do we get from a balanced chemical equation

Answer 1

Answer:

I) A chemical equation gives information about the reactants and products through their symbols and formulae.

II) The ratio of molecules and reactants.

III) As molecular masses are expressed in grams in 'Unified Masses' (U), the relative masses of reactants and products.

IV) Using molar mass and Avagadro's number we can calculate the number of molecules and atoms of different substances from the equation. It gives information about relative masses of reactants and products from the equation we get,

a) mass-mass relationship

b) mass-volume relationship

c) volume-volume relationship

d) mass-volume-number of molecules relationship etc.
