Question

what are stoichiometric coefficients?​

Answer 1

Stoichiometric coefficient (ν) is the number appearing before the symbol for each compound in the equation for a chemical reaction. By convention, it is negative for reactants and positive for products.

Stoichiometric coefficients describe the stoichiometry of the chemical reaction.

aA + bB →← cC + dD

In this equation, a, b, c and d are called as Stoichiometric coefficients of the A, B, C and D respectively.

Answer 2

Stoichiometric Coefficients. In a balanced reaction, both sides of the equation have the same number of elements. The stoichiometric coefficient is the number written in front of atoms, ion and molecules in a chemical reaction to balance the number of each element on both the reactant and product sides of the equation.
