Which information is essential to perform stoichiometric calculations for a chemical reaction?
A balanced chemical equation
A balanced chemical equation, which shows the correct mole ratios of reactants and products, is essential for performing stoichiometric calculations.
The colour of reactants, reaction temperature and type of apparatus do not provide the quantitative information needed for stoichiometry.
Hence, 'A balanced chemical equation' is the correct answer.
