Question

1. a correct assumption that is made when using stoichiometry for a theoretical reaction is that i, and an incorrect assumption about reaction stoichiometry is ii. the statement above is best completed by the answers in row: row i ii the reaction goes to the masses react in whole number completion ratios the reaction goes to the reactions are spontaneous completion the yield of the reaction can the reactions are spontaneous vary the yield of the reaction can the masses react in whole number vary ratios

Explanation:

Step1: Recall stoichiometry principles

Stoichiometry for a theoretical reaction assumes the reaction goes to completion to calculate amounts of reactants and products based on mole - ratios.

Step2: Analyze incorrect assumptions

The fact that reactions are spontaneous is not an assumption in stoichiometry calculations. Stoichiometry is about the quantitative relationships between reactants and products, and while masses react in definite mole - ratios (not necessarily whole - number mass ratios in a non - molar context), the spontaneity of a reaction is determined by factors like Gibbs free energy and is not part of stoichiometric assumptions.

Answer:

the reaction goes to completion; the reactions are spontaneous
