Transcribed Image Text:The plot below describes the formation of Element Z from Element X and Element Y over a period of time. Moles of Element X I Moles of Element Y Moles of Element Z 2.25 2.00 1.75 1.50 1.25 1.00 0.75 0.50 0.25 0.00 50 100 150 200 Time (seconds) Which statement best identifies and explains the determination of the mole ratio between the reactants? Moles of reactant or product
The mole ratio between the reactants X and Y is 1 mole of X to 1 mole of Y. This is evidenced by the fact that for every data point for Element X, there is a data point for Element Y.
The mole ratio between the reactants X and Y is 2 moles of Y to 1 mole of X. This is evidenced by the fact that Y decreases twice as much as X.
The mole ratio between the reactants X and Y cannot be determined by the plot. A balanced chemical equation must be used to determine the mole ratio of a reaction.
The mole ratio between the reactants X and Y is 2 moles of X to 1 mole of Y. This is evidenced by the fact that the reaction begins with fewer moles of Element X.
