Question

If the spectroscopic evidence shows the presence of 0.1 mol of carbon dioxide, what can be concluded about the stoichiometry of the reaction?

A) The ratio of moles of carbon dioxide to carbon monoxide is 1:1.
B) The ratio of moles of carbon dioxide to water vapor is 1:2.
C) The ratio of moles of carbon dioxide to the unknown compound is 1:1.
D) The ratio of moles of carbon dioxide to sodium ethoxide is 1:1.
Please select the correct option.

Answer 1

This implies a direct and equal relationship between the amounts of carbon dioxide and the unknown compound in the reaction, making option C the most accurate representation of the stoichiometry observed in the given scenario. Therefore, The correct option is C) The ratio of moles of carbon dioxide to the unknown compound is 1:1. because the given spectroscopic evidence indicates the presence of 0.1 mol of carbon dioxide, and the ratio of moles of carbon dioxide to the unknown compound is specified as 1:1.

Step-by-step explanation:

Spectroscopic evidence indicating the presence of 0.1 mol of carbon dioxide provides critical information about the stoichiometry of the reaction. To determine the correct ratio, we need to consider the balanced chemical equation for the reaction. Let's denote the moles of carbon dioxide as
`n\[CO_2\]`, moles of carbon monoxide as
`n\[CO\]`, moles of water vapor as
`n\[H_2O\]`, moles of the unknown compound as
`n\[X\]`, and moles of sodium ethoxide as
`n\[NaOC_2H_5\]`. The general form of the reaction is given by:

`\[aCO_2 + bCO + cH_2O + dX + eNaOC_2H_5 \rightarrow \text{products}\]`

Since we are given that there are 0.1 mol of carbon dioxide
`(n\[CO_2\] = 0.1),` and the ratio is 1:1 with the unknown compound
`(n\[CO_2\] = n\[X\])`, the correct option is C.

This conclusion is drawn based on the principle of stoichiometry, where the coefficients in the balanced equation represent the molar ratios of the reactants and products. The 1:1 ratio implies that for every mole of carbon dioxide consumed or produced, one mole of the unknown compound is involved in the reaction. This information is crucial for understanding the quantitative relationships between different substances in a chemical reaction, providing a fundamental basis for further analysis and interpretation of the reaction mechanism.
