if a original compound is contaminated with a thermally stable compound. will the reporrted mole ratio of carbon dioxide to calcium oxide be too high, too low or uunaffected as a result of the contamination.

To determine the impact of a contamination on the reported mole ratio of carbon dioxide (CO2) to calcium oxide (CaO), we need to consider the properties of the contaminant. Specifically, we need to assess whether the contaminant will alter the amount of CO2 or CaO in the sample.

If the contaminant is thermally stable, it means that it will not decompose or react at the temperature of measurement. In this case, the presence of a thermally stable contaminant will not affect the reported mole ratio of CO2 to CaO. The contaminant will not engage in any reactions that generate or consume CO2 or CaO during the analysis.

Therefore, the reported mole ratio will be unaffected by the presence of a thermally stable contaminant. It will remain the same as if the sample were uncontaminated, assuming other factors (such as the accuracy of the measurement technique) are consistent.

However, it's worth noting that if the contaminant is reactive or chemically unstable at the temperature of measurement, it could potentially interfere with the analysis and affect the reported mole ratio. In such cases, additional steps may be required to account for the presence of the contaminant or to remove it before conducting the analysis.
