Please identify the substance. 

Guess: Calcium Carbonate?

**Physical Description:** This substance is a colorless solid with low solubility in water (~0.01 g/L at 25°C). It is typically found in rocks, minerals, and biologically-derived sources. It reacts with strong acids to release carbon dioxide. **Chemical Information:** - **Observed Melting Point:** 1500-2400°F (decomposes) - **Observed Boiling Point:** Not available - **Estimated Molar Mass:** 100 g/mol - **Density:** 2.7 g/cm³ at room temperature (most stable form) - **Solubility in Water:** Practically insoluble **Other Properties:** The substance has a chalky taste, is soluble in dilute acids, non-corrosive, stable in air, and has an indefinite shelf life. **Spectroscopic Information:** No ^1H or ^13C NMR data are available for this compound. The FTIR data is detailed below. **FTIR Spectrum Explanation:** The FTIR spectrum displays three main peaks: - At 1464 cm⁻¹ with 12% transmittance - At 876 cm⁻¹ with 55% transmittance - At 713 cm⁻¹ with 88% transmittance These peaks indicate the presence of specific molecular vibrations, which help identify chemical functional groups in the substance.
