A 2.000 g mixture contained NH4Cl, NaCl, and SiO2. The entire mixture was heated over a Fisher burner for 10 minutes until a constant mass was obtained. It was then stirred into DI water. The remaining solid was filtered, washed with DI water and dried. The mass of the solid residue in the filter paper was 0.709 g. What conclusion can be made? Select one: The mixture was 35.5% SiO₂. The mixture was 35.5% NaCl. O The mixture was 64.6% SiO2. The mixture was 64.6% NaCl.
