Unformatted text preview: chemical reactions and conversions. It also helped us understand the chemical properties of substances in mixtures and use equations to balance of reagents and products. A mixture was weighed out to be _____________. The HCl was measured out to 12 mL. The mixture was set into a small beaker and the HCl was poured on top of it. The chemical reaction began to take place; the substances began to bubble and sputter, releasing a slight amount of carbon dioxide (CO2) into the air. When the fizzing concluded, we weighed what was left. Using the equations from earlier, we were able to discover the mass percent of the mixture and its components. Using equations like [HCl mass+mixture mass=initial mass] and [initial mass-final mass=CO2 mass] and [with mass of CO2, you can find mass of NaHCO3] and [with mass of NaHCO3, you can find the percentage of NaHCO3]...
