Presentation Transcript

  1. Decomposition of Baking soda Lab • Purpose: • Your purpose will address the following: • Explain what a decomposition is and how to identify it visually. • Explain what stoichiometry is and what purpose it serves in chemistry.

  2. Possible Chemical Reactions • Translate the three chemical reactions into balanced formula equations. • 1. Sodium bicarbonate (s)  sodium hydroxide (s) and carbon dioxide (g)

  3. Sodium bicarbonate (s)  sodium oxide (s) + carbon dioxide (g) + water (g) • Sodium bicarbonate (s)  sodium carbonate (s) + carbon dioxide (g) + water (g)

  4. Data Table • Provide an organized data table of all measurements taken in lab with proper units.

  5. Calculations • For each of the three possible reactions, calculate the mass (g) of solid produced. Let’s do the first one as our example.

  6. Conclusion • Based upon your calculation results, identify the correct reaction and explain how you determined which reaction was correct out of the three? • All three reactions involve the production of carbon dioxide gas. • 1. First, if the carbon dioxide had been collected, what mass would be expected? Second, purpose a way to collect the gas. Draw a picture of how you would collect it and explain your drawing. If you get stuck, research how to collect carbon dioxide gas.
