Classroom Resources | Reactions & Stoichiometry - Estate Sales In Marshall, Tx

What are the criteria (specifications) for a successful solution? Though I had used a version of the decomposition of sodium bicarbonate lab in our stoichiometry unit for years, with consistent results, what the ADI book provided was a surprisingly different and more creative approach. Swirl gently to mix. Using less baking soda, for instance, produces less carbon dioxide gas because there are fewer atoms from the baking soda to produce the carbon dioxide. I understand that the correct equation is supposed to be the first one where sodium carbonate was produced. For example, they may ask: What is the need or desire that underlies the problem? If you take the first route, I'm sure we can come up with some convincing explanations. Also, the baking soda should be added to the cylinder first. Scientific questions arise in a variety of ways. Continue to project the chemical equation as you and students count the number of atoms on both the reactant side and product side of the equation. Use a graduated cylinder to measure 10 mL of vinegar. In this demonstration, students will observe a reaction between baking soda and vinegar in the presence of a burning candle.

Baking Soda Stoichiometry Lab Answer Key Pdf

1) Their lack of prior knowledge makes all four options appear plausible. While they might be lacking in these areas, they are not completely clueless.

What could you change to create a foam that rises as close as possible to the top of the cylinder without overflowing? This might work for a while, as long as there is extra vinegar, but eventually there would be no atoms left of vinegar to react with the extra baking soda, so no more carbon dioxide would be produced. Once all of the solid has dissolved, continue to add HCl but now do it dropwise (agitating the test tube after each drop). 50 grams of sodium bicarbonate is added, it is the same change as 0. Fill another clean and dry test tube with NaHCO3 and begin again.

Baking Soda Stoichiometry Lab Answer Key Graph

In addition, you will calculate the theoretical amount (also called the theoretical yield) of NaCl that can be produced and compare the two by calculating a percent yield. As novices, they have no idea how to confidently predict the products of such a reaction. Be sure you and the students wear properly fitting goggles. In this lesson, students will extract DNA from strawberries and analyze evidence to figure out who perpetrated a petty crime. Why, on the molecular level, does changing the amount of baking soda or vinegar affect the amount of carbon dioxide gas produced? During our reactions unit, they had learned about testing for certain gases using a flame test. Stoked About Stoich - Sodium Bicarbonate and Citric Acid. Analyzing data in 9–12 builds on K–8 and progresses to introducing more detailed statistical analysis, the comparison of data sets for consistency, and the use of models to generate and analyze data. Maybe there is another reaction that also happens, perhaps involving the air, or the crucible, or the gas from the bunsen burner. In this demonstration, students will observe that the vapor of an extinguished candle flame is ignitable. They will also be able to explain that the equal number of atoms on each side of the equation shows that mass is conserved during a chemical reaction. Make a detergent solution by adding 1 teaspoon of liquid dish detergent to 2 tablespoons of water. The chemical formula for a substance is unique to that substance and defines what it is.

Decomposition Of Baking Soda Stoichiometry

While the method used for groups to communicate their argument to others can easily vary from teacher to teacher, I decided to have 2-3 groups come together and present their findings to each other. As the temperature of the cake batter reaches approximately 50oC, the baking soda decomposes and carbon dioxide is released. Students might mention variables such as: The amount of vinegar, detergent, or baking soda and the order in which the substances are added to the graduated cylinder. When a drop of HCl produces no additional CO2 bubbles, the reaction is complete and no more HCl should be added. The mass of NaHCO3 in each test tube should be ~ 0. They can be inspired by a model's or theory's predictions or by attempts to extend or refine a model or theory (e. g., How does the particle model of matter explain the incompressibility of liquids? In this lab, students will explore simulated reactions that contribute to chemical weathering of certain rocks as it appears in nature. Can two or more ideas be combined to produce a better solution?

Look at the teacher version of the activity sheet to find the questions and answers. Students will observe chemical change and investigate real-world connections to this lab. Record the mass (test tube + NaCl) on the report sheet data table. Every test should be conducted the same way. Constructing explanations and designing solutions in 9–12 builds on K–8 experiences and progresses to explanations and designs that are supported by multiple and independent student-generated sources of evidence consistent with scientific ideas, principles, and theories.

Mass is conserved in a chemical reaction. Though I demonstrated some basic safety tips, how to set up their apparatus, and the general approach to performing the reaction, the bulk of the experimental design was going to be on them. Ask students about vinegar: - Acetic acid mixed with water is vinegar. Place 50 mL of water in a 100 mL graduated cylinder. Materials for Each Group. I was truly amazed by how many groups did not take the time to think about how they were going to collect their mass data. Select Done in the top right corne to save the file. 4) Developing an argument from evidence. I had mentioned that one of the characteristics I liked about this lab was the student involvement in experimental design. With respect to materials, I gave them the following list of equipment and the chemical they were going to consume. In this lab, students will investigate how an acidic, vinegar based solution can help to get "dirty" pennies clean. The theoretical amount of NaCl that can be produced from a weighed amount of NaHCO3 and excess HCl is given by: The percent yield is given by: USE OF LABORATORY BALANCE. In fact, the agreement with that hypothesis is quite strong, and the agreement with the supposedly correct hypothesis is terrible.
