Get, Create, Make and Sign lab 23 decomposition of baking soda stoichiometry answers. Preview of sample stoich lab answer key. Set up a Bunsen burner to evaporate all of the water from each test tube. 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. Three complete lessons: each lesson includes student notes, detailed teacher notes, check for understanding exit tickets, and homework. Download the student activity sheet, and distribute one per student when specified in the activity.
Can you add the baking soda first and then the vinegar on one trial and then switch it for the other trials? Hands-on inquiry can be another practical and tangible tool. 30 grams of citric acid. The students are provided with four different balanced chemical equations that could explain how the atoms are rearranged during this decomposition. USLegal fulfills industry-leading security and compliance standards. Materials for the Demonstration.
Students should realize the necessity of making and recording accurate measurements in the chart provided. Ask students: - I combined a liquid and a solid, and you saw bubbling, which is made from gas. Why do you think this reaction is similar to the reaction of vinegar and baking soda? Remind students that 10 mL of vinegar and ½ teaspoon of baking soda caused the foam to overflow. Overall, the lab itself took anywhere from 20-30 minutes to set up and execute. Remind students that in the last lesson, they learned that in a chemical reaction, certain atoms in the reactant molecules unbond from one another and then rearrange and rebond in different ways to form the products. Your data supports the hypothesis that the sodium bicarbonate decomposed to sodium oxide. How many of each type of atom is on the product side of the equation? Asking questions and defining problems in grades 9–12 builds from grades K–8 experiences and progresses to formulating, refining, and evaluating empirically testable questions and design problems using models and simulations. For good results, these test tubes must be clean and completely dry before you start. White foam will rise up in the graduated cylinder and overflow as the tablet becomes smaller and smaller. They can graphically analyze this discrepant event by plotting the change in pressure vs. the mass of sodium bicarbonate and viewing all 5 of the data runs. 1) Their lack of prior knowledge makes all four options appear plausible. This gas was not in one of the reactants, so it must have been produced during the chemical reaction.
This made for good conversation regarding experimental error. Place about 2 teaspoons of baking soda in a small cup for each group. They will make the connection between the written chemical equation, the molecular model, and the real substances in the reaction. Question to Investigate. Holding the test tube by the clamp, move the test tube slowly back and forth through the flame. Students will be able to count the number of atoms on the reactant side and on the product side of a chemical equation. 5) Student-driven experimental design. Consumable: Solid NaHCO3. As a teacher, my favorite scenario was when different groups would have different conclusions and, consequently, different chemical reactions proposed. Students saw that the same type and number of atoms were in the reactants as were in the products.
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. Graduated cylinder (100 mL). I did not tell them how long to heat their sample or what to look for when determining if the reaction is complete. As novices, they have no idea how to confidently predict the products of such a reaction. Their task: Figure out which balanced chemical equation accurately represents the decomposition of sodium bicarbonate. 1 clear plastic cup. The use of stoichiometry to generate sufficient evidence that will support their eventual conclusion will be the meat of their argument. Even though I could have given them a brief explanation as to why something like this would not decompose in this manner, I did not need to since it is not even offered as a potential equation—away with bicarbonate! Based on the graphs, the third trial is closest to an ideal ratio of reactants. 4) Developing an argument from evidence. However, since each reaction appears equally plausible from the perspective of the student, this meant the evidence gathered was the primary driver behind the construction of their argument. I realize you're probably worried about being marked down on your lab report because you came to the "wrong" conclusion.
All new trials should be conducted this same way. Students need to experience the fact that science is not just a linear process driven by knowing exactly what to do and exactly what to expect every step of the way without hiccups. Questions that challenge the premise(s) of an argument, the interpretation of a data set, or the suitability of a design. Materials for Each Group. Maybe there is another reaction that also happens, perhaps involving the air, or the crucible, or the gas from the bunsen burner. Continue to move the entire test tube slowly through the flame until only a white solid remains. These are the number of that particular atom in the acetic acid molecule. Mathematical and computational thinking at the 9–12 level builds on K–8 and progresses to using algebraic thinking and analysis, a range of linear and nonlinear functions including trigonometric functions, exponentials and logarithms, and computational tools for statistical analysis to analyze, represent, and model data. Gently agitate the test tube after each addition of HCl. It could be that this is due to an error you made... or maybe the stupid sodium bicarbonate didn't get the memo that, according to the teacher (or the text or Wikipedia or whatever), it was supposed to decompose to sodium carbonate, so it just went ahead and decomposed all the way to sodium oxide.
The appearance of condensation in the dry test tube is a sign that there is still some water left in your sample test tube. Maybe your starting sodium bicarbonate contained water (so it wasn't 100% pure) and that water was driven off in the heating. Some groups only recorded the mass of their sodium bicarbonate, without considering the mass of their test tube and glass stir rod. Lay each empty test tube flat on the balance pan. In this lab, students will conduct a chemical reaction that will be used to launch a rocket. In this demonstration, students will observe that the vapor of an extinguished candle flame is ignitable.
Continue adding HCl slowly until all of the solid has dissolved. 2) Application of stoichiometry. There are various choices for receiving the doc.
