8. Based on the observations above, does a chemical reaction take place When you MIx thnese substances? Yes. Because it turns to liquid. the temperature goes down. Also the smell changes. a. Which of these observations would you use to serve as data to support your claim? b. Do you think a process like this could be used as energy for moving a car? 9. Please insert the class consensus model of a car engine at the particle level. OXygen 一

Answer Question 8 → Do you think this was a chemical reaction and what observations support your idea? What does that mean about energy transfer? → Do you think a reaction like this could power a car? → Did this raise any questions for you? → If we were to model this process using our LOL diagrams what might that look like? → It seems like a chemical reaction due to the presence of a new gos (evidence: the very bad smell that wasn't there before) → The mixture looked like it chonged, we think we hove a liquid that wasn't present before. → Both the barium hydroxide and ammonium chloride storted out ot room temperature, but the surroundings got really cold - moybe the reaction is getting energy transferred to it from the environment. → We are starting to think that temperature change in ony direction can be an indication of a chemical reaction → Maybe if we can apply o reaction to our model we con figure out if it can make our cor go.
