CP Questions For Endoexothermic Reaction Lab - Revised 2021

ChemistryWiki | RecentChanges | Preferences

Answer the following questions in a clear and concise manner.

1a) What was the chemical name, chemical formula, color and phase of one of the reactant?

1b) What was the chemical name, chemical formula, color and phase of the other reactant?

2) Was what you performed in this lab a physical (base particles did not rearrange) or a chemical change (base particles did rearrange)?

3) Was what you performed in this lab exothermic or endothermic? What observation did you use to come to your conclusion? If you watched video of lab (thru Edpuzzle), what observation did that provide to come to you conclusion.
4) If a chemical reaction did occur, list the ones (from the 4 observations of a chemical reaction notes) you obsered.

5) List any other observations you made when the reaction occurred (during or after).

6) Draw the potential energy diagram for this reaction. Label/show the following:

7) After our post lab discussion, answer the following: Did all the reactants react in the lab or was there some unreacted reactant left after the chemical reaction stopped? How do you know or how do you don't know? Explain.
8) After our post lab discussion, Write the chemical reaction for this lab including phase (don't need to balance it).

9) After our post lab discussion, two "things" about this reaction is uncommon for most reactions.
