2. Please complete the take home portion of the test (question 1 – part 2) that you pulled from your folder today.
This is a combustion analysis question with precipitation analysis to determine the empirical formula of the compound. I am reposting the worksheets and the coorresponding videos that we have previously used if you need to review. Do not forget it is not what you do first but what you do last!
Lecture 0a below reviews combustion analysis.
Lecture 1.2 below reviews combustion analysis with precipitation analysis
Your take home question has combustion analysis and precipitation analysis combined.We completed these questions in week 8!
AP Lecture 0a : Calculating chemical formulas from Combustion analysis (that are obtained through labs).
This video review question 3 of the Analytical Chemistry I KEY- determining chemical formulas.pdf
Make New Video for Combustion analysis for next year for multiple samples.
b) Lecture 1.2 : Precipitation analysis
This video reviews these worksheets you should focus on the last 2 questions of side 2:
