Hi everyone,
I wonder if all of you have completed the online assessments for the following modules (We are supposed to finish these before the end of this week right...?)
Empirical and Molecular Formulas
Balancing Chemical Equations
Limiting Reactant Calculations
Molarity and Dilution of a Solution
Photoelectric Effect
Atomic Spectra and The Bohr Frequency Condition
Wave Properties of Electrons and The De Broglie Equation
Heisenberg Uncertainty Equation

I found that there is no answers after I finish the assessments, and I am very unconfident to those questions...especially for the last four (which we just learn during these two weeks) So is anyone willing to share your answers? Or, we can work together to figure out a "solution manual"!

I am willing to share my own answers, but due to the fact that I'm so unconfident with the accuracy of these answers, please don't use my answers as model. If you see any incorrect answer, I would be so thankful if you could point out, and I will fix them on these posts. Let's make our "solution manual" perfect!

Photoelectric Effect:
1. C; 2. A; 3. C; 4. D; 5. B;
6. A; 7. D; 8. D; 9. E; 10. D;
11. B; 12. C; 13. A; 14. D; 15. D;

21. C; 22. B.
