Re: How do we tell if it is acidic?
You have to look at the ions. The conjugate acids of a strong base and the conjugate base of a strong acid both do not affect the pH. The conjugate base of a weak acid (anion) is basic, and vice versa for the conjugate acid of a weak base.

Re: Molarity and Dilution of a Solution
As volume increases, the molarity will decrease and vice versa for when volume is decreased. However, the number of moles will stay the same.

I believe they are during your discussion section for weeks 4 and 7, so I'm assuming everyone is taking it at different times.

Re: Mass Percent Converted to Grams
Hi! It just makes it easier to think about in terms of 100g, especially after calculating the mass percent composition.

Re: rounding during equations
I would assume we should round based off of significant figures. Here is a link from the website about the rules for significant figures https://lavelle.chem.ucla.edu/wp-conten ... OUT_SF.pdf

Re: Experiments of electrons
In the photoelectric experiment, electrons behave as particles because when the light intensity was increased, the electrons were not emitted. I'm not sure about the experiment regarding wave properties.

Re: Structure of Lectures
On myucla, it says that the lectures are online-recorded, so the lectures are pre-recorded and asynchronous.

Re: Accuracy vs Precision
I agree! The target example was really helpful in explaining that precision is more about consistency where accuracy is about correctness.
