What is the color of bromcresol green indicator in a solution with a pH value of 2.0?
Solution: An indicator allows us to figure out the pH range of the solution and whether it is acidic or basic. To do this problem, we need to look at Table M of the Regent Reference Table, Common Acid–Base Indicators.
According to the table, bromcresol green, has a pH range for co...
To check which bond is most polar, you must first find an electronegativity table (easily found by googling). You will then identify 2 atoms that make the bond, and find their electronegativity difference. Whoever has the highest electronegativity difference, is most polar.
Ex: Which bond is most polar H-Cl or C-Br?
Answer: H-Cl because it's electronegativity different is 3-2.1=0.9 which is great then that for C-Br (2.8-2...
I graduated from NYU in 2010 with Honors in Chemistry and Psychology. My first encounter with chemistry was somewhat tough. Having never taken AP Chemistry at my high school, I found the few beginning weeks to be hard. However, as the time went on I learned exactly how to study for this class and ace it.
Most of the students at NYU will take Chemistry with Professor Halpin, who is a very sweet and caring professor. He...
First, I would say that the two most important qualities a tutor must have are true care for the student and passion for the subject taught. Everything else is a matter of practice and experience.
What is the goal of tutoring? It’s not to simply share knowledge (that’s what professors do during lectures), and not show how to solve problems (even though it is a part of the session), but rather to make sure that the stu...
