Units and Dimensional Analysis

Hello, I was wondering if NextStep has content that goes over using units to answer physics problems that I might be missing? If not, where would you recommend I look to help me use this strategy when answering problems? It's covered in to some extent in the physics book, but I think it would be gre...

Net Charge

Hello, I am confused as to why some hydroxides are considered negatively charged in this problem while others are not. The question asks to identify the net charge of both molecules at pH = 7. The hydroxides on the left molecule are not negatively charged, while the hydroxides bonded to the phosphor...

Class Video Quizes and Practice Passages

As I'm going through class videos, end of chapter passages, and CR review videos I've noticed a very large trend in which material that WAS NOT covered is being tested on. I can see how this can be useful, but the extent at which this is happening is rather frustrating. Again, I can see how that can...

NS Chem QBank 2: Solutions, Acids, and Electro #16

The question is asking to identify which compound contains a weak Bronsted-Lowry base. The answer is D potassium acetate. The acetate anion is the conjugate base of the weak acid acetic acid. Don't weak acids have relatively strong conjugate bases making answer D not the correct answer? I've noticed...

Re: Chemistry Chapter 6

My question was about determining the reaction order for independent question number 7 at the end of chapter 6 in the chemistry book. You say that the reaction order is the sum of exponents, which I understand. However, you go on to say "you can indeed find by simply placing the coefficients of the ...

Re: Chemistry Chapter 6

Is it because it is an elementary reaction and we can therefore assume the coefficients relate to x and y when forming the rate law?

Chemistry Chapter 6

Independent Question #7 at the end of chapter 6 in the chemistry book says the correct answer is C by forming the rate law and "raising each reactant to its coefficient". However, on page #125 of chapter 6 it specifically says "the exponents x and y must be experimentally determined; they DO NOT cor...
