### Re: Midterm

I believe everything we have covered in class up until that point will be on the midterm.

### Re: Homework

I believe so yes. He says five problems from any of the sections he's provided are appropriate. Doing the other problems on our time is probably preferred by him but I think any five problems from the same section is definitely okay. It also might depend on your TA, so I would ask to see if they rea...

### Re: Determining the state of matter

I don't believe it's always possible to be able to determine the states of matter if they aren't given to you in the problem. If the problem states that all elements or compounds are at "normal temperature and pressure" you could maybe infer what the state of matter is from what you know a...

### Re: Class example

Because in reality, that value cannot be negative. Therefore, in order to obtain the correct answer we used it as a positive.

### Re: m/s^-1

The unit for speed of light is ms^-1 (m*s^-1) or m/s. The -1 is used when you write the unit the first way because the 's' is in the denominator.

### Re: Reactant vs. Reagent

They are used interchangeably but to my understanding, typically a reactant is what you refer to in a balanced chemical equation and a reagent is a term used in the lab. I think we use reagent more because we deal with chemistry connected to biology and learn more through biological examples. Using ...

### Re: States of Matter in a Chemical Equation[ENDORSED]

Yes. It's important in future calculations and it's always good practice to begin doing it when it isn't necessary.
