here we go, for those who wanted to get started on chem early. listed are some sites that should help. take the time to browse them all and find what works best for you and your prof.....some sites are basic chem and some more advanced. please feel free to add something i might have missed to help us along the way.
thankyou to all on allnurses that contributed these sites.

how to write a science paper
Have a question to anyone out there who is studying scientific notation right now. How do you know how many numbers to leave after the decimal point in the nonexpoental term. For example how do you know if 144 in scientific notation is 1.4 x 10 2 or 1.44 x 10 2 (please pretend the 2s are superscript)?Thanks in advance.
Assuming 144 is your answer, you would leave as many significant figures as the equation allowed. If the maximum number of allowable sig figs is 2, then your answer is 1.4 x 10^2. If it's 3, then your answer is 1.44 x 10^2.
Example: 2.0 x 72.0 = 1.4 x 10^2 (can only have 2 sig figs because 2.0 has 2 sig figs, and that sets the maximum sig figs your answer can have.)
But
14.4 x 10.0 = 1.44 x 10^2 (can leave the 3rd sig fig because both terms on the lefthand side of the equation have 3 sig figs.)
So, we just completed our first lab in which we dealt with metric system measurements. Everything was pretty straight-forward. However, I'm trying to finish up the postlab assignment, and the first 2 questions are confusing me even more as I'm trying to search for the correct answers. 1)"State the metric system reference standard for the following quantities: a)mass b)length c)volume." 2) "State the metric system basic unit for each..." Are these the same? If not what is the difference? I'm confused.
My professor has posted chapter specific test questions along with answers on our yahoo groups page. If anyone is interested in practice questions, I have them available. Know how to publish them on this forum? (They're .doc format)
phoenix, are they copyrighted (i.e., do they come from the text publisher)? If so, they would be removed by an Allnurses staff member because we are not able to post copyrighted information, per the Allnurses Terms of Service.
ok guys, I'm starting today. I am surprised that I'm not panicing yet. I'm actually glad to be starting, the anticpation is killing me. We also found out today that our company just got swallowed by a bigger company, so after Jan 1st we might see some layoffs. I am actually more motivated to do well and get into a nursing program.

You know, I didn't think of that. Unfortunately, they are copyrighted.
Had my first day of chemistry last night. There are 20 students, 17 are applying to the nursing school. (yikes) By the end of the night 2 students had to drop. Anywho, the teacher seems like a nice guy, he doesn't do the best explaining in the world so I'm glad I had read the chapter already. Otherwise I would have been sooo lost. Lab was fun, measurements, and safety.
Our grade is based on our labs and quizzes. No homework grades, but no midterm or final, and the lowest quiz grade is dropped.
So far so good.
I'm pretty excited about my online class. It is going to be a whole lot of work. I spent all of yesterday evening just trying to get through all the orientation materials. I'll start on Ch. 1 tonight. The teacher seems to be experienced with teaching online classes, and there are opportunities for workshops in person.
I think I'll be fine as long as I keep up with everything. Of course, it requires total self-discipline to take it on-line. I think I'm mature enough to handle that. I certainly couldn't have back when I was 18.
The majority of the students in my class are pre-nursing. I think that is true of most of the "Introduction to Chemistry" classes. It's kind of scary how many pre-nursing students are out there. It makes you wonder if there really is going to still be a nursing shortage 10 years from now.
I go to my first lab tonight.

I would think that the basic unit of mass is grams, length is meters and volume is liters. As far as the reference standard goes, I have never really heard of that term but maybe it refers to the English or Customary System which is used in the United States?? Mass could be pounds, length would be feet and volume would be quarts or gallons????
By the way, thanks to those who provided the feedback to my question.

I hear you, I'm glad I read the chapters before I go to class otherwise what my teacher is saying would really confuse me. I think it frusterates my other classmates who don't come to class having read first.
Good Luck!

generally you use the amount of significant figures in the origional problem, so if it is 144 the answer would be 1.44, but you would have to ask your teacher to make sure what they prefer.
