Question: I am struggling with these mathematic conversions bc my instructor hardly lectured on it at all. I spent time trying to fgure them all out myself etc. and im not a quiter. My question is: Is this normal? and will I be ok if i dont know some of thebeginning metric conversions. I mean i can memorize the elements etc. and what certan things are. Give me some advice thanks!

First. Chemistry is like a foreign language. And just like any other foreign language, you need to learn some basics and then practice to become fluent in it. One of the basics is the math. It is called "factor label method" or "dimensional analysis" to chemists. Yes, it will seem strange at first but it's important that you understand this. It will make simple problems trivial and complicated problems simple. You must learn this method and practice it. It's the difference between A/B and CDF students. In high school, I struggled with conversions via the proportion method and often made mistakes. When I went to college, my first instructor on the first day of my first chemistry class told us all "forget proportions. Use factor label method or else". the or else was ZERO points given. It's that important. Spend the time and learn the method. So... let's make sure you understand what's going on. read my explanation here. It'll take about 10-15 minutes. http://answers.yahoo.com/question/index;... now let me give you some more examples http://answers.yahoo.com/question/index;... notice I started with the "given" on the left and converted to the right? notice everything in ( ) is a "unit factor" = 1? notice how I strung along multiple "unit factors"? notice the ³ in (100cm / 1m)³? rule 5 on that first link here's a more complicated problem. http://answers.yahoo.com/question/index;... Ignore the problem. But do look at the math. Can you see where I used "factor label method"? can you identify the "unit factors"? another example. This time read the problem. Does it look difficult? Now look at how I solved it http://answers.yahoo.com/question/index;_ylt=AjjM4giFqm7Ws8fZRrIP65fty6IX;_ylv=3?qid=20100825173025AAUsa47&show=7#profile-info-t7pckqOMaa another problem that looks difficult on the surface. Look for "factor label method" and "dimensional analysis" http://answers.yahoo.com/question/index;_ylt=AklAXUqZpl3g0Z6mkzBCexPty6IX;_ylv=3?qid=20100825183626AAqsvS0&show=7#profile-info-sLipRj8Saa and another http://answers.yahoo.com/question/index;_ylt=AlNsVf28tR0I6g.B_HLpeRjty6IX;_ylv=3?qid=20100824204335AAAyAxa&show=7#profile-info-4L4MERg7aa and another... http://answers.yahoo.com/question/index;_ylt=AvYLLVL5jXQO6TazBdNZBPvty6IX;_ylv=3?qid=20100824210848AASBcIt&show=7#profile-info-ti4WStRAaa look at how complicated the other answers were. This problem took me longer to push "preview" and "submit" than to actually type the answer. and this one. http://answers.yahoo.com/question/index;_ylt=AviE.mccfdJzsWR0CMJSwSXty6IX;_ylv=3?qid=20100824070145AA8DTEp&show=7#profile-info-ne7MQDIRaa notice how I embedded the conversions into the equation? here's another. http://answers.yahoo.com/question/index;_ylt=Apf4RKkRvk6FZT28fZFZglDty6IX;_ylv=3?qid=20100301143353AApWguA notice where I used "factor label method"?.. steps 2,4,5? notice how I used the coefficients of the balanced equation as a "unit factor"? and this one. http://answers.yahoo.com/question/index;_ylt=Ak3kxT4coEVcR97lJpGqxUTty6IX;_ylv=3?qid=20091206104543AA5xiuL see that first equation? notice it looks like a giant factor label equation?. This is more along the lines of dimensional analysis. More advanced. Let's call it "intermediate level". And the way to solve this problem is to look at the dimensions and manipulate them via factor label method to get the answer you need. ******** questions?

Hello there. You can do lots of different things to gain customers. Ask your friends and family for referrals and give them a discount if they bring you a new customer. Go to businesses and drop off books for the employees and if it is a place with a waiting room, as if you can leave some books there. Take books to laundrymats and leave a bunch there. Keep books on you and give them out when you are running errands. I always give a book to the bank teller, grocery store cashier, fast food cashier, etc. You can have parties if you want to but you don't have to. I have not done parties and I do really well with my business. Also have you signed up for the E-Rep site? then you can promote your business online as well and sell anytime and anywhere. Contact your upline and your district manager as well as they may be able to help you out too! Don't get frustrated and just make a plan that wil work for you. good luck!

avon is a very tough thing to sell cause the only way to sell it is to have partys, and sooner ot later you will run out of family and friends and your client base stops. you need to get a different product or service that you can do nation wide

If you are referring to General Chemistry II, then yes it is normal to struggle a little bit. It's not the easiest class in the world. All you will really need to memorize are your equations, constants and units of those constants. Metric conversions can be carried out online and all but you will only be successful at this if you do practice problems. Afterall, practice does make perfect! Do all of your homework and understand the principle and you will do fine! Don't be ashamed to buy a complete idiot's guide to chemistry...this is the best and most easily understood source of information outside of the classroom and textbook!

Brier Originally Answered: Just started working and need some advice with my 401k?
401k can be daunting at first. I've been working for awhile, and still don't know what quite to do. Matching funds are always a good thing. Be sure you contribute at least enough to your 401k to get the maximum from this. In your case, this means you want to contribute at least 4% from each paycheck. There are basically two types of funds offered in a 401k - mutual funds and bonds. Mutual funds are a collection of stocks based on some sort of theme. It could be "Europe" or "small companies" or even something as arbitrary as "Companies starting with the letter 'D'" - read the prospectus and other documentation to try and evaluate if a fund sounds like a good investment. Because mutual funds are tied directly to the stock market they are riskier than bonds, but generally have better returns. Bonds are like loans made to the government (state or federal) that are then repaid over several years. They are a lot less risky than stocks/mutual funds, but also have a lot lower rate of return. Many experts say that your mix of mutual funds (stocks) to bonds should change as you get older. When you're young and just starting out, an 80-20 mix is considered good. As you get older, you'll want to shift from stocks to bonds, to better protect your nest egg. By the time you're ready for retirement, your mix should be closer to 10-90. If you really don't know which funds to invest in, there's always the index fund, which is based on the S&P 500. Then there are "package deals" (the FID DRDM INDX xxxx" funds) which are based on your estimated year of retirement. So if you were looking to retire in 2040, choose the 2040 fund. If you leave your money in this fund, over time you'll see its prospectus shift from mostly stocks to mostly bonds. Finally, remember that you are not guaranteed to make money. If the stock market takes a hit, or a specific company has problems, you may lose money in one or more of your investments. The mutual funds try to protect investors against this by having multiple stocks in their portfolio, but it's still a good idea to check in on your investments every 3 or 6 months. If a fund isn't doing well, it may be time to move your money into a different one. However don't obsess over it. The market is going to "wobble" from day to day, so don't panic if you see it go up one day, and go back down the next. You're more interested in the longer term trend, and so long as that's going upwards, you should do OK.

Matching $ for $ is the greatest deal you can find. It translates into free money given to you by the company. Beyond $$ that would not be matched, these $$ could go into a ROTH ira. ROTH=you invest with money that already has been taxed before you receive your monthly income. Never will you be taxed again for this investment or its capital gains. On the other hand, if the extra money ($$ not matched by your employer) is invested in a tradtitional ira, you pay taxes on that invested money plus on any capital gains when you withdraw money from that account (earliest is age 59+1/2 and latest is 70+1/2). ROTH's earliest withdrawel is 59+1/2 also, but you are not required to ever take it out. There is so much more I could tell you about the differences between the two, but I suggest you type "Explain Traditional IRA vs. ROTH IRA" in your online search engine. You'll get plenty of education this way. As for Stocks and Bonds: Remember that no investment ever is a sure, guaranteed thing. EVER! But what is suggested is that the younger you are, the more investments risk you can take. Your investments go up and down, always. When stock prices fall, you get to buy more stocks for the same amount of money than if stock prices were high. It's like this: you have $10 to invest in apples. If the apple sells for $1, you get to buy 10 apples. If the apple sells for $2.50, you only get 4. So, actually, the worse the market is doing, the better for the buyer and the worse for the seller. However, as long as you don't sell your shares, you have lost nothing. Final advice. Go with a minimum of bonds in the fund you choose, and add more percentage of bonds as you get older. As young as you are, concentrate on stock funds.
