Do not worry that you find these problems difficult; many students consider them to be the toughest problems in the course. In general, you just have to keep thinking about where the energy comes from and where it goes. For example, if a hot object is dropped in a calorimeter, it will cool down. Thus, it loses energy...

Many students have a difficult time understanding significant figures. It is a very important concept to master so keep trying if you find it to be challenging! Here are some things to keep in mind as you go: 1. Practice. You will get plenty of practice throughout the book, but if you are having particular trouble a...
In the problem, you are told to add the numbers, so you will need to follow the rules on page 28 of the textbook for adding with significant figures. You will need to expand the number given in scientific notation before adding. Once you’ve added, you must use precision to determine where to round. When you look back...
First, I would use a scientific calculator. On that calculator, there is either an “EE” key, an “EXP” key, or a “x10^x” key. There will only be one not all three. I will assume it is “EE” because that is the most popular. This key abbreviates “times ten raised to the.” Thus, if I wanted to enter the number 1.43×10^-23 ...
We recommend algebra and biology together because biology is a freshman-level course, and algebra marks the spot at which a student is at a freshman level when it comes to science and math. If your student is READY for algebra, he or she is, most likely, ready for biology. Taking biology and algebra together ensures t...
Significant figures rules are only used for measurements, not constants. You should not have to worry about the number of digits for constants and neither should that affect your significant digit calculations. The rules listed on pages 21-25 of the Chemistry textbook state that they are for measurements only. ...

In the first part of this example, you have: (405 nm/1) x (10-9 m/1nm) When you multiply 405 by 10-9, you get 405 x 10-9 This is not standard scientific notation, because there is no decimal place in 405. To get it into scientific notation, move the decimal to the left 2 places. This decreases 405 by a factor of 10...
