Lab 1 Prousts Law of Definite Proportions
As mentioned in lecture, Proust noticed that elements combine with each other in definite proportions.
Joseph Prousts law is a very general law in the sense that it not only applies to elements reacting to
Workshop on Waves
Familiarity with wavelengths and frequencies.
1. Look at the bright line spectrum of hydrogen through the hand-held spectroscope. Estimate
the wavelengths of the three brightest lines. If you can see the fourth, record it also.

In this lab, you will be using a simple calorimeter to determine two things: the specific heat of an
unknown metal and H for a neutralization reaction. However, before we can use our calori
We will learn to solve several types of very complicated problems this semester that involve
unit conversions. As we begin, those of you who are sharp may think the problems are very
straightforward and the technique that I provide for solving these probl
There are other ways to communicate solution concentrations.
Molarity (M) moles of solute per liter of solution.
1.68g of NaF are dissolved in water and diluted to 100 mL of total volume. What is the
molarity of the solution?

streams and lakes. They lay their eggs at the age of 4 and at a depth of 75 cm and they

The laws of chemistry, as well as the laws of nature in general, are constant and
unchanging. For example, the chemical makeup for water will ALWAYS be two
hydrogen atoms bonded to one oxygen atom, an
By now, you are familiar with the concepts of mass conservation and definite proportion. You
are also aware that these two principles allow us to predict the quantities of products formed in
