Parallax Lab Problem Part 2
Lines of Sight
Now that you have found d algebraically in terms of b1, b2 and x,
lets see how to go about calculating d practice values. Lets say
b1 = 29.5 cm
b2 = 27.4 cm
x = 69.3 cm

AP TOPIC: Colligative Properties
Colligative properties are those that depend only upon the number of solute particles present in a solution, and not their nature.
A non-electrolyte solution is one where the solute particles do
Light and Time Problems
1. Everything you see is in the past, because you are seeing things the way they looked when light left them. In
effect, you are trapped in your own little time bubble. Ordinarily this isnt a problem because the speed of light is
Molarity & Concentrations Honors Chemistry Notes
Solution - a homogeneous mixture. Could be a liquid, gas, or solid
Solute - the stuff that gets dissolved. Could be a liquid, gas, or solid
