Lab #5: Refraction of Light Theory: Refraction can be defined as the bending of a wave when it enters a medium which causes it to have some reduced speed. In terms of light‚ refraction occurs when the ray passes through some medium which slows its speed; such as water or glass. In this instance the ray tends to bend towards the normal of the medium. The amount of bending or refraction which occurs can be calculated using Snell’s Law (). Objective: To measure the index of refraction of Lucite

Catherin Escobar 1. What is liver mortis? How might this reveal information about the time of death? Liver Mortis is the settling of blood in the lowest parts of the body after death. This process usually begins 8 to 12 hours after death and can help investigators tell if the body has been moved. 2.What three aspects does a forensic autopsy seek information about? Describe each of these aspects? Cause of death- medical problem that leads to death. Mechanism of death- any weapon or instrument

Ranking Salt Solutions by pH 6-2: Ranking Salt Solutions by pH In this assignment you will be asked to rank aqueous solutions of acids‚ bases‚ and salts in order of increasing pH. This is most easily done by first identifying the strong acids that have the lowest pH‚ the strong bases that have the highest pH‚ and the neutral solutions that have a pH near 7. The weak acids will have a pH between 1 and 6 and the weak bases between 8 and 14. The exact order of weak acids and

Verify that ABCD is a trapezoid. SOLUTION: First graph the points on a coordinate grid and draw the trapezoid. SOLUTION: The trapezoid ABCD is an isosceles trapezoid. So‚ each pair of base angles is congruent. Therefore‚ ANSWER: 101 2. WT‚ if ZX = 20 and TY = 15 SOLUTION: The trapezoid WXYZ is an isosceles trapezoid

Chromosome 6 Robin Cook’s book Chromosome 6 is about organ transplantation and the possible dangers that could arise if the organs became tradable commodity‚ but before reading the book we had no idea what it was going to be about. Biotechnology was not a subject us two girls knew a lot about. Hearing the word biotechnology we thought of cloning‚ lab work‚ and experiments. Little did we know that it is much more complex than we thought. Biotechnology deals with crops to animals‚ fruit‚ milk‚ and
