Abstract To determine the rate law with respect to bleach and blue dye‚ a series of graphic and algebraic manipulations were done on the data obtained in the kinetic trace experiment in order to determine the different components that made up the rate law. Using absorbance spectroscopy to monitor concentration over time‚ rate order of the dye was found to be 1st order through the integrated rate law and through the proportionality method; the order of the bleach was also determined to be 1st order

2.4 Galileo Galilei: Sixteenth-Century “New Scientist” 1. In your own words explain why Albert Einstein considered Galileo to be the “father of modern science” Albert Einstein considered Galileo to be the father of modern science because of how many of Galileo’s discoveries have become the basis of today’s science. 2. Why did Galileo choose to use a ramp to perform his acceleration experiment? Technology during Galileo’s time was still quite primitive. His experiment which required him to drop

Black Hole A Black hole is a place in space where the gravity is so strong that nothing can escape it pull. Cyclotron A type of particle accelerator that was created first in the 1930’s. It was made of two Dshaped cavities in a constant magnetic field. Dark Matter A form of matter that is not like ordinary

Huckleberry Finn is a static character. Throughout the realistic‚ historical fiction novel‚ The Adventures of Huckleberry Finn by Mark Twain‚ the main character Huck travels with a fugitive slave‚ Jim. Constantly‚ Huck’s internal conflict between helping a fugitive slave‚ and turning him in‚ divides him. Huck ultimately ends up helping Jim‚ but treating him as subhuman‚ and taking advantage of his companionship. Huckleberry Finn wavers in his moral ideas‚ but undergoes no development. He starts to
