Observations of Chemical Changes Purpose: The purpose of this experiment is to predict and examine chemical changes/reactions among common chemicals found in consumer products at a macroscopic level. Procedure: The procedure of this experiment was to carefully mix different chemicals together using the chemical filled pipettes and the 96-well plate and determining what chemical reactions occurred.

BIOL 140 Lab—The Chemical Composition of Cells Name ____________________________ I) Introduction All cells contain four major types of macromolecules: carbohydrates‚ lipids‚ nucleic acids‚ and proteins. In today’s lab‚ we will be studying three of the four-proteins‚ carbohydrates and lipids. Various chemical tests can be used to detect the presence of each of these molecules. Most of the tests involve a color change visible to the eye. If a color change is observed‚ the test is considered positive

2014 Lab report #1 on chemical and physical properties/ changes Introduction Summary: The purpose of this experiment is to allow students to understand how to differentiate physical and chemical properties and reactions of matter by observing changes of matters under circumstances. Physical properties are properties of matter that can be observed without changing the composition of the matter‚ including the volume‚ mass‚ color‚ density‚ and shape of it. Chemical properties include the matter’s

Gonzales Mrs. Krametbauer English III 10 November 2014 Why Chemical Engineering? Individuals take engineering as something distance to their lives due to rigorous courses to get through. As some would say that it is not worth it‚ other clever individuals have figured this out. To be a chemical engineer‚ an individual explores and takes on other sciences to create important products to better peoples lives. As Mark and Sherri Devaney stated‚ “…Chemical Engineers are charged primarily with finding ways to

1 Class X: Maths Chapter 2: Polynomials Top Concepts: 1. The graph of a polynomial p(x) of degree n can intersects or touch the x axis at atmost n points. 2. 3. 4. A polynomial of degree n has at most n distinct real zeroes. The zero of the polynomial p(x) satisfies the equation p(x) = 0. For any linear polynomial ax + b‚ zero of the polynomial will be given by the expression (-b/a). 5. The number of real zeros of the polynomial is the number of times its graph touches or intersects x axis. 6. 7

PRICE RANGE OF PRODUCTS Above is the price range of all Apple products between the years of 1975 to present. Steve Jobs manufactured products that were not just far advanced than other products in the same category‚ but they were also out of reach for most consumers. When Apple Computer launch its Apple II in 1977‚ it cost $1‚298 and if you wanted a more powerful version it would cost you a twice that amount. In 1984‚ Apple Computer released the Macintosh at a price of $2‚495. At these prices
