Chemical Equilibrium: Le Chatelier Principle By Sarah Ramos and Kristina Todorovic Chemistry 203 DEN Dr. Mohamed El-Maazawi Part A. Acid-Base Indicators Purpose In this part of the experiment‚ we will find a reagent that will shift the acid-base equilibrium reaction described by Equation (2) in one direction and then a second reagent that will cause the equilibrium position to shift back in the opposite direction. Introduction An acid–base indicator

My Solar System Name Period Introduction: Every physics student has had a lot of experience with the force of gravity. Unfortunately‚ this experience is limited to the interaction between a very large object‚ the Earth‚ and much smaller objects that are very close to it. This is a very limited range of the possibilities. Software simulations of gravity allow physics students to explore a variety of other gravitational interactions between objects. These activities are designed to be used

A magic square is an arrangement of the numbers from 1 to n2 in an n x n matrix‚ with each number occurring exactly once‚ and such that the sum of the entries of any row‚ any column‚ or any main diagonal is the same (Alejandre)‚ called the magic constant or sum. The magic sum can be found using the formula (n(n2 + 1))/2 for any n x n matrix. There are many different variations of magic squares‚ of which‚ some have more ways of finding the magic sum in the square and others use geometric shapes or

Three years ago‚ the eagle was 7 times as old as the falcon. Find the present age of each bird. Solution x = falcon’s age now 4x = eagle’s age now {the eagle is 4 times as old as falcon} x - 3 = falcon’s age 3 years ago 4x - 3 = eagle’s age 3 years ago 4x – 3 = 7(x – 3) {three years ago‚ eagle
