CMIS 102 Homework 2 Problem Analysis In order to calculate the total price to purchase all the components required to build a state-of-the-art gaming computer‚ state-of-the-art must be defined. For the purposes of this program design‚ state-of-the-art is defined as a set of computer components that are capable of operating current games to a satisfactory level. A sample of minimum and recommended hardware requirements for modern games was taken and a baseline established for components that

Experiment 5 COMMON ION EFFECT MALUBAY‚ Justin Damian PADRILLAN‚ Hazel Rose CD2‚ Group 5 Ms. Sarah Sibug 6 April 2013 ------------------------------------------------- ------------------------------------------------- I. ABSTRACT The common ion effect occurs when a given ion is added to an equilibrium mixture that already contains that ion‚ and the position of equilibrium shifts away from forming more of it. This paper is a follow-up of the experiment which aims to determine the common-ion effect

ELECTRONIC STRUCTURE OF ATOMS -arrangement of atoms’ electrons -the number of electrons in an atom -distribution of electrons around the nucleus and their energies • ATOMS *Billiard Ball Model (JOHN DALTON) *Plum Pudding Model (JOSEPH J. THOMPSON) *RUTHERFORD’s Model of Atom -atoms are tiny‚ hard‚ indivisible spheres -electrons (negative charge) occupy the atom - Atom is mostly empty space with a dense nucleus • PROBLEMS with Rutherford’s Model

Acidic vs. Alkaline Introduction: Potential of hydrogen‚ or pH‚ is a scale used to express the acidity or alkalinity of a solution. The scale ranges from 0 to 14‚ below seven represents acidity‚ seven is neutral‚ and more than seven is basic. Acid-base indicators show whether the solution is acidic or alkaline. They do this by reacting with the solution‚ seen as a color change‚ as the concentration of hydrogen (H+) or hydroxide (OH-) ions changes in an aqueous solution. Different indicators

Vanden Eynden CHM2510 AU13 Practice Midterm Exam #2 CHM2510 Practice Midterm Exam #2 This exam is designed to give you a small glimpse as to the format of the exams I write. The content of the exam has no direct correlation to the difficulty of the actual exam you will take. Use this exam as another problem set so you can get a little more practice in where multiple chapters are combined into one document. It would greatly benefit you to try doing this exam first WITHOUT ANY NOTES
