BRICJ A Brick is a block‚ or a single unit of a ceramic material used in masonry construction. Typically bricks are stacked together‚ or laid as brickwork using various kinds ofmortar to hold the bricks together and make a permanent structure. Bricks are typically produced in common or standard sizes in bulk quantities. They have been regarded as one of the longest lasting and strongest building materials used throughout history. In the general sense‚ a "brick" is a standard-sized weight-bearing

Pepcid AC: Racing to the OTC Market Introduction and Background In the late 1980’s and early 1990’s‚ the pharmaceutical industry began to experience a decline in sales. Many companies began to see the potential of the over-the-counter (“OTC”) market as a proactive and defensive strategy to counteract the generic threat and to reinvigorate market share growth from their existing product line. In 1989‚ Johnson & Johnson and Merck (“JJM”) joined forces in an effort to bolster both company’s

Enthalpy of Neutralization J. Smith M. Smith CHEM 1290-xx 10-31-06 TA Purpose: The purpose of the experiment is to determine the calorimeter constant for the calorimeter holding a specific solution based on the data of heat lost and heat gained. The purpose is to also be able to determine the enthalpy of neutralization for the reaction of a strong acid (phosphoric acid) and a strong base (sodium hydroxide). Experimental: Materials: The materials needed for this lab included; 2 large beakers‚

INTRODUCTION Given appropriate chemicals and equipment‚ the specific heat capacity and molar mass of a metal‚ enthalpy of neutralization of an acid and base‚ and the enthalpy of solution of an unknown salt can be determined by following specific procedures. All of these procedures require the use of a calorimeter‚ which are of two types: a bomb calorimeter and a coffee cup calorimeter. Calorimeters are simply devices used to measure the amount of heat gained or lost in a system. Although this

Chapter 1 Chemical Reactions and Equations Q.1. Why should magnesium ribbon be cleaned before burning in air ? Ans: Magnesium ribbon is a very reactive metal. When stored it reacts with oxygen to form a layer of magnesium oxide on its surface. This layer of magnesium oxide being a stable compound prevents further reaction of magnesium with oxygen. The magnesium is cleaned before burning in air to remove this layer so that the metal can be exposed to air properly. Q.2. Write the balanced
