Observation of Chemical Changes Purpose In this experiment‚ the student studied the composition of materials in a setting where the indications of chemical changes were safely observed. The changes observed consisted of bubble formation‚ colors‚ viscosity‚ and precipitate formation. Procedure Using a well plate: use a different well for each chemical combination. Two drops (unless otherwise noted) of each chemical in the combinations (below) should be placed in one well. A dark and light

Mole Ratio of a Chemical Reaction: Copper & Silver Nitrate Lab #4 OBJECTIVE In this experiment‚ you will determine the number of moles of reactants and products present in the reaction of copper and silver nitrate‚ and calculate their mole-to-mole ratio. The mole-to-mole ratio relating to the disappearance of copper and the formation of silver metal will be used to write the balanced equation for the reaction. The reaction of copper metal with silver nitrate solution is a single

Introduction: The chemical industry has become one of the largest manufacturing industries in the world since the beginning of the 21st century (Murmann‚ 2003). They convert raw materials such as oil‚ natural gas‚ air‚ water‚ metals‚ and minerals into more than 70‚000 synthetic chemicals (United States Department of Commerce‚ n.d.). Heavy demands on chemicals allowed prosperity of materials goods and had brought convenience for many people. Now they can be found everywhere around world‚ and even

development has been the idea of chemical weapons‚ especially those in the form of weaponized gasses. These weapons‚ which are defined as an “ammunition or device‚ specifically designed to cause death or other harm through toxic properties of toxic chemicals.” have the potential to cause an unprecedented amount of harm if their proliferation is not regulated. The presence of these weapons throughout history is all too familiar to many of the world’s nations. Early chemical weapons‚ such as Chlorine and
