World War 1 each side was always desperately looking the next way to get ahead.The first deadly chemicals were found in 1914 used by the Germans. These horrific gases had deadly side effects from extreme blistering‚ to intense coughing fits. Theses gases were as effective as a weapon could get‚ but are they humane? People died brutally immense pain because of these gasses. At the end of World War I chemical weapons had changed the face of the war and raise the death count by thousands. In August 1914

Finding the Ratio of Moles of Reactants in a Chemical Reaction Purpose: The goal of the lab is to determine the mole ratio of two reactants in a chemical reaction (AgNO3 and K2CrO4). However‚ the formulas for the products are unknown. Introduction: When determining the molar ratio of a chemical equation‚ usually the formulas of the reactants and the products are known. With that information‚ it is particularly easy to determine the ratio. However‚ since the products and the formulas for

experiment is to differentiate between a physical change and a chemical change. A physical change includes a change in the material without affecting its composition‚ such as the physical state change. However‚ a chemical change includes the change in the composition of the substance. The change in color‚ formation of a gas or a solid product‚ and the production of energy are the evidences of a chemical reaction‚ thus‚ of a chemical change.

Objective: To determine the concentration and equilibrium constant for a reaction of colored product using absorption spectroscopy‚ to create a calibration curve for determining equilibrium concentrations by applying Beer’s law and to force the completion of a reaction by applying Le Châtelier’s principle. Procedure: A diluted solution was made from the stock of 0.0025 M Fe(NO3)3 by diluting 4.0 mL to exactly 100.00 mL‚ using serological pipet and volumetric flask. The concentration of the diluted

INTRODUCTION The solubility product constant‚ Ksp‚ is the equilibrium constant for a solid substance dissolving in an aqueous solution. It represents the level at which a solute dissolves in solution. A more a substance dissolves‚ the higher the Ksp value it has. In this experiment‚ a system of a sparingly soluble
