Chemical warfare, mastered by the Germans, was a savage form of fighting during World War I. This weaponry was effective in mass carnage, causing countries affected by Germany’s initial chemical attacks to begin formulating their own chemical weapons even though it went against their beliefs. Chemical warfare was revolutionary but was not an ideal weapon due to the lack of consistency and immoral brutality of the death that ensued. The Germans marked an epoch with chemical warfare during World War

Chemical Bonding Chemical bonding is responsible for the strong mutual attraction, which prevails between atoms. Atoms are the basic buildings blacks for all types of matter. Atoms are capable of joining together to form molecules, which are responsible for forming most of the objects around us. Atoms forms chemical bonds because lone atoms are extremely reactive and unstable; they form bonds to achieve stability. Our world is made up by so many different elements, and they are responsible for

more familiar with the products of different types of chemical reactions by conducting several chemical reactions and observing the changes that occurred. In addition, by performing various experiments, the observations will help in writing chemical equations, which represent the process involved in a chemical reaction. Overall, the chemical changes observed throughout can determine the products that are formed from the reactants. In chemical reactions, substances that are referred to as reactants

chosen to pursue my Masters in the field of Chemical Engineering, the field that extracts me the most and draws the best of my abilities. Children are like wet cement. Whatever falls on them makes an impression. The inspiration to choose Chemical Engineering as my profession came from my father, who himself is a Chemical Engineer. As a student, I had great interest in Maths and Allied Sciences which had also indirectly motivated me to purse Chemical Engineering as my undergraduate course.

Jack Zhou Eric Lonrenzo Chemistry section # Date Chemical Reactions Introduction: The purpose of the lab was to create and observe the 4 kinds of chemical equation, and to identify reactants and products of those reactions. The four kinds of chemical reactions are synthesis, decomposition, single-displacement and double-displacement. Materials: Bunsen burner, sparker, tongs, 5 test tubes, scoop, wooden splint, lead(II)nitrate, magnesium wire, copper(II) carbonate, hydrochloric acid, zinc, potassium

can be classified into two categories: (a) balanced chemical equations or (b) mathematical-based equations and graphs. Balanced chemical equations are traditionally used to support student understanding of the overall, complex reaction under study in the experiment or simulation. Balanced chemical equations are also used to support a mechanistic understanding of the step-by-step process of reactants turning becoming products. Here, balanced chemical equations illustrate the creation and consumption

In this lab, the study of the kinetics of a chemical reaction will be investigated. One of these reactions involved the oxidation of iodide ions by bromate ions in the presence of an acid. 6I-(aq) + BrO3-(aq) + 6H+(aq) → 3I2(aq) + Br-(aq) + 3H2O(l) The reaction rate for this is slow at room temperature. The definition of reaction rate is the rate of change in concentration of either reactants or products. It is dependent on the concentration of the reactants and on the temperature. In a rate law

the equilibrium constant KC for this reaction, KC = [FeSCN2+]/([Fe3+]•[SCN-]. Using a spectrophotometer, we are going to determine the absorbance of FeSCN2+ with different concentration measurements. Introduction: Chemical equilibrium can be determined using different methods. Chemical equilibrium exists when the rate of both sides are equal. Once equilibrium has been reached, the amounts of products and reactants are constant, but if one of the products or reactant concentration can be measured

changed color. This could have been predicted as Magnesium is towards the top of the activity series, and would not have been replaced by Fe, Cu, or Zn as all those are lower on the activity series. The activity series is a guide which helps predicts chemical reactions, as it lists which metals can replace or be replaced by other metals. Part of the reactivity series is as follows, Na>Mg>Zn>Fe>Sn>Pb>H>Cu>Ag. The higher up on the activity series, the harder it is to replace that metal and the easier it

Observe • To conduct an experiment in order to study and understand how multiple factors have an affect on chemical reactions and the rate at which these reactions are happening. Procedure 1. Nature of the Reactants • Obtain 4 small test tubes and label them while, placing them in a test tube rack. • Fill each test tube half way with 4 different acids as shown in Figure 23.3 (use safety precautions while handling acids). • Obtain a 1-cm strip of magnesium and place it within each test tube.
