Name: Keziah V. Cuyom Section: 9 - Malaya Topic: Types of Chemical Reaction A chemical reaction is a process that is usually characterized by a chemical change in which the starting materials (reactants) are different from the products. Chemical reactions tend to involve the motion of electrons‚ leading to the formation and breaking of chemical bonds. There are several different types of chemical reactions and more than one way of classifying them. Here are some common reaction types. However‚ if

Overview Chemical Warfare is using the chemical properties of a substance to your advantage during war. This has been going on for centuries. Even the most basic forms of weapons were used. People have been putting poison on the end of their spears and arrows since they have been around. Over the years‚ it has also developed into much more advanced chemistry. In this article‚ I am going to focus on the more advanced‚ modern uses of chemical warfare in World War I and World War II. World War

Experiment 1: Observations of Chemical Changes Abstract: In the lab 1 experiment‚ the objective was to observed properties of various chemical reactions between twelve different basic compounds. Each reaction revealed chemical properties consisting of color change‚ CO2 gas formation‚ and/or precipitate formation. Certain reactions made it possible to distinguish between an acid and a base. Through the results of this experiment‚ chemical properties observed in the reactions could be used to associate

Biological and Chemical Outline Biological and chemical warfare has been around since the beginning of time. From poison tipped arrows to purposely transmitting smallpox to individuals. There has been ongoing political conflict on biological and chemical warfare for quite some time for legitimate reasons too. Biological and chemical warfare is very deadly and sometimes inhumane‚ but on the other hand it is very cost efficient and is very effective at doing its job. Biological and chemical warfare

a business has less cash to spend‚ finding that an ‘old’ offer is accepted when it was expected to have expired can be very damaging for a business. In this case from the Victorian era‚ Montefiore had made an offer to buy shares in the Ramsgate Victoria Hotel for a particular price. The offer was accepted six months after this‚ and by then‚ the value of the shares in the claimant company were worth much less. The offer had never been withdrawn‚ but Montefiore said it was too late and would not go

After reading Anne Frank: Diary of a Young Girl‚ a personal diary of a girl named Anne who lived in hiding during World War II‚ I believe Anne’s wise words: that no matter what the situation‚ every person is still good at heart‚ whether you can see it or not. My opinion on this topic was greatly influenced by reading this extremely personal memoir of Anne’s life in hiding and the people in the world around her. No matter how bad a person might seem‚ I‚ like Anne‚ believe that deep down inside‚ they
