Chemical engineers today face a major dilemma when it comes to deciding what should hold paramount‚ economic gain or moral statute? Many practicing engineers are faced with problems that result from the consequences of their engineering decisions. Engineers have to realize the importance of proper engineering decisions and how one should act when faced with a problem such as deciding what comes first safety or economic gain. When faced with such a problem‚ engineers often employ the risk-benefit

Chemical Warfare Final Draft Do you think it’s right to use chemical toxins to harm or kill people who are defending‚ or fighting for their lives? I don’t and that is why I am aganist chemical warfare. There are other ways which can be used to defend your country without taking away the lives of many people in such a barbaric fashion. Chemical warfare takels many innocent lives even when they haven’t done anything wrong! Chemical warfare is a way of torturing people with nerve‚ blister‚ and choking

Observations of Chemical Changes Purpose: The purpose of this experiment is to observe chemical changes in common consumer products to determine if the chemicals are basic‚ acidic‚ or remain neutral when mixed with other chemicals. Procedure: In this experiment‚ various chemicals were mixed together‚ to determine a reaction. Using two drops from chemical 1 and two drops of chemical two‚ unless otherwise stated‚ then recording the type of physical reaction or color changes that occurred.

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

The Inhumane Weapons of Warfare Chemical warfare is a barbaric weapon of war that should be banned from any war situation. Chemical Warfare is using any chemical or chemical mix that can physically or mentally harm a human being. It has been killing people for over 2600 years and was created by Spartans. “They grabbed burning sulfur pitch and threw it over the walls of Athens attempting to fill the city with toxic gas.”[6] They tried this because they had a small army that was trying to take over
