Chemical and Biological Weapons are Your FriendsAs we go on our daily lives‚ terrorists are buying and developing dangerous and hazardous biological and chemical weapons to obliterate us. They do not care who they harm; their mission is to cause terror‚ to spread chaos‚ to engulf the world in anarchy. They want to know that they are making people terminally ill and sick. They will be enjoying a job well done while your skin is covered with excruciating painful blisters‚ or while you tell your loved

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.

Introduction‚ aim and hypothesis Chemical reactions are accompanied by the release or absorption of energy. Reactions which release energy are described as exothermic and those which absorb energy are endothermic. The energy released in chemical reactions was previously stored as chemical potential energy in the reactants; this stored energy is called enthalpy. The aim of this practical is to observe and classify chemical processes as endothermic or exothermic‚ based on the changes in temperature

I was assigned was the element Manganese. The symbol for manganese is Mn. It is number 25 on the periodic table. That means it has 25 protons and electrons even on mars or anywhere you go it will have the same protons and electrons. The atomic number would also be 25. It has 30 neutrons also in in the nucleus. The melting point for Manganese would be 1519 K (1246°C or 2275°F). The boiling point would be 1519 K (1246°C or 2275°F) according to http://education.jlab.org/. It also could be 1245.0 °C

If a chemical reaction occurred‚ write a balanced equation for it. Then using the A‚ B symbols‚ write a general equation for a single-displacement reaction. Here are the chemical formulas of the reactants for each reaction: • zinc – Zn copper sulfate – CuSO4 • aluminum – Al copper sulfate – CuSO4 • zinc
