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

comes from the chemical pinene. There are two compounds in a pine tree‚ Alpha-pinene and beta-pinene. The chemical compounds The pinene is part of the terpenes family‚ which are produced by plants. Terpenes can form aerosols with other chemicals that go into the clouds and cool the air‚ as well as make the skyline above mountains blue. The terpene pinene is also a reason that pine trees are so flammable since pinene contains sixteen hydrogens and ten carbons‚ which causes easy burning. This a reason that

What is it? Dysprosium is a silver-white chemical element discovered in 1886 by a French scientist named Paul-Émile Lecoq de Boisbaudran. It wasn’t isolated until a different separation technique (ion-exchange) developed in the 1950s by a Canadian scientist Frank Spedding and his team. This rare element it is never naturally found. It is only made chemically. It can be found in minerals such as xenotime. Dysprosium is a member to the lanthanide family on the periodic table just like all the other

However‚ this time‚ instead of being struck by a bomb‚ they were struck by a chemical warfare agent (CWA) known as sulfur mustard‚ which destroyed their home‚ murdered their newborn child‚ and resulted in weeks of intense medical care. The use of chemical weapons during World War One revolutionized chemical warfare. Since WW1‚ chemical weapons have grown in popularity.
