It contains 2‚3‚5-T acids‚ 2‚4-D acids‚ and TCDDs‚ which are carcinogenic chemicals that cause cancer‚ birth defects‚ miscarriages‚ and skin diseases. 2½ million U.S. soldiers were exposed by the Agent Orange during the Vietnamese War. These veterans suffered from various types of cancer. In Vietnam‚ the Agent Orange led to 1.5 million birth

reaction occur simultaneously side by side. A reduction reaction occurs only if an oxidation reaction occurs and vise-versa. Electrons are given in oxidation while in reduction electrons are gained. Oxidizing agent is a chemical substance which has a large tendency to gain electrons‚ while reducing agent is a chemical substance causes other substances to be reduced and itself oxidized. Procedure: For this lab was used metals and substances provided in the lab oxidation-reduction pack‚ and some extra materials

Down Group 7‚ the shared electrons are further from the nucleus and more shielded. There is a weaker attraction for the bonding electrons down the Group 2) Trends in chemical properties of the elements • The Group 7 elements are oxidising agents which gain an electron when they react • The ability to oxidise decreases down Group 7 • This can be shown by halogen displacement reactions where elements higher up the group will displace elements further down the group • This can

Results and Discussion Potassium permanganate‚ KMnO4‚ is widely used as an oxidizing agent in volumetric analysis. In acid solution‚ MnO4- ion undergoes reduction to Mn2+ ion as shown in the equation: 8 H+(aq) + MnO4-(aq) + 5e- → Mn2+(aq) + 4 H2O(l). Since the MnO4- ion is violet and the Mn2+ ion is nearly colorless‚ the end point in titrations using MnO4- as the titrant can be taken as the first permanent pink color that appears in the solution being titrated.1 The number of moles of potassium
