Chemistry of Fireworks The sights and sounds of each explosion are the result of several chemical reactions – oxidations and reductions – taking place within the firework as it ascends into the sky. Oxidizers produce the oxygen gas required to burn the mixture of reducing agents and to excite the atoms of the light-emitting compounds. Various oxidizers are used in both the black powder and the stars. The most commonly used oxidizers are nitrates‚ chlorates‚ and perchlorates

(D) What do these ingredients do in the mixture? When tested as a whole can be considered an eye irritant. Complex Sodium Phosphates and sodium carbonate are used as a water softener. Nonionic surfactant and chlorine bleach is a cleaning and water spot preventive agent. Sodium silicate is a dishwasher and china protection agent.

Dr. GEORGE ROMBO Cholera This is an infection of the small intestine caused by bacterium vibrio cholera. Transmission is mostly from the fecal contamination of food and water that is caused by poor sanitation Susceptibility About 100 million bacteria must typically be ingested to cause cholera in a normal healthy adult. Children are also more susceptible with 2- 4 year old having the highest rates of infection Individual susceptibility to cholera is also affected by their blood type with

agents‚ scouring powders‚ and toilet bowl cleaners. The most common oxidizing agent in bleaches is sodium hypochlorite‚ NaClO (sometimes written NaOCl). Commercial bleaches are created by bubbling chlorine gas into a sodium hydroxide solution (remember this from your “funky redox rxns”?). Some of the chlorine is oxidized to the hypochlorite ion‚ ClO- and some is reduced to the chloride ion‚ Cl- (a disproportionation reaction). The solution remains strongly basic. The chemical equation for the process

products‚ such as bleaches and hair coloring agents‚ contain oxidizing agents. The most common oxidizing agent in bleaches is sodium hypochlorite‚ NaClO (sometimes written NaOCl). Commercial bleaches are made by bubbling chlorine gas into a sodium hydroxide solution. Some of the chlorine is oxidized to the hypochlorite ion‚ ClO-‚ and some is reduced to the chloride ion‚ Cl-. The solution remains strongly basic. The chemical equation for the process is: Cl2(g) + 2 OH-(aq) ( ClO-(aq) + Cl-(aq)

(b) Cl- ion (c) When the stress (Chlorine from hydrochloric acid and calcium chloride) is added on the reactant side (more reactants)‚ the pink color reduces and blue color increases. In other words‚ CoCl42- is favored to compensate for the change or minimize the stress. 4. A. Adding

Higher Chemistry Mole Calculations Moles and Number 1 mole of any substance contains the same number of atoms/molecules/ions as there are atoms in a 12g sample of carbon -12 12g of carbon-12 contains a constant number of atoms. This number is known as the Avogadro constant (L) and is equal to 6.02 x 1023. 1 mole of carbon-12 contains 6.02 x 1023 atoms. Therefore‚ 1 mole of any substance contains 6.02 x 1023 atoms/molecules/ions. For example‚ 1 mole of aluminium contains

Juliana Amenta 2/18/13 Mr. Zastrow Chemical Warfare During World War 1 The first World War has been reported to be one of the most brutal wars in the history of time for many reasons. One of those reasons was strategic usage of chemical warfare. Chemical gas was used on both sides of the line‚ which turned out to be fatal for many. World War I was mostly fought in the trenches‚ where soldiers lived in deep‚ v-shaped holes or underground bunkers. Both sides would occupy these trenches in order
