Soluble | Phosphate PO 3-4Carbonate CO 2-3Sulfite‚ SO 2-3 | H | Soluble | Once you recorded all of the data‚ there were a few questions that needed to be answered. A. Compare your results with the solubility rules and/or solubility table in your chemistry text. I would say that my results turned out pretty close to the rules in the text book. I observed many different reactions occurring. The colors of the solutions changed from clear to purple‚ from clear to blue and yellow‚ and from clear to a milky

If you add one teaspoon of sugar to iced tea‚ you get an unsaturated solution. If you keep

celebration to mark specialoccasions. The thrill and excitement generated by fireworks‚brightening the night sky and immersing it with vivid displays ofcolour and technicality‚ which makes them a crowd pleaser. Behind all the excitement of fireworks‚ chemistry plays an importantrole in creating the vivid colours we witness lighting up the sky. Theactual chemical reactions that take place in the explosions requirethe use of oxidisers‚ reducing agents and binders. The additions ofvarying metal chlorides

Chemistry Notes Cracking: * 2 types of Cracking; Catalytic cracking and Steam/thermal cracking. * Catalytic cracking‚ using a catalyst called Zeolite (Aluminosilicate)‚ 500 degrees C‚ in the absence of air and at pressures just above atmospheric * Thermal cracking is done without a catalyst; steam is passed through very hot metal tubes at 700-1000 degrees C at just above atmospheric pressure. * This is used to break down longer chains of unsalable hydrocarbons into smaller salable

1. LIFESTYLE CHEMISTRY -many consumer products have been developed because of increased understanding of chemical substances‚ chemical reactions & the biochemistry of human body surfaces -some products are used as cleaning agents while others have been developed to act as barriers against environmental factors like wind and heat -some products are mixtures‚ used for medicinal purposes‚ & require a different understanding of body chemistry & chemical interaction -production of these

Calculate the percentage recovery of products. Test for purity and identification of products. Abstract Cyclohexene and cyclohexanol are both colourless aromatic compounds. The major difference between the two is the presence

Solutions Solutions are a combination of solvents and solutes. When a solute dissolves into a solvent‚ the combined product of the two reactants is called a solution. The definition of a solute is the reactant that’s being dissolved. The only difference from a solute and a solvent is that the solvent is the one that’s doing the dissolving. Molecules randomly flow in all directions until there is an equal concentration throughout the solution. The dissolving process can vary depending

1.1 Chemistry A. What Is Chemistry? * Because living and non-living things are made of matter‚ chemistry affects all aspects of life and most natural events. * Matter- is anything that has mass and occupies space. * Chemistry- is the study of the composition of matter and the changes that matter undergoes. B. Areas of Study * Five traditional areas of study are organic chemistry‚ inorganic chemistry‚ biochemistry‚ analytical chemistry‚ and physical chemistry. * Organic
