Tiles are especial things created by man to protect our house’s parts such as roofs‚ floors‚ walls‚ etc. Because it is useful to man‚ tiles lessen faster than ever since our population grows faster. Most of the Filipinos caught sick. This is because dirt‚ bacteria‚ or maybe harmful insects such as cockroaches‚ usually attracted to none tiles areas that usually in kitchen of poor homes. Poor families are incapable to buy cheaper tiles or incapable to buy enough tiles in order to protect their house’s

Experiment 1: Mechanism of Nitrile Oxide and Alkene Cycloaddition 1. Purpose: to clarify the mechanism for the cycloaddition reaction between benzonitrile oxide and an alkene‚ and to test the regiochemistry of the reaction between benzonitrile oxide and styrene. 2. Plan: Each student in a group of three will work to create a reaction with the Benzonitrile Oxide with‚ cis-stilbene‚ trans-stilbene‚ or styrene in an Erlenmyer flask. With this Reaction solution thin layer chromatography will be

FDA suggested that there are 400 types of lipsticks on the market contains lead. Lead is proved to be a toxic and when a pregnant woman ingests the lipstick by accident‚ the lead consumed can be passed onto the infant and might cause mental retardation to the infant.

metal was named according to place where it was found‚ the Cyprus islands. Copper produced in massive stars and spread in the world as minerals like chalcocite and chalcopyrite (sulfide of copper)‚ azurite and malachite (carbonate of copper)‚ cuprite (oxide of copper). The atomic number of copper is 29 and the atomic mass is 63.546‚ which means that mentioned element has 29 electrons‚ 29 protons and 34 neutrons. Moreover‚ it has 29 isotopes. Some of them are resistant and other are radioactive. Copper
