Clays are one of the important natural materials‚ which have been examined for catalytic applications. Clays are characterized by a layered structure and hence they are slippery when wet. They are broadly classified as cationic or smectite type (having layer lattice structure in which two-dimensional oxyanions are separated by layers of hydrated cations) and anionic or brucite type (in which the charge on the layer and the gallery ion is reversed complimentary to smectite type). Anionic clays are

Odată cu apariţia statului a apărut şi fenomenul evaziunii fiscale.Din dorinţa omului de a evita diminuarea averii sau a banilor câştigaţi au luat naştere diferitele forme de sustragere de la plata impozitelor‚contribuţiilor şi taxelor datorate statului. Fenomenul evaziunii fiscale este prezent în toate statele lumii cunoscând o creştere alarmantă.Cu toate că o eliminare completă a acestui fenomen este practic imposibilă se încearcă limitarea lui de către puterile publice.În legatură cu acest

Purpose: The purpose of this experiment is to: determine the limiting reactant of a chemical reaction that involves iron filings and a copper sulfate solution. Second‚ to determine the mole ratios between iron and copper and to show that a single replacement reaction occurs when iron and copper sulfate react with each other. And lastly‚ to determine/calculate the percent yield to better analyze the chemical reaction between iron and copper sulfate to produce copper and iron sulfate. The method
