Mini-Report: How Do Scientists Report Data? “Determination of the Empirical Formula of an Unknown Lead Oxide” By: Dr. C. Steven Joiner In this paper‚ they walk through and explain the process known as smelting. The experiment demonstrates the historical process known as smelting and could theoretically be used to determine the empirical formula of other metal oxides found in nature. This paper explains how the process of smelting and how metals can be extracted from their ores. This is because

then fuse them in the melting pot of 130O-140OnC‚ and finally cool them into solid soluble glass. Considering the differences of alkali metal oxide‚ soluble glass can be divided into sodium silicate and potassium silicate‚ and sodium silicate is often used. Among the components of sodium silicate (Na2O*nSiO2)‚ the ratio of silicon oxide molecules to sodium oxide molecules is known as the module of soluble glass‚ generally between 1.5 to 3.5. And the number of module decides the properties and performance

The main and major air pollutants found in most city areas are carbon monoxide‚ nitrogen oxides‚ sulfur oxides‚ hydrocarbons‚ and particulate matter‚ liquid or solid form. These pollutants are isolated throughout the world’s atmosphere in areas high enough to increasingly cause serious health risks. Serious health problems can take place rapidly when

40 – 60 % propene is used for the manufacture of 2-propanol. A large number of catalysts for 2-propanol dehydrogenation have been studied‚ including copper‚ zinc‚ and lead metals‚ as well as metal oxides‚ e.g.‚ zinc oxide‚ copper oxide‚ chromium-activated copper oxide‚ manganese oxide‚ and magnesium oxide.
