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. Inert supports‚ such as pumice‚ may be used. CH3CH=CH2 CH3CH(OH)CH3 CH3COCH3 +H2 (3) By catalytic oxidation of Propene (Wacker-Hoechst). The process is analogous

Compound and Its Parent Elements Hypothesis The hypothesis of this experiment is magnesium oxide can be synthesized by combining (burning) the magnesium with oxygen. The chemical and physical properties of each element (magnesium‚ oxygen‚ and magnesium oxide) might be different‚ from the state‚ color‚ electrical conductivity‚ and pH. Aim This experiment was performed to synthesize magnesium oxide by direct combination of magnesium and oxygen and to compare the properties of the elements (magnesium

Not only did that help me realize the Aluminum was oxidized‚ it helped me understood that the product was the gray Copper (II) Oxide instead of the red Copper (I) Oxide. This was one of the problems that I was able to solve by careful observation and checking additional

The purpose of the blast furnace is to chemically reduce and physically convert the iron oxide in to liquid iron called “hot metal” Three substances are needed for this extraction and the combined mixture of them is called the “charge”: Haematite (iron ore): contains sand with iron oxide (Fe2O3) Limestone: calcium carbonate Coke: mainly carbon They are put

Q. 7. Ammonium salts decomposes on heating. What other property do ammonium salts have in common ? Q. 8. The following reactions are carried out : A: Nitrogen + metal → compound X B: X + water → ammonia + another compound C: Ammonia + metal oxide → metal + water + N2. (1) One metal that can be used for reaction A is magnesium. i. Write the formula of the compound X formed. ii. Write the correctly balanced equation for reaction B where X is the compound formed. iii. What property of ammonia

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

reaction produced very bright light (which may cause blindness) and some sparks (exothermic reaction took place)‚ which signified that the reaction between magnesium solid and carbon dioxide gas had been proceeding. The end result is solid magnesium oxide in the form of “white ball” and carbon solid in the form of coal. These products indicated that the coupling of the first two reactions was spontaneous with the theoretical value of ∆G= -372.2 kJ/mol. -------------------------------------------------
