Surpassed in hardness only by diamond, it is sometimes known commercially as carborundum. Silicon carbide is used primarily as an abrasive for sandpaper and is manufactured by heating common sand (silicon dioxide, SiO2) with carbon in a furnace. SiO2 (s) + C(s) + CO(g) + SiC(s) What mass of silicon carbide should result when 4.3 kg of pure sand is heated with an excess of carbon?

1. A sample of feldspar weighing 1.500g is decomposed, and eventually there is obtained a mixture of KCI and NaCi weighing 0.1801 g. These chlorides are dissolved in H20, a 50-mL pipetful of 0.08333 N AGNO3 is added, and the precipitate is filtered off. The filtrate requires 16.47 mL of 0.100ON KCNS, with ferric alum as indicator. Calculate the percentage of K20 in the silicate.

Carl records In his lab notebook the powder In a test tube, the powder melts into a silvery liquld that welghs less than the original powder. that when he heats a red Antolne develops a idea that most substances will chemnically combine with an invisible gas in the atmosphere he calls oxygen. Antoine uses hls ideas to explain burning as the comblnation of a substance with oxygen, and reduction (e.g. durlng che formation of iron from iron ore) as the splitting of a substance from a chemical combination with oxygen. for chemical reactions based around the ohn analyzes all the known compounds of carbon and oxygen. He finds nd writes down a that says the ratio of masses of carbon that combine with 100 g of oxygen in these compounds are always in whole umber ratios (e.g. 2:1 or 3:1).
