Web(c) Sulfur forms the compound carbon disulfide, CS 2 . (i) Draw a dot-and-cross diagram for carbon disulfide. Only the outer electrons need be shown. Use a dot (·) for the electrons from carbon and a cross (×) for the electrons from sulfur. (2) (ii) Deduce the value of the S-C-S bond angle in CS 2. Justify your answer. (3) Angle Web1 day ago · SF6 or sulfur hexafluoride is an inorganic and one of the most stable gases that are known in chemistry. This gas has more density than air. The general identification of the gas can’t be done because it is odorless and colorless in nature. There is also no taste of the gas as such. SF6 is noncombustible and nonflammable in nature.

Web3 hours ago · The sulfur trioxide is a tetra atomic chemical molecule where both the sulfur and three oxygen molecules bond with an equal number of valence electrons. The diagram is drawn showing dots of valence electrons around the symbol of both sulfur and oxygen atoms with lines predicting bond formation. WebBoth Sulfur and oxygen atoms are located at VIA group in the periodic table. So, oxygen and sulfur atoms have six electrons in their valence shell. Total valence electrons given by two sulfur atoms = 6 * 2 = 12 There are three oxygen atoms in S 2 O 32- ion, Therefore, Total valence electrons given by oxygen atoms = 6 *3 = 18 in which province is cape town
