(There should b Previous AnswersAll attempts used; correct answer displayedTo draw the Lewis structure from a molecular formula, we need to find the sum of the valence electrons. Sulfur and oxygen are in group 6A (16) and contribute six electrons per atom. Therefore, the total number of electrons isvalence electrons in SO2 = (electrons contributed by S) + (electrons contributed by O) = (1 × 6) + (2 x 6) = 18 electronsThere are many ways to arrange atoms, but not all configurations will form a valid structure. We can begin drawing the structure by placing the first element in the middle and connecting the rest of the atoms to it through single bonds. This willsuffice for all binary compounds and for many others that do not begin with hydrogen (as hydrogen can only form one single bond and cannot be a central atom). This will give a structure with sulfur in the middle attached to two oxygens Fromhere we can complete the octet of each atom by forming a double bond between sulfur and one of the oxygens, and leaving the rest of the electrons as nonbonding This means that one oxygen will be attached through a single bond and havethree pairs of nonbonding electrons, whereas the other will be attached through a double bond and have only two pairs of nonbonding electrons. The sulfur, meanwhile, will have one pair of nonbonding electrons. This completes the octet foreach atom but leaves several with different formal charges. The formal charge can be calculated using the following formula:Formal charge = valence electrons – (bonding electrons) – nonbonding electronsPlugging in these values for the single-bonded oxygen, we getFormal charge of Single – Bonded Oxygen = 6 – 5(2) – 6 = –1Plugging in these values for the double-bonded oxygen, we getFormal charge of Double – Bonded Oxygen = 6 – (4) – 4 = 0And plugging in these values for the sulfur, we getFormal charge of Sulfur6 – (6) – 2 = +1

The element carbon undergoes many inorganic reactions, as well as being the basis for the field of organic chemistry. Write balanced chemical equations for the reactions of carbon described below. l type='a'> Carbon burns in an excess of oxygen (for example. in the air) to produce carbon dioxide. If the supply of oxygen is limited, carbon will still burn but will produce carbon monoxide rather than carbon dioxide. molten lithium metal is treated with carbon, lithium car bide, Li2C2 , is produced. i>Iron(II) oxide reacts with carbon above temperatures of about 700 °C to produce carbon monoxide gas and molten elemental iron. i>Carbon reacts with fluorine gas at high temperatures to make carbon tetrafluoride.
. To obtain useful electrical energy from an oxidation-reduction process, we must set up the reaction in such a way that the Oxidation half-reaction and the reduction half-reaction are physically one _____another.
The iron content of hemoglobin is determined by destroying the hemoglobin molecule and producing small water-soluble ions and molecules. The iron in the aqueous solution is reduced to iron(II) ion and then titrated against potassium permanganate. In the titration, iron(ll) is oxidized to iron(III) and permanganate is reduced to manganese(II) ion. A 5.00-g sample of hemoglobin requires 32.3 mL of a 0.002100 M solution of potassium permanganate. The reaction with permanganate ion is MnO4(aq)+8H+(aq)+5Fe2+(aq)Mn2+(aq)+5Fe3+(aq)+4H2O What is the mass percent of iron in hemoglobin?
One of the few industrial-scale processes that produce organic compounds electrochemically is used by the Monsanto Company to produce1,4-dicyanobutane. The reduction reaction is 2CH2CHCH+2H++2eNC(CH2)4CN The NC(CH2)4CN is then chemically reduced using hydrogen gas to H2N(CH2)6NH2, which is used in the production of nylon. What current must be used to produce 150.kg NC(CH2)4CN per hour?
In theory, most metals should easily corrode in air. Why? A group of metals called the noble metals are relatively difficult to corrode in air. Some noble metals include gold, platinum, and silver. Reference Table 17-1 to come up with a possible reason why the noble metals are relatively difficult to corrode.
