What’s the answer for number 9 9. Draw the Lewis structure for sulfur tetrafluoride, SF4, and then draw the electron pair geometry. What's thename of the molecular shape of sulfur tetrafluoride? Note: You can draw this on paper, take a picture, andpaste the picture in your document.10. Draw the structure of water. Is water considered polar or nonpolar? Why? Note: You can draw this on paper,take a picture, and paste the picture in your document.11. When someone is injured, responding medical personnel may use either hot packs or cold packs to treat theinjuries. These are examples of miniature chemical reactions. Using hot packs and cold packs as anexample,explain the terms endothermic reaction and exothermic reaction.12. Combustion reactions take place between a fuel and oxygen and produce carbon dioxide and water. Balancethe following combustion reaction.OC2H60 + D02 →OCO2 + OH2O13. Aqueous lead (II) nitrate, Pb(NO3)2 undergoes a double displacement reaction with aqueous sodium chloride,NaCl, in which a precipitate forms. If the precipitate contains lead, write the balanced chemical equation forthis reaction. Be sure to include the states of each of the reactants and products.14. Explain the four basic types of chemical reactions. Be sure to include a sample equation for each type. Describehow rate relationships and activation energy are important in chemical reactions.15. Write the equilibrium expression for the following reaction. Based upon the value of K, would you expect thereto be more or less product in the equilibrium mixture? Why?CaO(s) + CH4(g) + 2H2O(g)CaCO3(s)+ 4H2(g)Kp = 2344 Periodic Table of the ElementsVIAkenicnter 94-PuНе1314NA151617VIAIIAIIAVAVIAName PkeAamic DLi BeCNNea tter lrAS LD SSetcategaryinthe meal-mtal talen oler afedgordladBeyAlkai netaaAlirerhra ActinidesMetalaidactieta adteantwiol praperties14Tstan resPetranstenrt ktia gassNa MgAl Si PSCI Ar1210VIID11VIDVIIVIIVIDIB34292KKCa Sc Ti VCr Mn Fe Co Ni Cu Zn Ga Ge As Se Br KrTanH37424445$2Rb Sr YZr Nb Mo Tc Ru Rh Pd Ag Cd In Sn Sb TeXe:1277Cs BaHf Ta W Re Os IrPtAu Hg TI Pb Bi Po At Rn17104108110T6Fr RaRf Db: Sg Bh Hs Mt Ds Rg Cn Nh Fl Mc Lv Ts OgCe Pr Nd Pm Sm Eu Gd Tb Dy Ho Er Tm Yb LuMertionAc Th Pa u Np Pu Am bm Bk CI És im Md No Lr100Np Pu Am Cm Bk Cf Es Fm Md No LrTherismare1.
