Define physical and chemical properties, provide three examplesof each, discuss their reversibility, and explain the fundamentaldifferences between them. 7:30TAMEmeve mant inwateumoleenle andthusiti polan innatuu :11. When someone is injured, responding medical personnel may useeither hot packs or cold packs to treat the injuries. These areexamples of miniature chemical reactions. Using hot packs and coldpacks as anexample, explain the terms endothermic reaction andexothermic reaction.12. Combustion reactions take place between a fuel and oxygen andproduce carbon dioxide and water. Balance the followingcombustion reaction.OC2H,O + D02OCO2 +DH2013. Aqueous lead (II) nitrate, Pb(NO;)2 undergoes a doubledisplacement reaction with aqueous sodium chloride, NaCl, inwhich a precipitate forms. If the precipitate contains lead, write thebalanced chemical equation forthis reaction. Be sure to include thestates of each of the reactants and products.14. Explain the four basic types of chemical reactions. Be sure to includea sample equation for each type. Describe how rate relationships andactivation energy are important in chemical reactions.15. Write the equilibrium expression for the following reaction. Basedupon the value of K, would you expect there to be more or lessproduct in the equilibrium mixture? Why?CaO(s) +CHa(g) +2H20(g)CacOa(s) +4H2(g)Kp = 2344
