11. When someone is injured, responding medical personnel may use
either hot packs or cold packs to treat the injuries. 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. Balance the following
combustion reaction.
OC2H,O + D02
OCO2 +DH20
13. Aqueous lead (II) nitrate, Pb(NO;)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. Describe how 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 there to be more or less
product in the equilibrium mixture? Why?
CaO(s) +
CHa(g) +
2H20(g)
CacOa(s) +
