53. When balanced with whole integers, the reaction of isopropyl alcohol (C3H8O) with oxygen to form carbon dioxide and water (and a bunch of heat!), the carbon dioxide would have ___ for its coefficient.

                a. 1                         b. 3                         c. 6                        d. 8                         e. 9

54. What is the coefficient of oxygen when this reaction of solid maltose (C12H22O11) at room temp and pressure is balanced with whole numbers?

       ___ C12H22O11 + __ O2                       à __ CO2 + __ H2O

                a. 1                         b. 6                         c. 11       d. 12       e. 22

Answer 1

51.

    2AgBr(s) ----------> 2Ag(s) + Br2(l)

b. the coefficient of the silver product is (s).

52.d. a decomposition and an oxidation-reduction reaction.

silver is reduced and bromine is oxidised.

53. 2C3H8O + 9O2 ------------>6Co2 + 8H2O

c.6

54.   C12H22O11 +12O2                      ---------> 12 CO2 + 11H2O

d.12
