Explanation / Answer
32. When the following reaction is balanced what is the coefficient for -OH?
____N2H4 + ____ClO3- + ____-OH ------> ____NO3- + ____Cl- + ____H2O
3 N2H4 + 7 ClO3- + 6 OH- ----> 6 NO3- + 7 Cl- + 9 H2O
A) OH- = 6
33. What species is the reducing agent for the reaction above?
a. N2H4 b. ClO3- c. –OH d. NO3- e. Cl-
Reducing agent = a. N2H4
34. When the following reaction is balanced what is the coefficient for NaCl?
____NaClO3 + ____H2O + ____I2 ____H+ + ____IO3- + ____NaCl
5 NaClO3 + 3 H2O + 3 I2 ----> 6 H+ + 6 IO3- + 5 NaCl
A) NaCl = 5
35. What species is the oxidizing agent for the reaction above?
a. NaClO3 b. H2O c. I2 d. IO3- e. NaCl
A) oxidizing agent = NaClO3
