这随便找本普化看都有表格
: 4. Balance the reaction below in acidic solution
: IO3- + I → I2
: What volume of 0.352M HCL is needed to produce 2.48*10^-3
: moles of iodine , I2, with an excess of KIO3 and KI?
: (a)2.48ml (b)4.96ml (c)7.05ml (d)14.1ml (e)none of these
: 5. Which of the following relations is correct?
: (a)H=E-PV (b)H=G-TS (c)for a irreversible change dS2 < dq/T
H=E+PV G=H-TS dS2 > dq/T
: (d)for a reversible change dS1=dH(sys)
dS1=dH/T
: (e)for and irrversible change △S1 + △S2 = 0
△S1 + △S2 > 0
: (f)at the phase transition △S1 = △H/T
: ※ S1 = S(sys) S2 = S(surr)
: 6. Oxygen gas. generated by the reaction2KClO3(S) → 2KCl(S)+3O2(g).
: is collected over water at 27 C in a 2.00-l. vessel at a total
: pressure of 760. torr.(The vapor pressure of H2O at 27 C is 26.0torr.)
: How many moles of KClO3 were consumed in the reaction ?
: (a)0.0790moles (b)0.119moles (c)0.0527moles
: (d)0.0813moles (e)none of these
