Balance the following equations by ion electron method: Cr_(2)O_(7)^(2-) + C_(2)H_(4)O+H^(o+) rarr 2Cr^(3+) + C_(2)H_(4)O_(2) + H_(2)O

The inversion of cane sugar is represented by: C_12 H_22O_11 + H_2O to C_6H_12O_6 + C_6H_12O_6 It is a reaction of :

The oxidation states of Cr in [Cr(H_(2)O)_(6)]Cl_(3). ,[Cr(C_(6)H_(6))_(2)] and K_(2)[Cr(CN)_(2)(O)_2(O_2)(NH_(3))] respectively are

In the reaction of Mohr's salt [FeSO_4(NH_4)_2SO_4.6H_2O] with oxalate ions in the presence of H_2O_2 and H^(o+) ions, [Fe(C_2O_4)_3]^(3-) ion is formed. Calculate the minimum mass of Mohr's salt and K_2C_2O_4 required to prepare 10 g of K_3Fe(C_2O_4)_2 .

A compound 'A' formula of C_(3)H_(6)Cl_(2) on reaction with alkali can give 'B' of formula C_(3)H_(6)O or 'C' of formula C_(3)H_(4). 'B' on oxidation gave a compound of the formula C_(3)H_(6)O_(2).'C' with dilute H_(2)SO_(4) containing Hg^(2+) ion gave 'D' of formula C_(3)H_(6)O which with bromine and alkali gave the sodium salt of C_(2)H_(4)O_(2) . Then 'A' is

The inversion of cane sugar is represented by C_(12)H_(22)O_(11) + H_(2)O rarr C_(6)H_(12)O_(6) + C_(6)H_(12)O_(6) It is a reaction of

Which of the following is pseudo first order reaction? I. CH_(3)COOC_(2)H_(5)+H_(2)O overset(H^(+)) rarr CH_(3)COOH +C_(2)H_(5)OH II. C_(12)H_(22)O_(11)+H_(2)O overset(H^(+)) rarr C_(6) H_(12)O_(6) +C_(6)H_(12)O_(6)
