Answer 1

double displacement reaction

Answer 2

Hey dear,

● Answer -
Formation of CuCr2O7 from CuSO4 is due to basic nature of CuSO4 solution.

● Explaination -
Due to acidic nature of CuSO4, K2CrO4 reacts with CuSO4 to give CuCrO4.
K2CrO4(aq) + CuSO4(aq) --> K2SO4(aq) + CuCrO4(s)

Due to basic nature of CuSO4, K2CrO4 reacts with CuSO4 to give CuCr2O7.
2K2CrO4(aq) + CuSO4(aq) --> K2SO4(aq) + CuCr2O7(s) + K2O(s)

Hope this helps you.
