zinc is more reactive than iron and copper

B

iron is more reactive than zinc and copper

C

Three conductivity cells A, B and C containing solutions of zinc sulphate, silver nitrate and copper sulphate respectively are connected in series. A steady current of 1.5 amperes is passed through them until 1.45 g of silver is deposited at the cathode of cell B. How long did the current flow ? What mass of copper and what mass of zinc got deposited in their respective cells ? (Atomic mass : Zn = 65.4 u, Ag = 108 u, Cu = 63.5 u)

Three beakers labelles as A, B and C each containing 25 mL of water were taken. A small amount of NaOH, anhydrous CuSO_4 and NaCl were added to the breakers A, B and C respectively. It was observed that there was an increase in the temperature of the solutions containers in beaker A, and B, where in case of beaker C, the temperature of the solution falls. Which one of the following statements(s) is(are) correct? (i) In beaker A and B, exothermic process has occured. (ii)In beaker A and B, endothermic process has occured. (iii) In beaker C exothermic process as occured. (iv) In beaker C endothermic process has occured.

A chemistry lab-incharge kept zinc metal in FeSO_4 solution and observed that after sometime, green ferrous sulphate soluton turns to colourless and some brown powder is depostied on zinc. In the above reaction, zinc metal acts as

Two beakers of capcatity 500 mL were taken one of these beakers labelled as "A" was filled with 400 mL water whereas the beaker labelled "B" was filled with 400 mL of 2 M solution of NaCl.
