Question

when nickel(ii) nitrate is poured over copper strips, which of the following occurs? partial activity series k ca mg al zn fe ni pb h cu ag f₂ cl₂ br₂ i₂ solid nickel precipitates. no reaction occurs. the nitrate ion becomes no₂. nickel and copper combine to form a new compound.

Explanation:

To determine the reaction, we use the activity series. A metal can displace another metal from its compound only if it is more reactive (higher in the series). Here, nickel (Ni) is higher than copper (Cu) in the activity series. So, copper (Cu) is less reactive than nickel (Ni). Therefore, copper cannot displace nickel from nickel(II) nitrate. Thus, no reaction occurs.

Answer:

B. No reaction occurs.
