Question

what happens in a displacement reaction?
(a) Aluminium oxide
(b) Zinc acetate
Give one example of a displacement reaction.
Balance the following equation:
CaCl, + H2O
Ca(OH), + HCI
Something To Do​

Answer 1

Answer:

Displacement reactions occur when a metal from the electrochemical series is mixed with the ions of a metal lower down in the electrochemical series. The atoms of the more reactive metal push their electrons on to ions of the less reactive metal. An example can be seen below.

Explanation:

examples of displacement reactions which can occur are: zinc displacing iron ions from iron(II) sulfate solution. nickel displacing copper from copper(II) nitrate solution. copper displacing silver from silver(I) nitrate solution.

Answer 2

Answer:

displacement reaction 2 reaction in which a strong reactant replace a weak reactant is called displacement reaction in first part zinc replace aluminium because zinc is more reactive than aluminium

CACL+H20-----> CAOH+HCL

Ca(OH) + HCL ----> Cacl+H20

Explanation:

there is no chance for first reaction because chlorine is much reactive than iron OH ion
