(a)What is a displacement reaction? Give one example. (b) Why metals are used in ringing bells
Answers
Answer:
a Notice that there are sometimes colour changes during displacement reactions, depending on the reactants and the products involved. ... Some other 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.
b Metals are used in making bells because they are sonorous that is they produce a ringing sound when we strike them. Because they are sonorous ie they make sound. There are other objects meant to vibrate in abell-like way that are not made of metal. ... Because of sonority ,they produce sound when striking on hard surfaces.
Answer:
A)A displacement reaction is the one wherein the atom or a set of atoms is displaced by another atom in a molecule. For instance, when iron is added to a copper sulphate solution, it displaces the copper metal. A + B-C → A-C + B. The above equation exists when A is more reactive than B.
