We no longer use atoms of the same elements are identical in size, mass and properties.
Answer:- d. London dispersion
Explanations:- Carbon dioxide structure is given below:
O=C=O
It has two polar C=O bonds but even then it is non polar molecule as it's linear and the dipole moment of one C=O bond is canceled by it's opposite C=O bond.
being non polar, the only attraction forces present in it are London dispersion forces.
(i) Assume that CuSO₄ + H₂O was the reaction that happened in that dish. Copper sulfate is anhydrous, so if water is added, it becomes copper sulfate pentahydrate.
CuSO₄(s) + H₂O(l) = CuSO₄ · 5H₂O(s)
Copper sulfate is soluble in water, so copper and sulfate both become aqueous. Copper sulfate has become crystallized, and the water has become attached to it.
(ii) As seen in my equation of (i), all that is left in the dish is a solidified, blue crystallized version which has a octahedral molecular geometry.

Electromagnet is a type of magnet which is produced by passing electric current through a magnetic material such as iron. Here electric energy is converted to magnetic energy. The magnetic material is coiled with wire through which electric current is passed. Increasing the number of coils and increasing the strength of the current increases the strength of the electromagnet. However, the electromagnet loses its magnetic properties when the current flow is switched off.
(Answer) (1) Increase the number of coils and increase the strength of the current.
Answer:
Copper and silver should work.
