Answer:
A. An Atom
Explanation:
An atom is the smallest particle of an element, having the same chemical properties as the bulk element.
Number 2 lower entropy and higher entropy
Explanation:
When solid cadmium sulfide reacts with an aqueous solution of sulfuric acid then the reaction will be as follows.
Hence, ionic equation for this reaction is as follows.
Therefore, net ionic equation for this reaction is as follows.
The included angle, i.e. If two pairs of sides of two triangles are in proportion, and the included angles are equal, then the triangles are similar.
