Answer:
b, H2O(s) r H2O(g)
Explanation:
entropy is heat, so increase in heat would mean water gets evaporated or melted, or both in this case. so the only choice above that showed increase in heat is from solid(ice) to gas(water vaper) due to increase in heat in the reaction.
1. According to Rutherford and soddy's law of Beta emission:
3. According to Rutherford and soddy's law of Alpha emission:
4. The process in which two or more light nuclei are combined to form a single nucleus with the release of tremendous amount of energy is called a nuclear fusion. The inner core of Sun is at very high temperature and is suitable for fusion. In fact the source of energy of Sun and other stars is nuclear fusion reactions.
Answer:
The Lewis structure to this question can be described as follows:
Explanation:
Structure of Lewis for :
The maximum number of electrons from valence in is 8 (6 from S as well as 2 from negative change).
The valence electrons in the Lewis structure are placed on four sides of the atom.
Thus the structure of Lewis for is as follows:
Lewis Mg Structure:
Complete valence electrons are 2 in Mg.
The Lewis structure for Mg, therefore, is as follows:
The Lewis structure for
The maximum valence of electrons
in is= 0.
Thus, the structure for
is as follows:
Lewis structure for P :
The maximum number of valence electrons in P is = 5.
Thus, the structure for P is=
