Answer:
Option (c) is correct.
Explanation:
According to 2nd law of thermodynamics, every spontaneous process is associated with increase in entropy (
).
As sodium acetate crystallizes out spontaneously therefore it is associated with .
During crystallization, bond formation takes place which results evolution of heat. In other words, crystallization phenomenon is exothermic (
).
So, the given crystallization process renders the following thermodynamic quantities- J/K and J
Option (c) is correct.
Chlorine gas, or dichlorine, is composed of 2 chlorine atoms and has a molar mass of 70.96, or about 71 g. So the answer is the molar mass is 71 g.
Hope this helps!
Answer:
The charge on the nucleus of an atom; controlled by the number of protons and electrons present in an atom.
Explanation:
<span>Group 1 can be characterized as atoms that have 1 electron in their valence shell. This is valuable when dealing with these questions, because the loss or gain of valence electrons is what defines ionic relationships. When group 1 elements form ionic bonds with other atoms, they are extremely likely to lose their valence electron, since the nucleus has a weaker pull on it than, say, a chlorine atom has on its 7 valence electrons. The weaker pull between the nucleus and the valence electron of group 1 elements means that the radius is high, since the electron is more free to move with less pull on it. This also means that the first ionization energy is low, since it takes relatively little energy for that electron to be pulled away to another atom.</span>
