Explanation:</h3>
<u>Step 1: Identify</u>
MgCl₂
<u>Step 2: Find Formula Weight</u>
[PT] Molar Mass of Mg - 24.31 g/mol
[PT] Molar Mass of Cl - 35.45 g/mol
Molar Mass of MgCl₂ - 24.31 + 2(35.45) = 95.21 g/mol
Answer:
The entropy of the products of a reaction is always greater than the entropy of the starting materials
Explanation:
The second Law of Thermodynamics says that entropy always increases
A + B ----> AB
A and B that were completely arranged in their structures had to be completely messy to form compound AB
When an isolated system reaches a maximum entropy configuration, it can no longer undergo changes: it has reached equilibrium.
The best answer would be because there might be an accident.
I believe this nuclide is potassium with the symbol K. Atomic number for an element remains constant no matter how the mass changes. From the periodic table, potassium has an atomic number of 19.
B is the correct answer! I learned this in class last week :)
