An atom is most stable when it has eight electrons in its outermost energy level.
Answer:
Sodium (Na) and Chlorine (CI)
Explanation:
so one liter is about 2. something gallons so at 12.8 km/l you would get about 30 mpg which is insane but yeah
<u>Answer:</u> The entropy change of the process is 
<u>Explanation:</u>
To calculate the entropy change for different phase at same temperature, we use the equation:

where,
= Entropy change
n = moles of acetone = 6.3 moles
= enthalpy of fusion = 5.7 kJ/mol = 5700 J/mol (Conversion factor: 1 kJ = 1000 J)
T = temperature of the system = ![-94.7^oC=[273-94.7]=178.3K](https://tex.z-dn.net/?f=-94.7%5EoC%3D%5B273-94.7%5D%3D178.3K)
Putting values in above equation, we get:

Hence, the entropy change of the process is 
If the question includes x only than it’s value would be 1
