The answer is 10. Each capital letter is an atom. The tiny numbers represent how many atoms of that type
Answer : The value of change in entropy for vaporization of water is 
Explanation :
Formula used :

where,
= change in entropy of vaporization = ?
= change in enthalpy of vaporization = 40.7 kJ/mol
= boiling point temperature of water = 
Now put all the given values in the above formula, we get:



Therefore, the value of change in entropy for vaporization of water is 
Although it has a negative charge, it will never accept a

Answer:
B
Explanation:
They lose energy and slow down and move closer to other gas molecules and the molecules collect together to form a liquid
