The standard enthalpy of formation for chlorine is zero but the standard entropy is larger than 0 because it is the elemental state of chlorine.
The standard enthalpy of formation for chlorine is zero because cl2 is the elemental state of chlorine and it does not require any energy for the formation of the standard state of chlorine.
The entropy of any system cannot be negative. It can only be positive or zero.
The entropy of a system will become zero only at a absolute zero temperature.
That's why the entropy of chlorine in elemental state is more than zero because absolutely zero temperature can't be obtained.

Answer: Nitrogen
Explanation: Nitrogen has an atomic number of 7 and an atomic mass of about 14 u
Answer:
Explanation:
<u>Given:</u>
Density = ρ = 0.8 g/cm³
Volume = V = 225 cm³
<u>Required:</u>
Mass = m = ?
<u>Formula:</u>
m = ρV
<u>Solution:</u>
m = (0.8)(225)
m = 180 g
