The sign of ΔSsys for diffusion of perfume vapors through the room is positive.
The measure of disorderliness or randomness of a thermodynamic system is known as entropy. No energy in the universe is completely transferred into work done and that portion of energy increases the randomness of the system.
ΔS is positive when entropy is increases and vice versa. Whenever the randomness of a particular system increase, entropy increases and ΔS becomes positive.
When the perfume vapors diffuse through a room its volume expands which results in increase of the randomness due to the motion of the molecules and hence the sign of ΔSsys becomes positive.

Answer:
maybe
Explanation:
you could be high risk for coronavirus if you have asthma and are not safe.
It’s the third one because Cl has 17 protons bc of the numeric number and 18 electrons bc it’s always the opposite and 18 neutrons because you subtract 35-17=18
