The answer is chlorine
That is chlorine is the green-yellowish gas that is used as a disinfecting agent.
Among the options, iodine is a solid ,bromine is liquid while fluorine and chlorine are gases.
Chlorine is greenish yellow colored gas while fluorine is pale yellow, chlorine is used as a disinfecting agent and oxidizing agent as well.
Answer:
work = 3.45 Joules
Explanation:
Work from the 1st Law of Thermodynamics is PΔV in the equation of internal energy => ΔE = ΔH + PΔV.
Therefore, work = PΔV = 2.07atm·(2.334L - 0.666L) = 3.45 L·atm = 3.45 Joules
the answer is physics all i did was put this question in google and got the answer
so hope this helps you mark brainiest if this helped you
1.75 moles of Solute or 1.75n.
To find this, you'll need to use the molarity equation which is M = 
List the given items to organize better:
M (Molarity) = .35
V (Volume) = 5L [must always be in Liters]
n (Moles) = ?
Now, for the equation, substitute the variables with the given numbers:
.35 = 
Isolate the variable by multiplying the volume, 5, onto both sides. This will give you the answer of:
1.75 = n
Hope this helps!
They don't react with other elements under normal conditions as they are already in a low energy or stable state
