Here's one! those spots are actually storms:)
Answer:
Calcium (Ca) and Scandinavium (Sc)
Explanation:
They are all on the same period.
Answer:
Explanation:
Hello,
The six-carbon benzene ring contains two types of bonds: C-C and C-H bonds, that are -hybridized σ bonds, and the six π bonds that form the aromatic ring. The σ bonds form from one 
orbital and two 
orbitals from each carbon, which then bond the carbon to the two carbons on either side and the carbon's single hydrogen. The remaining orbital from each carbon atom sticks out above and below the plane of the ring; these orbitals overlap sideways, rather than lengthwise, to form the aromatic π bond system.
Best regards.
a. W = 0 J
b. W = - 308.028 J

Given
Nitrogen gas expands in volume from 1.6 L to 5.4 L

The work done
Solution
Isothermal :
W = -P . ΔV
Input the value :
a. At a vacuum, P = 0
So W = 0
b. At pressure = 0.8 atm
W = - 0.8 x ( 5.4 - 1.6)
W = -3.04 L.atm ( 1 L.atm = 101.325 J)
W = - 3.04 x 101.325
W = - 308.028 J
