Answer:
Two equivalent resonance forms can be drawn
Explanation:
In Lewis structure, total valence electrons of constituting atoms are used to draw structure by obeying octet of all atoms and duet of hydrogen atoms.
Least electronegative atom (except hydrogen atom) are considered as central atom.
In , S is the least electronegative atom. Hence it is the central atom.
Number of valence electron of S is 6 and valence electron of O is 6.
So, total number of valence electrons in is 18.
By using this 18 electrons and obeying octet for S and O, two equivalent resonance forms can be drawn.
Structure of resonance forms has been given below.

Answer:
1.84 L
Explanation:
Using the equation for reversible work:
Where:
W is the work done (J) = -287 J.
Since the gas did work, therefore W is negative.
P is the pressure in atm = 1.90 atm.
However, work done is in joules and pressure is in atm. We can use the values of universal gas constant as a convenient conversion unit. R = 8.314 J/(mol*K); R = 0.0821 (L*atm)/(mol*K)
Therefore, the conversion unit is 0.0821/8.314 = 0.00987 (L*atm)/J
is the initial volume = 0.350 L
is the final volume = ?
Thus:
(-287 J)*0.00987 (L*atm)/J = -1.9 atm*( - 0.350) L
= [(287*0.00987)+(1.9*0.350)]/1.9 = (2.833+0.665)/1.9 =1.84 L
