Explanation / Answer

a) The temperature of the system increases with increase in pressure

b) Volume of system decreases by increasing pressure

c) Pressure of the system decreases by increasing temperature and increasing volume

d) Valance electron in oxygen atom ( electron in outer most shell)

electronic configuration of oxygen = 2,6

so valance electron = 6

e) its make the compound like H2SO4 , or SO42- has capacity to take 2 electron, to complete 8 in outer most shell it must have 6 electron

so valance electron in SO4 2- = 6
