<u>Answer:</u> The correct answer is
<u>Explanation:</u>
Aluminium is the 13th element of the periodic table with electronic configuration of
This element looses 3 electrons and shows an oxidation state of +3.
Oxygen is the 8th element of the periodic table with electronic configuration
This element will gain 2 electrons and shows an oxidation state of -2.
By criss-cross method, the oxidation state of aluminium and oxygen gets revered and they form the coefficients of the compound.
Hence, the compound formed will have the chemical formula of

Answer:
Explanation:
The relation between Kp and Kc is given below:
Where,
Kp is the pressure equilibrium constant
Kc is the molar equilibrium constant
R is gas constant
T is the temperature in Kelvins
Δn = (No. of moles of gaseous products)-(No. of moles of gaseous reactants)
For the first equilibrium reaction:
Given: Kc = 0.50
Temperature =
R = 0.082057 L atm.mol⁻¹K⁻¹
Δn = (2)-(3+1) = -2
Thus, Kp is:
