i need help for the three questions

Write the equilibrium constant expression, Kc, for the following reaction: Please enter the compounds in the order given in the reaction. If either the numerator or denominator is 1 , please enter 1 NH3(g)+HI(g)[[NH4I(s) Write the expression for the equilibrium constant Kp for the following reaction. Enclose pressures in parentheses and do NOT write the chemical formula as a subscript. For example, enter (PNH3)2 as (PNH3)2. If either the numerator or denominator is 1 , please enter 1 2Ag2O3(s)2Ag2O2(s)+O2(g) Write the expression for the equilibrium constant Kp for the following reaction. Enclose pressures in parentheses and do NOT write the chemical formula as a subscript. For example, enter (PNH3)2 as (PNH3)2. If either the numerator or denominator is 1 , please enter 1 NH4F(s)NH3(g)+HF(g)
