Given the following reaction at equilibrium at 450.0 °C:

CaCO 3 (s) ⇌ CaO(s)+CO 2 (g)

If pCO 2 =0.0160 atm, K c = ?

A) 0.0160
B) 0.0821
C) 2.45 x 10-3
D) 2.70 x 10-4
E) 2.72 x 10-4

Ineed this awnser fast select the correct answer. this chemical equation represents the burning of methane, but the equation is incomplete. what is the missing coefficient in both the reactants and the products? ch4 + → co2 + a. 0 b. 1c. 2d. 3 e. 4
