Write an expression for the equilibrium constant for this reaction.
NH4CONH2(s) 2NH3(g) + CO2(g)

K= [NH3]^2 [CO2]

Explanation:

Equilibrium constant is products/reactants. Also, in the equation, only gases and aqueous components are included thus solid is not included in the equation above.

in cartography, a contour line (often just called a "contour") joins points of equal elevation (height) above a given level, such as mean sea level. a contour map is a map illustrated with contour lines, for example a topographic map, which thus shows valleys and hills, and the steepness or gentleness of slopes.

explanation:

the answer is option a.
