katovenus [111]

Water combines with carbon dioxide to produce slightly acidic groundwater

that dissolves limestone and forms caves.

This is because the reaction between water and carbondioxide to form

bicarbonate ions( HCO₃⁻). The bicarbonate ions dissociate into Hydrogen

atoms thereby increasing the acidity.

The acidic environment results in the formation of acidic groundwater that

dissolves limestone and forms caves.

Given the following UNBALANCED reaction: NH3 (g) <--> N2 (g) + H2 (g) If 1

Yakvenalex [24]

Answer:

C. 1.35

Explanation:

2NH3 (g) <--> N2 (g) + 3H2 (g)

Initial concentration 2.2 mol/0.95L 1.1 mol/0.95L 0

change in concentration 2x x 3x

-0.84 M +0.42M +1.26M

Equilibrium 1.4 mol/0.95L=1.47M 1.58 M 1.26 M

concentration

Change in concentration(NH3) = (2.2-1.4)mol/0.95 L = 0.84M

Equilibrium concentration (N2) = 1.1/0.95 +0.42=1.58 M

Equilibrium concentration(NH3) = 1.4/0.95 = 1.47M

K = [N2]*{H2]/[NH3] = 1.58M*1.26M/1.47M = 1.35 M
