A study of the following system, 4 NH3(g) + 7 O2(g) <--> 2 N2O4(g) + 6 H2O(g), was carried out. A system was prepared with [N2O4] = [H2O] = 3.60 M as the only components initially. At equi­librium, [H2O] is 0.600 M. Calculate the equilibrium concentration of O2(g).

3.50 M

Explanation:

Step 1: Write the balanced equation

4 NH₃(g) + 7 O₂(g) ⇄ 2 N₂O₄(g) + 6 H₂O(g)

Step 2: Make an ICE chart

        4 NH₃(g) + 7 O₂(g) ⇄ 2 N₂O₄(g) + 6 H₂O(g)

I              0               0              3.60            3.60

C         +4x            +7x               -2x             -6x

E            4x              7x           3.60-2x      3.60-6x

Step 3: Calculate the value of x

The concentration of water at equilibrium is 0.600 M. Then,

3.60-6x = 0.600 M

x = 0.500 M

Step 4: Calculate the concentration of O₂ at equilibrium

The concentration of O₂ at equilibrium is 7x = 7(0.500M) = 3.50 M

plants need sunlight, water, and carbon dioxide to make food. plants use the raw materials of water, nutrients they absorb from soil, and carbon dioxide to make sugars the plant can use. energy from the sun and chlorophyll are also needed.
