Condensation is the change from liquid to water cycle
kogti [31]

Answer:

hi! merry xmas!

Explanation:

Condensation is the process where water vapor becomes liquid. It is the reverse of evaporation, where liquid water becomes a vapor.

Condensation happens one of two ways: Either the air is cooled to its dew point or it becomes so saturated with water vapor that it cannot hold any more water.

djyliett [7]
\text{H}_{2(g)}\text{ + CO}_{2(g)}\text{ }\rightleftarrows\text{ H}_2\text{O}_{(g)}\text{ + CO}_{(g)}

The reaction is balanced

The equilibrium constant is defined as the concentration ratio of the products and reactants. They are not considered pure solids and liquids.

\text{ K}_{eq}=\frac{\lbrack\text{CO}\rbrack\lbrack\text{ H}_2\text{O}\rbrack}{\lbrack\text{ H}_2\rbrack\lbrack\text{ CO}_2\rbrack}

So the answer is option B.
