Consider the following equilibrium: h2o(g) + co(g) h2(g) + co2(g) a closed container is initially filled with h2o and co. which of the following correctly describes the reaction as it proceeds towards equilibrium?
a. the [co] and [co2] both increase.

b. the [co] decreases and [co2] increases.

c. the [co] increases and [co2] decreases.

d. the [co] and [co2] both decrease.

The answer is b. The H2O and CO have to decrease in order to produce the CO2 and H2

You would be correct, boiling water does disinfect contamination.    the property of disinfecting means to kill  germs, bacteria and other pathogens or contamination  that might cause an infection or cause a person to become sickly. a couple methods of disinfecting are using soap, other cleaning supplies or by simply "boiling" the contaminate.  the reason why boiling water disinfects certain attributes is because some cells cannot survive the heat and pressure.
