The human eye contains a certain protein called rhodopsin that changes shape when it is exposed to light. When rhodopsin absorbs

light, part of it undergoes a chemical change. This is how eyes sense the presence of light.

The human eye contains a molecule called 11-cis-retinal that changes conformation when struck with light of sufficient energy. The change in conformation triggers a series of events that results in an electrical signal being sent to the brain. The minimum energy required to change the conformation of 11-cis-retinal within the eye is about 164 {\rm kJ}/{\rm mol}.

a sample of h2 gas is collected over water at 23 degrese celsius, if the observed pressure is 750.0 torr, calculate the partial
Ivahew [28]

Answer:

728.9 torr

Explanation:

Collecting a gas over water results in gathering a mixture of gases. First of all, the target gas is collected, but the gathered sample also contains saturated water vapor.

The saturated water vapor always produces the same pressure which depends on temperature. At a given temperature of 23 degrees Celsius, the saturated vapor pressure is equal to 21.1 torr.

The total pressure is equal to the sum of partial pressures of water and hydrogen:

p = p_{H_2O} + p_{H_2}

Solving for the partial pressure of hydrogen:

p_{H_2} = p - p_{H_2O} = 750.0~torr - 21.1~torr = 728.9~torr
