What is the vapor pressure of water at 105c

The water pressure at  105 ∘ C  is 908.7641 mmHg.

Explanation:

The Antoine equation describes the relationship between the temperature and the vapor pressure of pure substances. In other words, it is an equation used to obtain the value of the vapor pressure as a function of temperature for pure components, and is based on a correlation of three parameters A, B and C. The Antoine equation is:

where:

In the image you can see the values of the Antoine parameters for two temperature ranges for water. In these data the unit of temperature is ° C and the pressure to be calculated will be in mmHg.

In this case, since the temperature is 105 ° C, the temperature range of interest from 99 to 374 ° C. Then the parameters will have the following values: A = 8.14019, B = 1810.94 and C = .244.485

Replacing in the previous equation you get:

Solving, you get as a result:

P=908.7641 mmHg

The water pressure at  105 ∘ C  is 908.7641 mmHg.

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!
