If an aqueous solution has a ph of 5.57 what is the concentration of hydroxide ion ([oh-]) in the solution?
irga5000 [103]
PH=5.57
pH+pOH=14
5.57 + pOH=14
pOH = 14-5.57= 8.43

pOH = - log  [OH⁻]
-pOH=  log  [OH⁻]


[OH^{-}] = 10^{-pOH}= 10^{-8.43}= 3.72*10^{-9}

 [OH^{-}]= 3.72*10^{-9}

What happens when the vapor pressure of a liquid is equal to the external pressure? The liquid freezes The intermolecular forces
Makovka662 [10]

Answer:

The liquid boils.

Explanation:

Vapor pressure is simply defined as the pressure exerted on a substance (solid/liquid) by the vapor of the substance collected just at the top of the surface of the substance. In concise words, it is the pressure of Vapor that is in contact with its solid or liquid state.

For a liquid, it is the pressure of the Vapor gathering at the top of the surface of the liquid.

When this Vapor pressure matches the external pressure, the temperature stays constant and the molecules of the liquid all through the liquid can gain enough energy, rise to the surface of the liquid and break free in gaseous form; thereby, boiling.

The definition of boiling point basically explains that it is the point at which temperature stays constant, and the vapour pressure of the liquid matches the atmospheric/external pressure around the liquid and its liquid molecules change into vapor.

This is why liquids boil faster at higher altitudes; the atmospheric pressure at higher altitudes is reduced, hence, the temperature at which liquid boils at this high altitude is normally lower than its known boiling point temperature.

It is also why food cooks to a temperature higher than the boiling point of water in a pressure cooker/pot. The added pressure ensures that the cooking water boils at temperatures higher than its boiling point; thereby exposing the cooking ingredients to a higher temperature, leading to faster cooking.

Hence, it is obvious why boiling is the answer to this question.

The products and the reactants are the components of the reaction. The equation of phosphoric acid represents the decomposition reaction as it forms oxygen and water. Thus, option a is correct.

<h3>What is a decomposition reaction?</h3>

A decomposition reaction is a  chemical breakdown of the reactant into two or more products. The large and complex compound breaks into smaller and simpler molecules.

The following equation, 4 H₃PO₄ → P₄ + 5 O₂ + 6 H₂O is an example of decomposition as phosphoric acid breaks into phosphorus, water, and oxygen molecules.

Therefore, option a. the reaction of phosphoric acid is a decomposition reaction.

How many moles of oxygen atoms are present in 0.4 moles of oxygen gas​
Agata [3.3K]

Answer:

Each molecule of O2 is made up of 2 oxygen atoms. So 1 mole of O2 molecules is made up of 2 moles of oxygen atoms. Therefore 1 mole of oxygen gas contains 2 moles of oxygen atoms. And 0.4 moles of oxygen gas contains 0.8 moles of oxygen atoms.
