The vapor pressure of the two jars are the same.

The volume of water inside the container does not change the vapor pressure.

As long as the liquid remains being water and the temperature does not change the vapor pressure will be the same. The vapor pressure depends only in the nature of the substance and the temperature of the system.
If you want to know more about this, i.e. why, here you have additional explanation:

The vapor pressure is the pressure of the vapor of a substance in equilibrium with the substance in liquid (or solid state) and it is due to the fact that some molecules in the liquid (or solid), those that are close to the surface of liquid in contact with the gas phase and that have enough kinetic energy, evaporate.

At equilibrium the number of molecules passing from the liquid state to the gas state is equal to the number of molecules that pass from the gas state to the liquid state.  If the volume of liquid is increased or decreased, as long as the temperaature of the system remains constant the equilibrium is reached again with the same vapor pressure.

Of the well-characterized elements of group 7A, which would exhibit the following properties? It reacts with the alkali metals (
dezoksy [38]

Answer:

a. fluorine

Explanation:

Fluorine is the element of group 17 and period 2. The electronic configuration of the element is 1s^22s^22p^5.

Stable oxidation state = -1 of fluorine as it gains one electron to gain noble gas configuration.

With alkali metals, which have oxidation state of +1 form ionic compound of the form, MX where X is F.

Among the halogens, fluorine forms the most stable halide because of the comparable size of the hydrogen and fluorine. Thus, it is the weakest acid when compared with other hydrogen halides.

Fluorine is the most reactive in the halogen series and thus, combines with most of the elements.

Fluorine forms inter-halogen compounds of form XA only. Example - ClF.

Hence, option a is correct.

A reaction produces 0.861 moles of H2O . How many molecules of H2O are produced?
ioda

Answer:

5.19 x 10²³ molecules of H₂O

Explanation:

1 mole => 6.023 x 10²³ molecules of H₂O

0.861 mole => 0.861mole x 6.023 x 10²³ molecules of H₂O

= 5.19 x 10²³ molecules of H₂O

Phantasy [73]

Answer:

1.) At high altitude it takes longer to cook spaghetti.

Explanation:

The first even describes depression in boiling point due to reduction in external pressure . It is not a colligative property.

Depression of freezing  point and elevation of boiling point due to impurity or addition of solute are colligative priperty.
