Answer: Option (D) is the correct answer.

Explanation:

Vapor pressure is defined as the pressure exerted by the vapors which are present on the surface of a liquid.

For example, vapor pressure of water at room temperature is 0.0313 atm.

On the other hand, the temperature at which the vapor pressure of a liquid equals atmospheric pressure is known as boiling point.

For example, boiling point of water at room temperature is 100^{o}C.

Thus, we can conclude that vapor pressure can be described as the pressure exerted by a gas above the surface of its liquid.

Which represents the correct electron distribution of a transition element in the ground state?
Phoenix [80]
I believe both C) and D) are correct, because both have enough electrons to show that the element has enough protons to be a transition metal, and both elements seem to have an electron configuration that exists in the ground state. We may need more information.

Determine the oxidation states of the elements in the compounds listed. None of the oxygen-containing compounds are peroxides or
natka813 [3]

Answer:

Explanation:

You need to remember that the oxidation number of H is +1, except when it is in a metal hydrites like NaH, where its oxidation number is -1. Then, the oxidation number of O is -2, but in peroxides is -1. So with these rules you just have to multiply the ox. number with the name of atoms and all the elements in the reaction must sum 0.

Which of the following correctly illustrates the mass of reactants and products for the reaction below?
Marina CMI [18]

Answer:

The mass of reactants and products for the reaction is this:

- 92 g Na, 32 g O₂, 124 g Na₂O

which is not a choice from the list.

Explanation:

4 moles of Na reacts with 1 mol of oxygen to produce 2 moles of sodium oxide.

Na = 23 g/m

4 moles are (4 . 23) = 92 g

O₂ = 32 g/m

It's a diatomic molecule (each O is 16 g/m)

Na₂O = 62 g/m

2 mol of sodium oxide will be (2 .62) = 124 grams

The mass of reactants and products for the reaction is this:

- 92 g Na, 32 g O₂, 124 g Na₂O

which is not a choice from the list.
