Vinegar is an ingredient commonly used by chefs. Scientists also use it as well, although they call it acetic acid. When vinegar is in its liquid or solid (frozen) states, it has a fixed volume. But when vinegar is in its gas state, it takes up the entire volume of whatever container it is in. This is why you can smell an open bottle of vinegar the minute you walk into a kitchen, even though you cannot actually see the gas particles!

Which statement best explains why the volume of vinegar gas is changeable as opposed to the fixed volume of its solid and liquid states?

A. Gas particles are always at a higher pressure than solids and liquids.

B. Gas particles are always at a higher temperature than solids and liquids.

C. Gas particles are spaced far apart and can move freely.

D. Gas particles stay close together but can move around each other.

Answers

Answer 1

Answer: C

Explanation: Because gas particles are free to move fast where as liquid can move a little but solid cant so it would be C

A sample of H2 gas (12.28 g) occupies 100.0 L at 400.0 K and 2.00 atm. A sample weighing 9.49 g occupies ________ L at 353 K and 2.00 atm.

Answers

Considering the ideal gas law, a sample weighing 9.49 g occupies 68.67 L at 353 K and 2.00 atm.

Ideal gases are a simplification of real gases that is done to study them more easily. It is considered to be formed by point particles, do not interact with each other and move randomly. It is also considered that the molecules of an ideal gas, in themselves, do not occupy any volume.

An ideal gas is characterized by three state variables: absolute pressure (P), volume (V), and absolute temperature (T). The relationship between them constitutes the ideal gas law, an equation that relates the three variables if the amount of substance, number of moles n, remains constant and where R is the molar constant of the gases:

P× V = n× R× T

In this case, you know:

P= 2 atmV= ?n= [tex]9.49 gramsx\frac{1 mole}{2 grams} = 4.745moles[/tex] being 2g/mole  the molar mass of H2, that is, the amount of mass that a substance contains in one mole.R= 0.082 [tex]\frac{atmL}{molK}[/tex]T= 353 K

Replacing:

2 atm× V = 4.745 moles× 0.082[tex]\frac{atmL}{molK}[/tex]× 353 K

Solving:

V = (4.745 moles× 0.082[tex]\frac{atmL}{molK}[/tex]× 353 K)÷ 2 atm

V= 68.67 L

Finally, a sample weighing 9.49 g occupies 68.67 L at 353 K and 2.00 atm.

Answers

The empirical formula of the compound (calcium bromide) is CaBr₂

From the question given above, the following data were obtained:

Ca = 4.02 g

Br = 15.95 g

Empirical formula =?

Divide by their molar mass to obtain their mole

Ca = 4.02 / 40 = 0.1005 mole

Br = 15.95 / 80 = 0.199 mole

Divide by the smallest to obtain the mole ratio

Ca = 0.1005 / 0.1005 = 1

Br = 0.199 / 0.1005 = 2

Therefore, the empirical formula of calcium bromide is CaBr₂

given that the radiusof anion a2- is 0.290 nm, what would you expect the radius of a and a2+ to be

Answers

This problem is providing the ionic radius of an anion, A²⁻ as 0.290 nm and asks for that of the cation A²⁺ in comparison to the former.

Firstly, we need to recall the concept of ionic radius, as the distance between the nucleus and the outermost electron shell of an ion. In such a way, we can have two scenarios:

1. Anions result from the gain of electrons exhibited by a nonmetal, which means they turn out bigger than the neutral atom.

2. Cations result from the loss of electrons exhibited by a metal, which means they turn out smaller than the neutral atom.

With the aforementioned, we infer that the cation A²⁺, will me smaller than the anion A²⁻, which means it will have an ionic radius smaller than 0.290 nm.

Answer:

D. Na has a larger radius than Na+ because Na+ has lost its outermost energy shell.

Explanation:

The radius is larger because the diameter of Na+ is larger.

Sodium has smaller atomic  radius than sodium cation because sodium has expanded electron cloud.

What is atomic radius?

Atomic radius is defined as the  distance between outermost shell and the nucleus. Atomic radius varies across the periodic table where in groups it increases due to the fact that new shells are added on moving sown the group.

While in a period it decreases from left to right across the periodic table as electrons are added to the same shell which causes contraction of the atom.In case of comparison between an atom and a cation an atom has smaller atomic radius due to presence of electrons while in case of ions atomic radius is smaller as they have less number of electrons.

Atoms have expanded electron cloud while the electron cloud in case ions is small , the reason being the presence of large number of electrons in case of atoms and less number of electrons in case of ions.

Answers

Answer:

Explanation:

new oceanic crust will form.

The formation of a new oceanic crust will be the primary result of the continuation of the geologic processes. Therefore, option (B) is correct.

What is the oceanic crust?

The oceanic crust can be described as the uppermost layer of the oceanic portion of the tectonic plates. The oceanic crust is composed of the upper oceanic crust, with pillow lavas complex, and the lower oceanic crust, made of troctolite, and ultramafic cumulates.

The oceanic crust lies above the rigid uppermost layer of the mantle. The crust and the rigid upper mantle layer together compose the oceanic lithosphere.

The oceanic crust is rich in iron and magnesium and composed of mafic rocks. It is thinner than the continental crust less than 10 Km thick but it is denser with 3.0 g/cm³ as opposed to the continental crust.

The oceanic crust displays a symmetrical pattern of positive and negative magnetic lines emanating from the mid-ocean ridge.

The heat of vaporization of aluminium at 25 °C is 315.8 kilojoules per mole.

The sublimation is the phase change of a substance from solid to gas, the fusion is the phase change of a substance from solid to liquid and the vaporization is the phase change of a substance from liquid to gas. The heat of vaporization is the difference between the heat of sublimation and the heat of fusion, that is to say:
