The correct answer is B.
The crystalline structure of solid is the most to determine the entropy of a solid. Entropy can be termed as disorder or chaos in a closed system.
The densest solid is Osmium. To determine the solubility products in solids in water is tabulated in specified pressure and temperature.

Answer:

The crystalline structure of the solid

Explanation:

The third law of thermodynamics has to do with entropy. It states that the entropy of a perfectly ordered crystal lattice is zero at the absolute zero temperature.

Let us be reminded that entropy is the degree is disorderliness in a system. Hence, atoms of a crystal lattice stop moving as the system approaches absolute zero, the entropy also tends to a constant value.

This clearly shows that the crystalline structure of a solid material determines the degree of entropy of the solid.

Answer:

615 g

Explanation:

In order to convert from moles of any given substance into grams, we have to use said substance's <em>molar mass</em>, as follows:

  • # moles * Molar mass = grams of substance.

Thus, we now <u>calculate the molar mass of beryllium iodide</u>, BeI₂, using the <em>molar masses of the elements</em>:

  • Molar Mass of BeI₂ = Molar Mass of Be + (Molar Mass of I)*2 = 262.821 g/mol

Finally we <u>calculate how many grams are there in 2.34 moles of BeI₂</u>:

  • 2.34 mol * 262.821 g/mol = 615 g

Which part of the periodic table contains elements with the greatest metallic properties?
KiRa [710]
The bottom of group 1. Francium (or Fr) is the element with the greatest metallic properties.

Francium is not a naturally-occurring element, however. It is man-made. There is an isotope of francium that exists naturally, but it's half life is so short that it decays almost instantly into a different element.

The naturally-occurring element with the highest metallic properties is cesium (or Cs), located right above francium.

Metallic characteristics decrease as you move from left to right on the periodic table.

A student dissolves 0.0688 mol of sodium hydroxide in water to make a 0.250 L solution. What is the molarity of the solution?
den301095 [7]
Number of moles = 0.0688 moles of NaoH

volume = 0.250 L

Molarity = moles of solute / volume ( L )

M = 0.0688 / 0.250

M = 0.28 M

Which group of factors are most important in determining the composition of ocean water? a.)temperature, salinity, and density b
Elis [28]

Temperature, salinity, and density are the group of factors are most important in determining the composition of ocean water.

a.)temperature, salinity, and density

<u>Explanation:</u>

The three fundamental factors that help in determining the composition of ocean water are temperature, salinity, and density. Temperature, saltiness, salinity, and density influence the thickness of seawater.

Enormous water masses of various densities are significant in the layering of the sea water (increasingly thick water sinks). As temperature builds water turns out to be less thick. As saltiness builds water gets denser. The temperature helps in deciding the pace of vanishing of the ocean.
