What is solubility? .​
blsea [12.9K]
Solubility is the ability of a solid, liquid, or gaseous chemical substance (referred to as the solute) to dissolve in solvent (usually a liquid) and form a solution. The solubility of a substance fundamentally depends on the solvent used, as well as temperature and pressure.

An element crystallizes in a face-centered cubic lattice. If the length of an edge of the unit cell is 0.408 nm, and the density
V125BC [204]

Answer:

Au

Explanation:

For the density of a face-centered cubic:

Density = \dfrac{4 \times M_w}{N_A \times a^3}

where

M_w = molar mass of the compound

N_A= avogadro's constant

a^3 = the volume of a unit cell

Given that:

Density (\rho) = 19.30 g/cm³

a = 0.408 nm

a = 0.408 \times 10^{-9} \times 10^{2} \ cm

a = 4.08 \times 10^ {-8} \ cm

∴

19.3 = \dfrac{4 \times M_w}{(6.023 \tmes 10^{23})\times (4.08 \times 10^{-8})^3}

M_w= \dfrac{19.3\times (6.023 \times 10^{23})\times (4.08 \times 10^{-8})^3}{4}

M_w=197.37 \ g/mol

Thus, the molar mass of 197.37 g/mol element is Gold (Au).

Someone please help me:
Stels [109]

Answer: The number to the left of AC should be 6.

Explanation: The balanced chemical reaction is one in which the number of atoms  of each element on the reactant side must be equal to the number of atoms on product side.

The given equation A_2B + DC_3 \rightarrow AC + D_2B_3 is unbalanced as the atoms on the reactant side are not same as number of  atoms on product side. This equation is called as skeletal equation.

The balanced chemical equation is :

3A_2B + 2DC_3 \rightarrow 6AC + D_2B_3

Thus the number to the left of AC is 6.
