The continental crust, or the crust that lies beneath the continents, usually ranges from around 30 to 45 kilometers thick. These thicknesses are found on most continents and are dependent on height above sea level and mountainous regions. Although there are rare areas that exceed 70 kilometers thick, according to the United States Geological Survey, or USGS, less than 10 percent of the total area of the Earth's crust exceeds 50 kilometers thick.

Thicknesses below 30 kilometers are typically only found under the ocean and are called oceanic crust. The thinnest sections of the crust are only approximately five kilometers thick, which is a small fraction of the thickness of the thickest parts of the continental crust. The thickness of oceanic crust is difficult to estimate by looking only at proximity to continents or latitude since the crust varies greatly from coast to coast and everywhere in between. For example, along the eastern coast of the United States, the oceanic crust ranges from 10 to 30 kilometers thick, according to the USGS.

Answer is: <span>1.0 mol X left over.
</span>Chemical reaction: X + 2Y → XY₂.
n(X) = 3,0 mol, excess reactant.
n(Y) = 4,0 mol, limiting reagent.
n - amount of substance.
from reaction: n(X) : n(Y) = 1 : 2.
n(X) : 4 mol = 1 : 2.
n(X) = 2 mol, that reacts.
excess of X: 3 mol - 2 mol = 1 mol.

Solutes dissolve in solvents to form a solution. A saturated solution contains just as must solute as it can normally hold.

The solvent in the coffee solution is water and the rest of the chemicals dissolved in the solvent are called solutes. A solution is formed when a solute is dissolved in a solvent.

A saturated solution contains just as much solute as it can normally hold at a particular temperature while a supersaturated solution contains more solute than it can normally hold at a particular temperature.

A polar molecule contains covalent bonds between atoms having an electronegativity difference above 0.5. Such molecules are polar as electrons of the bond are drawn closer to the atom that is more electronegative.

According to Avogadro's law; 6.02 × 10^23 particles is referred to as one mole of particles.

A strong acid has a pH that may range from 0 - 3. A strong base has a pH of around 10 - 14. Water is a neutral substance and has a pH of 7.

From the information provided;

Number of moles of acid = 0.002 moles

Volume of solution= 2 L

Concentration of solution = number of moles/volume = 0.002 moles/2L = 0.001 M

pH = - log[H^+]

pH = - log[0.001 ]

pH = 3

From;

pH + pOH = 14

pOH = 14 - pH
