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:

Percent yield of reaction is 75%.

Explanation:

Given data:

Moles of A = 2.0 mol

Moles of B = 4.0 mol

Moles of C formed = 1.8 mol

Percent yield of reaction = ?

Solution:

Chemical equation:

2A + 5B → 3C + D

We will compare the moles of A and B with C from balance chemical equation.

A : C

2 : 3

B : C

5 : 3

4 : 3/5×4 = 2.4 mol

Number of moles of C formed by 4 moles B are less thus B is limiting reactant and will limit the yield of C.

Percent yield:

Percent yield = actual yield /theoretical yield × 100

Percent yield = 1.8 mol / 2.4 × 100

Percent yield =75%

3) List two other names for P-waves and for S-waves.

Dimas [21]

3. Other names for S- waves are secondary waves, shear waves, and sometimes elastic S-waves. Other names for P-waves are primary waves and compressional waves.
4. You need 3 stations, because scientists find the difference between the arrival times of the primary and the secondary waves at each of the 3 stations, then the time difference is used to determine the distance of the epicentre from each station. The greater the difference in time, the further away the epicentre is. A circle is drawn around each station, with a radius corresponding to the epicentre’s distance from that station. The point where the three circles meet is the epicentre. If you only had two stations, you could only predict the epicentre, as the point where all three circles meet wouldn’t be complete, you’d have to try and estimate where the third one would intercept. This would greaten the chance of error and isn’t as accurate.

Hope this helps!

<span>In the periodic table, the elements are organized into groups based on putting together elements with similar properties. For instance, elements in each group have the same number of valence electrons, which makes them form similar bonds. Additionally, elements in the same similar characteristics, such as malleability and magnetism.</span>
