Compare S (secondary) waves and P (primary) waves. Why do they travel at different speeds?

Chemistry
1 answer:
Amanda [17]3 years ago
8 0

S waves

  • These are shear waves .
  • The motion of the medium is perpendicular to  direction of propagation of the wave .
  • They can propagate only through solids and not through gases or liquids .
  • S waves are larger .
  • They travel with less speed .

P waves

  • These are compression waves .
  • These waves produces a force along the direction of propagation .
  • They can propagate through solids, gases and liquids.
  • P waves are smaller than s waves .
  • They travel with 60% greater speed than S waves .

P-waves travel 60% faster than S-waves on average because the interior part of the Earth does not react the same way as the s wave and P wave.

Define shielding and effective nuclear charge. What is the connection between the two?
ivolga24 [154]

Answer:

The relation between the shielding and effective nuclear charge is given as

Z_{eff} = Z -S

where s denote shielding

z_{eff} denote effective nuclear charge

Z - atomic number

Explanation:

shielding is referred to as the repulsion of an outermost electron to the pull of electron from valence shell.  Higher the electron in valence shell higher will be the shielding effects.  

Effective nuclear charge is the amount of net positive charge that valence electron has.

The relation between the shielding and the effective nuclear charge is given as  

Z_{eff} = Z -S

wheres denote shielding

z_{eff} denote effective nuclear charge  

Z - atomic number

Can 1750 mL of water dissolve 4.6 moles of Copper Sulfate CuSO4? _________ Why? / Why not?
Wewaii [24]

Answer:

  • <u>No, you cannot dissolve 4.6 moles of copper sulfate, CuSO₄, in 1750mL of water.</u>

Explanation:

This question is part of a Post-Lab exercise sheet.

Such sheet include the saturation concentrations for several salts.

The saturation concentration of Copper Sulfate, CuSO₄, indicated in the table is 1.380M.

That means that 1.380 moles of copper sulfate is the maximum amount that can be dissolved in one liter of solution.

Find the molar concentration for 4.6 moles of copper sulfate in 1,750 mL of water.

You need to assume that the volume of water (1750mL) is the volume of the solution. This is, that the 4.6 moles of copper sulfate have a negligible volume.

<u>1. Volume in liters:</u>

  • V = 1,750 mL × 1 liter / 1,000 mL = 1.75 liter

<u />

<u>2. Molar concentration, molarity, M:</u>

  • M = number of moles of solute / volume of solution in liters

  • M = 4.6 moles / 1.75 liter = 2.6 M

Since the solution is saturated at 1.380M, you cannot reach the 2.6M concentration, meaning that you cannot dissolve 4.6 moles of copper sulfate, CuSO₄ in 1750mL of water.
