17.6
Explanation:
Answer is explained above
Magnesium chloride is the name for the chemical compounds with the formulas MgCl2 and its various hydrates MgCl2(H2O<span>)x. These salts are typical ionic halides, being highly soluble in water. The hydrated magnesium chloride can be extracted from brine or sea water.</span>
A. They are the most destructive earthquake waves.
D. They can move in a rolling pattern through rock, like an ocean wave.
Explanation:
Surface waves are seismic waves that cause the most destruction during an earthquake.
Rayleigh waves are known to cause rolling pattern of rocks just like an ocean waves.
- Seismic waves are elastic waves that notably transmits energy.
- They usually accompany earthquakes.
- There are two broad categories of these waves.
- Surface and body waves.
- Seismic surface waves are low frequency and long wavelength waves.
- They travel very close to the surface.
- They are made up of Love and Rayleigh waves.
- Love waves travels laterally in a horizontal fashion.
- Rayleigh waves rolls like ocean waves in the ground.
- The bulk of the destruction caused during an earthquakes is due to these waves.
- They are the last waves to arrive a seismic station

The number of moles of sodium dichromate from the number of moles of oxygen atoms can be determined through stoichiometry. Using the molecular formula of the compound, Na2Cr2O7, 1 mole of the compound contains 7 moles of oxygen. Hence, 14 moles O2*(1 mole Na2Cr2O7/ 7 mole O2) is equal to 2 moles <span>Na2Cr2O7.</span>
