The taste of drinking water can be improved by removing impurities from our municipal water by adding substances to the water th

at precipitate a solid (called a flocculent) that drags down impurities as it settles. One way this is done is to dissolve aluminum sulfate and sodium hydroxide in the water to precipitate aluminum hydroxide. Write the complete equation for this reaction. (Use the lowest possible whole number coefficients. Include states-of-matter in your answer.)

Calculate the number of moles of Cl atoms in 3.01×1024 formula units of magnesium chloride, MgCl2.
natta225 [31]
Answer: 10 moles
To find how many moles, you need to divide the number of atoms with 6.02 * 10^23. Since every magnesium chloride has two chlorine atoms, you need to multiply it by 2. The calculation would be:  3.01×10^24  * 2 / 6.02 * 10^23= 10 moles

Which of the following is NOT something that electromagnetic waves and mechanical waves have in common?
Svetlanka [38]

Answer:

D. In both, vibrations occur in a parallel direction to the direction of the wave.

Explanation:

It is not true that in both mechanical and electromagnetic waves, vibrations occur in  parallel direction to the direction of the wave.

As with all waves, they are disturbances that transfers energy without moving the materials of the medium.

  • Electromagnetic waves have only one way of propagation which is a vibration in both parallel and longitudinal direction.
  • Mechanical waves can be propagated either in a parallel direction or longitudinal direction and not both.
