Answer:
It would take 3.64 hours to travel.
Explanation:
200km with 55 per hour.
200 divided by 55 would equal 3.64.
I am dividing because to solve time would be distance/rate.
I hope this helps! :)
Answer:
The amount of moles of Fe in 5.22*10²² atoms of Fe is 0.0867.
Explanation:
Avogadro's Number or Avogadro's Constant is called the number of particles that make up a substance (usually atoms or molecules) and that can be found in the amount of one mole of said substance. Its value is 6.023*10²³ particles per mole. Avogadro's number represents a quantity without an associated physical dimension, so it is considered a pure number that allows describing a physical characteristic without an explicit dimension or unit of expression. Avogadro's number applies to any substance.
Then you can apply the following rule of three: if 6.023*10²³ atoms are contained in 1 mole, 5.22*10²² atoms are contained in how many moles?
amount of moles= 0.0867
<u><em>The amount of moles of Fe in 5.22*10²² atoms of Fe is 0.0867.</em></u>
Answer:
True
Explanation:
The center receives pressure which is what creates convection currents
Answer:
Option (2)
Explanation:
Since the amount of each sample is the same, we are looking for the metal with the greatest density, which is copper.
