The term for free electrons in metals transferring energy by colliding with other atoms or electrons is _____.
shepuryov [24]
Conduction

In metals, the electrons of each atom are delocalized, which means they are free to move about in the structure of the metal. When heat is applied at one end of the metal, the electrons there are excited and collide with surrounding particles, transferring their energy to them. This is what makes metals very good conductors of both heat and electricity.

six different aqueous solutions are represented in the beakers below, and there total volumes are noted. (a) which solution has
wolverine [178]

The molarity of the solutions are as follows:

  • solution B has the highest molarity
  • solutions A, D and F have the same molarity
  • solutions A and C are mixed together have a lower molarity than B
  • solution F and D will have the same molarity
  • Volume of water required to be evaporated is 8.3 mL

<h3>What is molarity of a solution?</h3>

The molarity of a solution is the amount in moles of a substance present in a given volume of solution.

From the image of the solution given:

  • solution B has the highest molarity
  • solutions A, D and F have the same molarity
  • when solutions A and C are mixed, the resulting solution have a lower molarity than B
  • solution F and D will have the same molarity after 75 mL and 50 mL of water are added to each respectively
  • the molarity of B is 12/50 = 4/16.7. Volume of water required to be evaporated = 25 - 16.7 = 8.3 mL

Therefore, the molarity of the solutions depends on the moles of substance present per given volume of solution.

As a pilot is flying in level flight at 9,500 ft, the altimeter in the instrument panel is set to a pressure of 29.48 mm of Hg.
bearhunter [10]

Answer:

from the ideal gas law, P2 /P1 = T2 /T1 for the same volume and quantity of gas. P2 = (758 mmHg) (45 +273 K) / (15 +273K) = 837 mmHg.
