Rainwater harvesting is the collection and storage of rain, rather than allowing it to run off. Rainwater is collected from a roof-like surface and redirected to a tank, cistern, deep pit, aquifer, or a reservoir with percolation. Dew and fog can also be collected with nets or other tools.

What is the education and training needed for psychologist? In your own words.
MariettaO [177]

To become a psychologist you must of course have obtained a master's or doctoral degree. To receive that students would typically do tons of research, work supervised clinical rotations, and teach classes that all depend on your choice of of specialty(ies) such as counseling, school, or clinical psychology.

Good luck in your future studies, I hope I helped!!

an engineer wishes to design a container that will hold 12.0 mol of ethane at a pressure no greater than 5.00x10*2 kPa and a tem
OleMash [197]

Answer:

The minimum volume of the container is 0.0649 cubic meters, which is the same as 64.9 liters.

Explanation:

Assume that ethane behaves as an ideal gas under these conditions.

By the ideal gas law,

P\cdot V = n\cdot R\cdot T,

\displaystyle V = \frac{n\cdot R\cdot T}{P}.

where

  • P is the pressure of the gas,
  • V is the volume of the gas,
  • n is the number of moles of particles in this gas,
  • R is the ideal gas constant, and
  • T is the absolute temperature of the gas (in degrees Kelvins.)

The numerical value of R will be 8.314 if P, V, and T are in SI units. Convert these values to SI units:

  • P =\rm 5.00\times 10^{2}\;kPa = 5.00\times 10^{2}\times 10^{3}\; Pa = 5.00\times 10^{5}\; Pa;
  • V shall be in cubic meters, \rm m^{3};
  • T = \rm 52.0 \textdegree C = (52.0 + 273.15)\; K = 325.15\; K.

Apply the ideal gas law:

\displaystyle \begin{aligned}V &= \frac{n\cdot R\cdot T}{P}\\ &= \frac{12.0\times 8.314\times 325.15}{5.00\times 10^{5}}\\ &= \rm 0.0649\; m^{3} \\ &= \rm (0.0649\times 10^{3})\; L \\ &=\rm 64.9\; L\end{aligned}.

Chlorine has 17 total electrons with electron configuration 1s^2 2s^2 2p^6 3s^2 3p^5. What are the first two quantum numbers for
nasty-shy [4]

Answer:

Chlorine has 17 total electrons with electron configuration 1s^2 2s^2 2p^6 3s^2 3p^5.

What are the first two quantum numbers for the six electrons in the 2p subshell?

Explanation:

The principal quantum number represents the shell number in which the electron is present.

It is represented with "n".

The next quantum number is the azimuthal quantum number.

It represents the shape of the orbital.

It has values from 0 to (n-1).

Its value depends on the principal quantum number.

Chlorine has 17 total electrons with electron configuration 1s^2 2s^2 2p^6 3s^2 3p^5.

For the six elecetrons in 2p subshell:

The first two quantum number values are the same and their values are:

n=2 , l=1.
