Answer:

Diffusion is the movement of solutes from an area of higher concentration to an area of low concentration.

Explanation:

In chemistry, diffusion is the movement of molecules or atoms from an area of higher concentration to an area of low concentration. How it works is that molecules in motion from thermal energy randomly move about. Over time, this leads to the distribution of different particles in your volume solution.

Or each set of elements represented in this periodic table outline, identify the principal quantum number, n , and the azimuthal

Tems11 [23]

The answer is potassium. It would be 4, and for neon would be 2. Just total which row of the periodic table you are on. The "L" tells you whether the highest-energy electron is in an "s" orbital (L=0) or a "p" orbital (L=1) or a "d" orbital (L=2) or an "f" orbital (L=3). The way in which these orbitals are filled is: for each of the first three rows (up to argon), two electrons in the "s" orbital are filled first, then 6 electrons in the "p"orbitals. The row where the potassium also starts with filling the "s" orbital at the new "n" level (4) but then goes back to satisfying up the "d" orbitals of n=3 before it seals up the "p"s for n=4.

What electrically neutral atom will have an electron configuration of 1s2 2s2 2p4?

abruzzese [7]

Answer:- oxygen.

Explanations:- The electronic configuration is given and we are asked to figure out the electrically neutral atom that will have the electron configuration, $1s^22s^22p^4$ .

The sum of electrons for this electron configuration is 8. If we look at the periodic table then 8 is the atomic number of oxygen.

So, the electrically neutral atom for the given electron configuration is oxygen.

How many 20.0-g ice cubes are required to absorb 47.0 kJ from a glass of water upon melting?

Sati [7]

Hello!

The number of 20-g ice cubes required to absorb 47 kJ from a glass of water upon melting is 7 icecubes

Why?

We are going to clear from the equation of the released heat, the mass of ice (m). The specific latent heat of fusion of ice is 336 kJ/kg:

$Q=m*L\\ \\ m=\frac{Q}{L}=\frac{47 kJ}{336 kJ/kg}=0,1399 kg=139,88 g\\ \\ 139,88g*\frac{1 icecube}{20g}=6,99=7icecubes$

So, 7 ice cubes are required to absorb that amount of heat from the glass of water.

Have a nice day!
