densk [106]3 years ago
5 0

Answer:

It would be compound.

Explanation:

It is this way because if it adds another proton it becomes more positive that nuetral, and if you add an electron it just makes the atom more dense. That is why the answer is compound. Hope this helped :)

What are the limitations of the van der Waals equation.​
jeka57 [31]
Limitations of Van der waal's equation. (i) The value of 'b' is not constant but varies with pressure and temperature. (ii) The value of is not equal to 3b, but actually it is equal to, in some case; and in other cases 2b. (iii) The value of is not equal to but it is usually more than 3 for most of the gases.

Which of the following correctly describes the difference (on average) between an electron in a 2s orbital and an electron in a
bulgar [2K]

Answer:

C: electrons is the 3s orbital are higher than those in the 2s orbital

Explanation:

Looking at the options, the correct one is that the electrons in the 3s orbital will possess more energy than those in the 2s orbital. This is because the the 2s orbitals will be filled with electrons first before the 3s orbital.

Also from basics we know that the energy of an orbital increases as the quantum number increases.

Assuming the boiling point increased by 2 °C, what is the approximate molality of NaCl when the video ends? Kbp(water) = 0.512
makkiz [27]

Answer : The molality of NaCl is, 1.95 mol/kg

Explanation :

Formula used for Elevation in boiling point :

\Delta T_b=i\times k_b\times m

where,

\Delta T_b = change in boiling point = 2^oC

k_b = boiling point constant  for water = 0.512^oC/m

m = molality

i = Van't Hoff factor = 2 (for electrolyte)

The dissociation NaCl will be,

NaCl\rightarrow Na^++Cl^{-}

So, Van't Hoff factor = Number of solute particles = Na^++Cl^{-} = 1 + 1 = 2

Now put all the given values in the above formula, we get:

2^oC=2\times (0.512^oC/m)\times m

m=1.95mol/kg

Therefore, the molality of NaCl is, 1.95 mol/kg
