Answer:
10 electrons
The d sublevel has 5 orbitals, so can contain 10 electrons max. And the 4 sublevel has 7 orbitals, so can contain 14 electrons max.
I have found this variation on the ideal gas equation to be very handy.
PV = nRT ..... n = m / M.... where m is mass, M is molar mass
PV = mRT / M
m = PVM / RT
m = 1.75 atm x 3.00L x 28.0g/mol / 0.0821 Latm/molK / 295K
m = 6.07g
The grams of ammonia are in the flash is a total of 6.07 grams
A . well test explanation for a broad set of observations.
They have two or eight electrons in their valence shell. They do not gain, lose or share electrons.
Answer:
ΔH of solution = ΔH₁ + ΔH₂ + ΔH₃
Explanation:
- Assume that the solution is formed via dissolving solute A in the molecules of Solvent B.
<em>The formation of the solution goes through 3 steps:</em>
1- The dissociation of the solute A particles, solute breaks apart the intermolecular forces holding the molecules together. It has ΔH₁ > 0 beause this is an endothermic process.
2- The dissociation of the solvent B particles, solute breaks apart the intermolecular forces holding the molecules together. It has ΔH₂ > 0 because this is an endothermic process.
3- The particles of the solvent and solute are holding together. It has ΔH₃ < 0 because this is an exothermic process.
- The enthalpy of the solution (ΔH of solution) will be equal to the sum of the enthalpy change of the three steps.
- ΔH of solution = ΔH₁ + ΔH₂ + ΔH₃.
