Problem page what kind of intermolecular forces act between a dichlorine monoxide molecule and a hydrogen bromide molecule?

Chemistry

Answer:

Intermolecular forces present between Cl_{2}O and HBr are- London force and ion-dipole force.

Explanation:

All molecules contain electrons. Therefore London dispersion force is present between all molecules.

Cl_{2}O is an angular molecule. Also oxygen atom is more electronegative than Cl atom. Therefore Cl_{2}O is dipolar.

HBr is a strong acid. Therefore it is dissociated completely to give H^{+} and Br^{-}.

Hence an ion-dipole attractive force operates between dipolar Cl_{2}O and H^{+} and Br^{-} ions.

Dichlorine monoxide has the same structure like that of water. So, this is a polar molecule. For polar molecules, the dominant intermolecular force would be dipole-dipole forces. For HBr, there is a force between two oppositely charged ions, H⁺ and Br⁻. So, the dominant intermolecular force is electrostatic attraction.

A sample of oxygen occupied 626 mL when the pressure increased to 874.27 mm Hg. At constant temperature, what volume did the gas
Usimov [2.4K]

Answer:

709 (With sig figs)

Explanation:

Pressure(1) * volume(1) = Pressure(2) * volume(2)

771.75 mm Hg * unknown = 874.27 mm Hg * 626 mL

771.75 mm Hg * unknown = 547,293.02 mm Hg*mL

   Divide both sides by 771.75 mm Hg

Unknown = 709 (With sig figs)....709.158432 (without sig figs)

Si dos elementos tienen igual valor del número cuántico n y diferente l, ml y ms entonces deben estar en : El mismo orbital, per
OlgaM077 [116]

Answer:

El mismo nivel, pero diferente subnivel y orbital

Explanation:

En un átomo, el número cuántico principal n muestra el nivel de energía del electrón.

Si dos electrones tienen el mismo valor del número cuántico principal n, simplemente significa que están en el mismo nivel de energía.

Sin embargo, cuando los números cuánticos l y ml difieren, los electrones deben estar en diferentes subniveles y orbitales.

1 CH4 (g) + 2 O2 (g) -----> CO2 (g) + 2H2O(l) ΔH= - 890 kJ
1 mol           2 mol
1)  If ΔH has minus, it means "release". We need only "release" choices.<span>
2) From reaction
1 mol </span>CH4 (g)  "releases"  ΔH= - 890 kJ  - We do not have this choice.

2 mol  O2 (g)   "release" ΔH= - 890 kJ, so
1 mol  O2 (g)   "release" ΔH= - 445 kJ
Correct answer is B.
