aev [14]

Answer:Given data from the lab collated as 291.15k for Temperature, 0.061L for volume and 1atm pressure.

Initial hydrogen peroxide solution is 5ml with a weigh % concentration 6.6%

n=0.0025moles of oxygen AND 0.0097moles of H2O2 were present

Explanation:

2H2O2(aq)-----2H2O(I)+2O2(g)

Recall the idea gas equation

PV=nRT

n=PV/RT---(1) solving equation (1) using the data in the answer section above.

n=0.0025moles of oxygen is produced.

Recall that for every 100ml of solution you get 6.6g of hydrogen peroxide.

Your 5ml will thus contain

5ml*6.6g H2O2/100ml=0.33g

no of moles if H2O2=0.33/34.015=0.0097moles

On the basis of molecular structure and bond polarity, which of the following compounds is most likely to have the greatest solu

Drupady [299]

Answer:

$\boxed{\text{c) NH$_{3}$; hydrogen bonding}}$

Explanation:

For each of these molecules, you must determine their VSEPR structure and then identify the strongest intermolecular forces.

Remember that water is a highly polar molecule.

a) CH₄

Electron geometry: tetrahedral

Molecular geometry: tetrahedral

Bond polarity: C-H bond nonpolar

Molecular polarity: nonpolar

Strongest IMF: London dispersion forces

Solubility in water: low

A nonpolar molecule is insoluble in a polar solvent.

b) CCl₄

Electron geometry: tetrahedral

Molecular geometry: tetrahedral

Bond polarity: C-Cl bond nonpolar

Molecular polarity: nonpolar (symmetrical molecule. All bond dipoles cancel)

Strongest IMF: London dispersion forces

Solubility in water: low

A nonpolar molecule is insoluble in a polar solvent.

d) PH₃

Electron geometry: tetrahedral

Molecular geometry: trigonal pyramidal

Bond polarity: P-H bonds are polar

Molecular polarity: polar (all P-H bond dipoles point towards P)

Strongest IMF: dipole-dipole

Solubility in water: soluble

A polar molecule is soluble in a polar solvent.

c) NH₃

Electron geometry: tetrahedral

Molecular geometry: trigonal pyramidal

Bond polarity: N-H bonds are highly polar

Molecular polarity: highly polar (all N-H bond dipoles point towards N)

Strongest IMF: hydrogen bonding

Solubility in water: highly soluble

NH₃ is so polar that it can form hydrogen bonds with water.

$\boxed{\textbf{The compound with the greatest solubility in water is NH$_{3}$}}$
