How do chemists predict the shapes of molecules?

Chemists can't predict the shape of molecules, because the attractive forces between valence electrons are unpredictable.

Answer:

Yes, it is possible because they have similar intensive properties.

homogeneous mixture

Due to the repulsion between electrons, valence electrons will be arranged as far apart from each other as possible.

Neutral atoms of lead must have 82 protons. Ions must have 82 protons, as well.

Experiments that identified characteristics of atoms provided scientists with atomic weights and atomic numbers, which were used to organize the periodic table.

A covalent bond would form because the electron would be shared so both hydrogens have a full, stable shell.

K and Cl

Polar sugar molecules dissolve in water, which is polar.

High temperatures mean more kinetic energy, which keeps sodium and chlorine ions from combining, which increases solubility.

It accepts protons and only partially dissociates in water.

PH3 is a stronger acid than NH3.

The scientist is investigating Charles’s law, which shows that temperature and volume are directly proportional.

It will likely be unreactive.

Student B, because of the law of conservation of matter.

The atoms have the same electronegativity.

bromine (Br)

No, it will not because iodine is less reactive than chlorine.

6H2O + 6CO2 → C6H12O6 + 6O2

+2

0.24 M

Tungsten (W) changes oxidation numbers from +6 to zero, so it undergoes reduction.

It has a higher boiling point than water, and it likely has stronger electrostatic forces between its molecules than water.

castor oil

Substance B has stronger bonds, and it takes more energy to undergo a phase change.

The student should perform multiple trials of the same experiment, then take the average of all of the results.

The results of several trials are all very close to each other, but they are noticeably different from the accepted value for the boiling point.
