Identify the molecule with the strongest intermolecular force HF HCl Hl HBr

1 answer:

6 0

Hey there !:

HF s molecule with the strongest intermolecular force

<span>HF > HI > HBr > HCl</span><span>

</span>The main factor of influence at the boiling point is the question of intermolecular forces, but not only that, the molar mass also has influence (the greater the molar mass, the greater the boiling point). Note that the only one forming hydrogen bridges is the HF, therefore the largest boiling point, iodine, bromine and chlorine have the same type of intermolecular (permanent dipole) connections as they are polar, and what will differentiate the boiling point of each one is the molar mass.

Which statement describes why sodium reacts more vigorously than magnesium to hydrochloric acid? Refer to the periodic table. Ci

lions [1.4K]

Sodium has a lower ionization energy than magnesium describes why sodium reacts vigorously than magnesium chloride.

<h3>Why is sodium more reactive than magnesium?</h3>

Sodium is more reactive than magnesium because it has the ability to easily lose electron, hence have lower ionization energy.
Sodium belong to group one on the periodic table and they are called akali metal while magnesium belong to group two on the periodic table and they are called alkali Earth metal.

Sodium and magnesium belong to the in the 3rd period. Iin the outermost energy level sodium has one electron but magnesium has 2 electrons. Therefore, there is more attraction abetween the nucleus and electrons in magnesium than that of sodium.

Therefore, sodium is more reactive than magnesium chloride because of lower ionization energy.

What is the correct coefficient for Fe2O3 in the balanced version of the following equation?

Ipatiy [6.2K]

Answer:

The coefficient of Fe₂O₃ is 1

Explanation:

__Fe₂O₃ + 3H₂ —> 2Fe + 3H₂O

To know the correct coefficient of Fe₂O₃, we shall balanced the equation. This can be obtained as follow:

Fe₂O₃ + H₂ —> Fe + H₂O

There are 2 atoms of Fe on the left side and 1 atom on right side. It can be balance by writing 2 before Fe as shown below:

Fe₂O₃ + H₂ —> 2Fe + H₂O

There are 3 atoms of O on the left side and 1 atom on the right side. It can be balance by writing 3 before H₂O as shown below:

Fe₂O₃ + H₂ —> 2Fe + 3H₂O

There are 2 atoms of H on the left side and 6 atoms on the right side. It can be balance by writing 3 before H₂ as shown below:

Fe₂O₃ + 3H₂ —> 2Fe + 3H₂O

Now, the equation is balanced.

Thus, the coefficient of Fe₂O₃ is 1

How many atoms are in 3.0 moles of NA?

Vanyuwa [196]

Avogadro's number is the number of atoms in one mole of a substance. The number is 6.022 x 10^23 atoms/mol. So, if you have 1 mole of carbon atoms, there will be 6.022 x 10^23 atoms in that sample.

Hope this helps
