How much heat is transferred when 7.19 grams of H2 reacts with excess nitrogen, according to the following equation: N2(g) + 3 H2 (g) --> 2 NH3 (g) \DeltaΔH = +46.2 kJ

Answers

Answer:

$Q=54.8kJ$

Explanation:

Hello there!

In this case, according to the given chemical reaction, it is possible for us to realize that the 46.2 kJ of energy are given per mole of reaction, which are related to 3 moles of hydrogen; Thus, we can calculate the energy per mole of hydrogen as shown below:

$\Delta H=(46.2kJ)/(mol) *(1mol)/(3molH_2)\n\n \Delta H=15.4(kJ)/(molH_2)$

Now, to calculate the total energy, we convert the grams to moles of hydrogen as shown below:

$Q=7.19gH_2*(1molH_2)/(2.02gmolH_2)*15.4(kJ)/(molH_2) \n\nQ=54.8kJ$

Best regards!

Problem Page What kind of intermolecular forces act between a hydrogen peroxide molecule and an iron(III) cation? Note: If there is more than one type of intermolecular force that acts, be sure to list them all, with a comma between the name of each force.

Answers

Answer:

H20

Explanation:

peroxide would also eat bacteria along with the water

Final answer:

The primary intermolecular forces which act between a molecule of hydrogen peroxide (H2O2) and an iron(III) cation (Fe3+) are ion-dipole attractions. These arise due to the polar nature of the H2O2 molecule and the charged state of the Fe3+ ion.

Explanation:

The kind of intermolecular forces that act between a hydrogen peroxide molecule and an iron(III) cation chiefly involve ion-dipole attractions, which are a type of intermolecular force. This occurs due to the polar nature of the hydrogen peroxide molecule (H2O2) and the charged iron(III) ion (Fe3+).

The O-H bonds in the hydrogen peroxide molecule are polar as oxygen exhibits a higher electronegativity than hydrogen, meaning that it has a tendency to draw electrons closer to itself. This results in a dipole with partial negative charge residing at the oxygen end of the molecule, and a partial positive charge at the hydrogen end. Meanwhile, the iron(III) ion has a positive charge. This makes for a strong ion-dipole interaction between the two.

It's important to remember that intermolecular forces are the attractions between molecules which are crucial to their physical properties, while intramolecular forces are those that keep a single molecule intact. Further, although the term 'hydrogen bond' may suggest a bond between hydrogen and other atoms, it is, in fact, an intermolecular attraction force which is stronger than others like dipole-dipole attractions and dispersion forces.
