The strongest intermolecular force is the hydrogen bond in water (H2O).
What is intermolecular force?
Intermolecular forces are those that develop between the molecules of a substance and can cause them to attract or repel one another. The type of intermolecular force that is present in the matter determines all of the material's physical and chemical properties.
Interactions between dipoles
Involvements of Ion-Dipoles
Dipole Interactions Induced by Ions
DID Interaction: Dipole Induced DID
London Forces or Dispersion Forces
These five intermolecular force types are listed above.
The intermolecular forces were in this order:
The strongest force is ion-dipole force.
the hydrogen bond
Force between dipoles
the least powerful is the dispersion force.
The strongest intermolecular force is therefore the hydrogen bond in H2O.

Answer:
810 pm
Explanation:
Step 1: Given and required data
- Velocity of the atom (v): 490 m/s
- Mass of a hydrogen atom (m): 1.67 × 10⁻²⁷ kg
- Planck's constant (h): 6.63 × 10⁻³⁴ J.s
Step 2: Calculate the de Broglie wavelength of the hydrogen atom
We will use de Broglie's equation.
λ = h / m × v
λ = 6.63 × 10⁻³⁴ J.s / 1.67 × 10⁻²⁷ kg × 490 m/s = 8.10 × 10⁻¹⁰ m
Step 3: Convert 8.10 × 10⁻¹⁰ m to picometers
We will use the conversion factor 1 m = 10¹² pm.
8.10 × 10⁻¹⁰ m × 10¹² pm/1 m = 810 pm
Answer:
you need only one independent variable because if not, you wont know what factors have changed your experiment.
Explanation:
The percentage error is the error of the measured value to the true value. To find he percent error, the equation is as follows:
Percent error = |Measured Value - True Value|/True Value * 100
The || is needed to get the absolute value of the difference. Substituting the values,
Percent error = |(10.085 g/10 mL) - 0.9975 g/mL|/<span>0.9975 g/mL * 100
</span><em>Percent error = 1.1% </em>
