Final answer:
The magnitude of the attractive force between two adjacent sodium and chloride ions can be calculated using Coulomb's law. The equation for the magnitude of the force is F = k * (Q1 * Q2) / r^2, where F is the force, k is the electrostatic constant, Q1 and Q2 are the charges of the ions, and r is the distance between them. Plugging in the values for the charges and distance will allow you to calculate the magnitude of the force.
Step-by-step explanation:
The magnitude of the attractive force between two adjacent sodium and chloride ions can be calculated using Coulomb's law. According to Coulomb's law, the force between two point charges is directly proportional to the product of their charges and inversely proportional to the square of the distance between them.
The magnitude of the attractive force between two adjacent ions can be calculated using the equation:
F = k * (Q1 * Q2) / r^2
Where:
- F is the magnitude of the force
- k is the electrostatic constant, approximately equal to 9 x 10^9 Nm^2/C^2
- Q1 and Q2 are the charges of the two ions
- r is the distance between the ions
In this case, the sodium ion has a charge of +1 and the chloride ion has a charge of -1. The distance between the ions is given as 0.28 nm. Plugging these values into the equation:
F = (9 x 10^9 Nm^2/C^2) * (1 * -1) / (0.28 nm)^2
Calculating this expression will give you the magnitude of the attractive force between the two adjacent ions.
