What is the magnitude of the electrostatic force between a singly charged sodium ion and an adjacent singly charged chlorine ion
Arisa [49]
To know the electrostatic force between two charges or between two ions, you can use the Coulomb's Law. The equation is F = k*q1*q1/r^2, where F is the electrostatic force, q1 and q2 are the charger for Na and Cl, and r is the distance between the centers of both atoms. In literature, the distance is 0.5 nm or 0.5 x 10^-9 meters. The charge for Na+ and Cl- is the same magnitude but different in sign. Since Na+ is a cation, its charge is +1.603x10^-19 C (the charge of an electron). For Cl- being an anion, its charge is -1.603x10^-19 C. The constant k is an empirical value equal to 9x10^9. Using the formula:

F = (9x10^9)(+1.603x10^-19)(-1.603x10^-19)/(0.5 x 10^-9)^2
F = -9.25 x 10^-10 Newtons

The negative denotes that the net force is more towards the Cl- ion.

What is the difference between a polar and a nonpolar bond?And how can i figure out if its polar or nonpolar in a bond question?
ra1l [238]

Answer:

If the electronegativity of two atoms is basically the same, a nonpolar covalent bond will form, and if the electronegativity is slightly different, a polar covalent bond will form.

Explanation:

that's your answer very easy.

What is the relationship between radio waves and motion?
eimsori [14]

Answer:

Radio waves are a type of electromagnetic radiation and they use it for communication for things like phones,computers, and just mobile devices.

An object in motion, will remain at a constant velocity unless an unbalanced force comes upon it and that is a proven fact.
