Question

calculate the electrostatic force of attraction between a proton and an electron separated by a distance of 8x10^-14m​

Answer 1

$F = \frac{k q1 q2}{r^{2}}$ $= \frac{9*10^{9}*1.6*10^{-19}*1.6*10^{-19}}{8*10^{-14}} = 2.88*10^{-15}$

A solution is defined as a:

A .

Homogeneous mixture of two or more substances

B .

Heterogeneous mixture of two or more substances

C .

Homogeneous mixture of liquid and solid components only

D .

Homogeneous mixture consisting of water as one of

A solution is a homogeneous mixture of two or more substances. A solution may exist in any phase. 

A solution consists of a solute and a solvent. 

The solute is the substance that is dissolved in the solvent.

For example, in a saline solution, salt is the solute dissolved in water as the solvent.
