Light passes straight through a solution without scattering. By contrast light passed through a(n) will scatter because the dispersed particles are similar in size to the wavelengths of visible light. This phenomenon is known as the effect and is an important tool in distinguishing between the different types of mixtures.

Astudent carefully transfers 30 g of water and 30 g of alcohol in a glass tube, forming two layers and filling the tube completely. after sealing the tube, the student mixes the solutions, and notices a bubble that forms in the tube. what is the mass of the contents in the glass tube after mixing?

(1.6 × 10-19)(5.0 × 106) = c × 10d identify the missing numbers below to show the result of multiplying the numbers.
