31. Suspension mixtures have particles that are big enough to settle at the bottom. * 1 point TRUE FALSE 32. Colloids are composed of molecules bigger than a solution but smaller than a suspension. * 1 point TRUE FALSE 33. Colloids are homogeneous mixture. * 1 point TRUE FALSE 34. The dispersed particles in a suspension mixture do not dissolve completely in a suspension medium. * 1 point TRUE FALSE 35. Ketchup is an example of a suspension. * 1 point TRUE FALSE 36. Suspension is a heterogeneous mixture in which solute particles of the dispersed ingredients are not really dissolved in the liquid but settle later on or at the bottom of the container. * 1 point TRUE FALSE 37. Brownian motion is the motion of the tiny particles in colloid. * 1 point True False 38. Tyndall effect is the effect of light scattering in colloidal dispersion. * 1 point TRUE FALSE 39. When no light is shown in a mixture, that is suspension. * 1 point TRUE FALSE 40. In solution, the beam of light is visible and scattered. * 1 point TRUE FALSE
