I need an example of what Suspension is in Biology/Chemistry.?
Q. Suspension is when a certain substance is mixed with a fluid. The particles of that substance will float throughout the liquid and will not dissolve, quickly. Please, please, please help! I need an example of this for my homework and I can't think of one!

A. Liquid cleansers are abrasives (silica or alumina) suspended in soaps and water. Blood is a suspension of cells in serum. Colloids are suspensions of particles that are so fine that they never settle out. They look cloudy. I think milk is a suspension/colloid.

A. "In chemistry, a suspension is a heterogenous fluid containing solid particles that are sufficiently large for sedimentation. " Mud or muddy water, is where soil, clay, or silt particles are suspended in water. Flour suspended water Paint Chalk powder suspended in water. Dust particles suspended in air. juice w/ pulp italian dressing sea salt in the air from crashing ocean waves clouds, fog Sulfates occur as microscopic particles (aerosols) resulting from fossil fuel and biomass combustion.

Q. 1)what are emulsion and suspension want examples too. 2)what are similarities between compounds and mixtures? 3)what happens when you put mercury in a beaker full of olive oil? 4)how would you measure the exact volume of sand? 5)the dust of a carpet is obsorbed by a vacuum cleaner.How can the dust particles be seperated from the air?

A. 1.) an emulsion is a colloid made up of two substances that don't normally mix, which are binded together by an emulsifier (like oil and water bound together by soap). A suspension is any heterogenous mixture made up large particles. (an example would be mud) 2.) compounds and mixtures are both made up of two or more different substances. 3.) The mercury would likely form little mercury orbs floating in the oil. 4.) Place the sand in a graduated cylinder or any measuring glassware that has some water in it. Subtract the final volume of the water from the initial and that is the volume of the sand. 5.) Use an adsorptive surface (like a charcoal filter). The dust should stick to the surface of the filter.

Take a bite, wait and watch the color of the inside turn a little brown. That's oxidation 8. beads in water, then filter out the water 9. sand and pennies. Use wire to sieve out the pennies, or pennies and water and boil off the water 10. A toy where a clown hits something and makes noise takes kinetic energy… [cont.]

A. Toluene is not soluble is water. Because the molecules are so different they do not mix. Hydrocarbons and water do not mix. They will only mix if you put a functional group on that will be similar to water, e.g. caboxylic acid group will help.
