What are some examples of compounds?PLEASE HELP?
Q. I need to no this by friday. Also I need examples of elements, mixtures, solutions, suspension, and colloid. thanks for the help. Also i did listen in school, i am home schooled and i needed to know ten of each, so it was hard, i still don't have 10 of each though, also we are not allowed to use the ones she put in the examples

A. 1. Compounds. Hexane, carbon dioxide, water 2. elements. hydrogen, nickel, copper 3. mixtures include all solutions, suspensions and colloids. 4. Solutions are salt water, sugar dissolved in water. 5. Suspensions are muddy water, Ocean water. Anything that has the particles settle on the bottom. The particles in suspensions are larger than 10^-7 meters 6. Colloids are like milk, toothpaste, jelly, blood. The particles do not settle on the bottom and you cannot see them without a microscope. They are in between 10^-9 and 10^-7 meters size you should have learned this in school. You were probably goofing off in class when the teacher was talking.

how can colloids be heterogenous mixture?
Q. example of collids are clouds, hair gel etc. It has only one part to be visible like homogeneous right? So why is it in my text book that colloids are heterogeneous?
Asked by Jenny - Fri Sep 25 00:23:45 2009 - - 2 Answers - 0 Comments
A. The quick and easy answer is the particle size dispersed in the medium and the appearance. A colloid has particles sizes that are between a homogeneous and a heterogeneous mixture. The appearance of the colloid determines whether the colloid is considered homogeneous or heterogeneous. Mayonnaise is has a homogeneous appearance. Milk can have a homogeneous appearance or, if the butterfat particles have not been broken down, can appear heterogeneous. (milk is a colloidal mixture of liquid butter fat suspended in a water based liquid)

Asked by moonhee - Sun Jun 10 22:12:15 2007 - - 1 Answers - 0 Comments
A. Solution: something (a solute) has been dissolved in something else (a solvent) - for example salt (the solute) dissolves in water (the solvent) Solubility: how easy it is for the solute can be dissolved into the solvent - for example salt is very soluble in water while sand is not Suspension: one substance is put into another but remains separate from it - for example when fruit is mixed with jello it is suspended - also in wet cement the aggregate (sand or gravel) is suspended in the mixture It's been 23 years since I taught science & I'm afraid I can't remember the exact definition of the rest - good luck.
