When is a mixture not a solution?
409824
When what is mixed is not fully disolved into the liquid medium.  It usually settles.  A cenrifuge will not separate out the components that are not part of the solution.

milk is a mixture \ncopper is an element

compound is a mixture of 2 differ net elements. homogeneous mixture of 2 or more substances that keep their identifies. therefore they are similar in that they are mixture of two or more diffident substances, but different in that the homogeneous mixture has the substances that keep their identifies. Homogeneous mixtures are also called solutions because u cannot identify their ingredients like in a compound.

man you can't balance an equation if there is none and HCL is not an equation

blueb_24' s answer to the first part of you question is great. \n\nMechanical mixtures are very simple mixtures that can be separated mechanically (soap is definitely not one). Some mechanical mixtures found in everyday life: \n- M&M's (various colours)\n- Mixed vegies\n- Bag of marbles\n- Box of bolts and nuts\n\nSolutions are more complex and can only be seperated by means of their physical properties, such as boiling point. Some everyday solutions include:\n- Coffee\n- Detergent\n- Salt water\n- Vinager\n\n4.a  Solid solutions: \n- Sand - suspension mixture of solid particles\n- Muddy water - solid particles suspended in water\n- Smoke - solid mixed in gas\n\nb) a liquid solution that does not contain water:\n- Motor oil - a mixture of heavy hydrocarbons\n- Vegetable oil - mixture of plant oils\n\nc) a solution of gases\n- Air - air is a mixture of many gases\n- LP gas (liquid petroleum gas)- mixture containing mainly propane or butane (depending on application)

A pure substance can be a chemical combo of two elements. So if you know chemistry, and you think about all the possible combos there are, there are quite a few million out there.

Hey I'm studying physical and chemical equilibrium too, currently.The answer is that it will definitely have units when the concentrations have different powers.Just try and work it out with the units and it will be very clear.

A mixture is things mixed together but not completely so you can tell them apart. Eg: Sand and Flour. A solution is something that once you mix it together, you can no longer tell the two things apart. Eg: Salt and Water. I would have to say that the cake would be a solution after it is baked because you can no longer tell the different ingredients apart. (If it was made correctly.)

The response depends on what you call "not concentrated".  Any saturated solution, as you correctly indicate contains the maximum amount of solute at a specific temperature.  \n\nIf by "not concentrated" you mean that the maximum is low (compared to what?) then you can find sparingly soluble salts that reach saturation at relatively low concentrations (compared, for example, to NaCl).  The absolute value of these concentrations will be very much lower than the saturation level of NaCl.

wow, well put mrjeffy! I have one thing to add though. Because all acids and bases are electrolytes, you can use pH to determine what is and isn't an electrolyte in a solution. If it come out as acidic or basic, it is and electrolyte(the darker, the more basic or acidic). If it comes out neutral, like Distilled Water, it is not. Also don't forget that non-electrolytes will not completely dissolve into solution in water.

A mixture is made up of different kinds of particles. You can separate mixtures into their different particles.\n\nA pure substance is made up of one kind of particle. Pure substance are classified as either an element or a compound.\n\nMixtures are then classified into heterogeneous mixtures (where you can see different kinds of particles with your own eyes... ie. sand in water, dirt) or homogeneous mixtures (aka solutions) (where you cannot see different kinds of particles... ie. sugar mixed in water).

I agree with the first poster on C and E, but I'm not sure if A is also.  A solute dissolving in a solvent seems like a chemical process to me, but I don't remember for sure.

not too much, they are both basic, and don't really react. even if it is an aqueous solution of ammonia (thus avoiding the gas problem above)

C because the solution is SATURATED with solute, meaning no more solute can be dissolved by the solvent in the solution.

Unless a equation is properly balanced the amount of product and reactant will not be the same, I suppose this is like a recipe where u get the proper number of ingredients(moles) and mix to together to give the you the proper number of products.

Different chemical composition, one has a reaction the other doesn't..☺

(m)\n\nA mixture of two or more substances that cannot be easily separated by common physical means (ie settling, filtration, etc.). A mixture with no visible separation between its components. For example, salt and water. Compare to heterogeneous mixture.
