A. honey or heavy syrup is viscous liquid liquid would be a combination of rubbing alcohol and water. you can get rubbing alcohol at any drug store or convenience store. just ask for "70% isopropyl alcohol" gaseous liquid solution would be carbonated drink, like seltzer or mineral water

How is the concentration of CO2 dissolved in a liquid measured?
Q. CO2 is dissolved in a solution by some dipole-dipole interactions, and also by acid-base reactions between the slightly acidic CO2 molecule/ neutral water... So, when you see CO2 measurements in L/L or % volume/volume, what is this number actually measuring? The volume/volume of the gaseous CO2 phase with liquid water? Or CO2 in the aqueous phase and liquid water?
Asked by Rasha S - Mon Jul 21 16:42:38 2008 - - 1 Answers - 0 Comments

A. Carbon dioxide concentrations, and other gases as well, are usually measured in solutions by gas chromatography. The chromatograph is usually equipped with a thermal conductivity detector, which can detect most materials. Concentration units are the same as any other solution, although I agree a v/v ratio concentration unit is not too useful.

Are the engines running on gaseous hydrogen?
Q. I am wondering if there are engines that run on hydrogen, but not in liquid, but in gaseous form?! I do not ask weather or not this is possible, but if it exists! If it doesn't, are existing hydrogen engines easily adaptable to that? This is the situation: You have balloon of hydrogen, let's say at approximately 1.5 to 3.0 bar. This gas is directly to be used for power generation in an engine. Running it through a big an heavy compressor is impossible. Note: Heavy weight solution are not practicable.

This gas is directly to be used for power generation in an engine. Running it through a big an heavy compressor is impossible. Note: Heavy weight solution are not practicable." That's quoted from your own Question. So am I to assume that your fuel source--the hydrogen--is also going to be a source of bouyant lift, as per an airship? Because if that is the case, some obvious things immediately come to mind: --You are going to lose lift rather quickly as your fuel is used up.

A. Some solids, when added to a liquid, appear to disappear. There are everyday examples of this: salt in a boiling pan of vegetables, sugar in tea of coffee. The solid doesn't disappear, it dissolves and forms a solution, but how can this be proved? A simple understanding of evaporation and condensation is required. When a liquid reaches its boiling point, it evaporates forming a gas. When the gas cools, it condenses, reforming into a liquid. This is called a physical, rather than a chemical change. So, how do we prove that a solid, dissolved into a liquid doesn't just disappear or evaporate with the liquid? You will need an old clean pan, a clean hand mirror, a pair of gloves and some salt Cover the bottom of the pan with about 2cm of… [cont.]

A. Unless this is a meant to be a tricky question... Well, quick answer is B. carbon dioxide reacts with water unlike oxygen. It gets converted into carbonic acid, which, theoretically is a liquid. So, it is liquid in liquid. For a five hundred dollars, that is my final answer (ever watched who wants to be a millioner?). But, remember, if you can convince me that carbonic acid can be seen as still CO2 molecules (I just can't see it that way), then the answer can be A (solute and solvent definitions assume solvent is higher in volume but if this was for a million dollars, I would think about this answer also, pretty hard). And reading the previous answer, if you still think it is gaseous CO2 and don't like option A, then, yes, is none of the… [cont.]
