Do KCl solve in Ethanol?

Potassium Chloride (KCl) has a solubility of .4 g/mL in Ethanol (at room 25 C I would assume), yes, it does dissolve, but barely.

The energy produced by burning Ethanol would be classified as chemical energy, if that is what you are asking.

According to the MSDS for KCl,\nits solubility at 0 degrees C is 28.1 g/100 g of water

In synthetic organic chemistry, water free ethanol can  be produced by adding elementary sodium wire under a nitrogen atmosphere. The sodium will react with water forming NaOH and with the ethanol forming sodium ethanolate, which in turn would react with any water that should make its way into the liquid.\n\nTo remove the salts, you can distill in a water free environment.\n\nSodium wire is highly inflammable. You won't be able to get it outside of laboratories, for a good reason.

To perform a solution-based separation, you need a solvent in which one or some of the solutes (in the mixture to be separated) is/are highly soluble, and in which the other components are highly insoluble.\n\nA simple example might be separating an ethanol/pentane mixture by using water.  Ethanol, being polar, will readily dissolve in water; but the nonpolar pentane will not.

KMnO4 is an oxidizing agent.\n\nit will turn ethanol into ethanal (or acetylaldehyde).  if there is a great excess of potassium permanganate, it will turn ethanal into ethanoic acid (or acetic acid).\n\nbasically, both steps involve decreasing the number of bonds from carbon to hydrogen and increasing the number of bonds from carbon to oxygen.

At 10°C, saturated solution of potassium chloride is more concentrated than potassium nitrate. At this temperature, potassium chloride completely dissolves while potassium nitrate would form some precipitates. At 60°C, it would be the same since both would completely dissolve at this temperature.

ok i will TRY to help you. im not completely sure but i think i know what to do. basically, when you add K2Cr2O7, it splits up into 2 parts, the Ks and the Cr2O7s. the Cr2O7s react with the potassium dichromate and make products. so if it was titrated correctly (assume it is), then \n8.76mL * 1L/1000mL * 0.04988mol/L    mols were added\n= 0.0004369488 mol of Cr2O7 added. and this amount made all the potassium dichromate get used up (apparently).\nwhich means that 0.0004369488/2 mols of potassium were in the blood. (divided by 2 because for each mol of potassium, 2 mols of Cr2O7 were used). so 0.0002184744 mols of potassium were in the blood. and if you use the molar mass to convert that to a mass. and then divide it by 10.0002g. you should get the mass percent of blood alcohol. so 0.0002184744mol x [(2x12.01) + (4x1.01) + (1x16) + (1x1.01)]\n= 0.0002184744mol x 45.07 g/mol\n= 0.009846641208 g  and divide it by 10g to get the mass percent which is 0.098466%.\nhope this helps. let me know if u need more help. laterz

I think A and D are both true.  Because parafin is nonpolar, it should be soluble in a non-polar solvent.  Likewise, because ethanol is polar, it should be more soluble in a polar solvent that in a non-polar one.  Both of these go along with the idea that "like dissolves like".

Ethanol relaxes the DNA, making it leave its partner, much like the effect it has on humans...\n\nJust kidding

Traditional gasoline formulations (i.e., those that do not contain ethanol) are almost completely immiscible in water, and vice versa.  That is, water has very limited solubility in gasoline, and gasoline has very limited solubility in water.  (The addition of ethanol to gasoline significantly increases the solubility of water in the gasoline, though.)\n\nAssuming "traditional" gasoline, and assuming zero mutual solubility, we can easily solve your problem.  \n\nWater has a density of ~ 1 gram/cm^3, so 50 grams of water occupies 50 cm^3.  Gasoline has a density of 0.73 gm/cm^3, so 50 gms of gasoline occupies 50/0.73 = 68.5 cm^3.  The total volume of the system is therefore 50+68.5 = 118.5 cm^3.  The total system has a mass of 100 grams so the average density is 100 grams/118.5 cm^3 = 0.844 gm/cm^3.\n\n[Note added after several people have responded with incorrect answers.\n\nThe answerers who have simply averaged the densities of gasoline and water are incorrect.  If the problem asked for the density of a mixture of equal *volumes* of gas and water, then you could simply average the densities of the individual fluids.  This is not what is being asked, though.  The question asks for the density of a mixture of equal *masses* of gas and water.  Equal masses of gasoline and water do not occupy equal volumes (obviously, because they don't have the same densities).  TO solve the problem, one must first find the volumes occupied by 50 grams of each fluid, then divide 100 grams (the total mass of the system) by sum of the two volumes.]

Ethanol has a low flash point (-5 C), which is the temperature at which enough vapors in the air can be present to create an explosive atmosphere; a spark or flame can cause an explosion.  It also does burn with a weakly colored flame, making it hard to see.  \nAlso - high-strength ethanol that you can by is called denatured alcohol - there are many kinds, but they are all poisoned with something - methanol, isopropanol, toluene etc. which render it undrinkable.  Don't do it.\nPunch in "MSDS" and "ethanol" into yahoo and pull up a material safety data sheet.
