how water gas is obtained from acetic acid?
363106
"Water gas" is a ~1:1 mixture of carbon monoxide and hydrogen that is typically produced by passing water vapor over carbon (e.g., activated charcoal, coal, coke) at a high temperature.  The relevant reaction is:\n\n      H2O + C -> H2 + CO\n\nWhere the products of this reaction constitute "water gas".\n\nNow, note that acetic acid has the formula CH3COOH, which has the same stoichiometry as water gas, implying that it could potentially react to form water gas:\n\n     CH3COOH -> 2CO + 2H2\n\nHowever, at atmospheric pressure and a temperature of ~440C, acetic acid breaks down to form carbon dioxide and methane, not CO and H2:\n\n     CH3COOH -> CO2 + CH4\n\nThe question then is, how does one shift the reaction:\n\n     CO2 + CH4 -> 2CO + 2H2,\n\nto the right?  Given that the volume change for this reaction as written is positive (4 moles of gas as products vs. 2 moles of gas as reactants), and the entropy change must also be positive (by simlar reasoning), higher temperatures and low pressures should favor the products(water gas) over the reactants.  Without having a table of thermodynamic data at elevated temperatures at my fingers, I can't check this, but you can certainly dig up the needed data and check my prediction.

The previous answer is partially correct.\n\nWater reacts with the excess acetic anhydride which is converted to acetic acid.\n\nSince the product is only slightly soluble in water, this also makes it possible to collect the product as a solid.

I'm not exactly sure what you're talking about, but yes, water can be separated into hydrogen gas (H2) and oxygen gas(O2). It's the following redox reaction.\n\nreduction: 2e- + 2H+ + H2O --> H2 + H2O\noxidation: 2H2O --> O2 + 4H+ + 4e-\n\nMultiply the reduction reaction by two and add the two together to get the final reaction.\n\n2H2O --> 2H2 + O2\n\nThe hydrogen goes down from a +1 state to a 0 state, and the oxygen goes up from a -2 state to a 0 state.

For example, hydrogen burns in oxygen to form water vapor. \n\n2H2(g) + O2(g) -> H2O(g) \nHow much hydrogen must be burned to form 1.00 L of water vapor at 1.00 atm pressure and 3000C? \nTo work this problem, we need to figure out how many moles of water vapor we need to form. Use the ideal gas equation to compute this: \n\nPV = nRT \n1.00 atm * 1.00 L = n*0.0821 (L*atm/mol*K)* 473 K \nn = 0.0258 moles \nThus, we need to form 0.0258 moles of water. Now it's just a basic stoichiometry problem: for each mole of water formed, you need 2 moles of hydrogen gas, so 0.0258 moles water * 2 moles H2/1 mole water = 0.0516 moles of hydrogen \n\n=====================================================\n\nthis will help you a lot\n\nhttp://www.chem.hawaii.edu/asato161/Ch10NotesP2.pdf#search='Gas%20Stoichiometry%20PV%3DnRT'\n\nhttp://members.aol.com/profchm/gasstoic.html

Actually, that is a somewhat simplified reaction,\nin reality, the water and Carbon Dioxide dont form directly, they form after a secondary reaction (Carbonic acid decomposing).\n\n3Na2CO3 + 2H3PO4 --> 2Na3PO4 + 3H2CO3\nH2CO3 --> H2O + CO2\n\nSo combining them,\n3Na2CO3 + 2H3PO4 --> 2Na3PO4 + 3H2O + 3CO2

This is what actually happens:\n\nCaCO3 + H2SO4=H20+CO2+CaSO4\n\nIn short, you get carbon dioxide, water and CaSO4. CaSO4 is better known as gypsum:\nhttp://www.galleries.com/minerals/sulfates/gypsum/gypsum.htm\n\nGypsum is used to create plaster of paris.\n\nWhoever said acid rain needs to go back to class.

In general, a gas turns into a liquid by cooling it.

I'll talk through it, since I can't draw structures.  Presumably, this is an acid catalyzed process.  The first step is protonation of the oxygen on acetone.  This creates a more electrophilic carbonyl.  One of the hydroxyls of the starting material will attack the carbonyl carbon, generating a hemiacetal.  Protonation of the hydroxyl of this hemiacetal, followed by elimination of water with assistance from the lone pairs on the neighboring oxygen will generate an oxonium ion suited for another nucleophilic attack by the other hydroxyl of the hydrobenzoin.  A final proton transfer will generate the acetal.

The principal raw materials for acetylene manufacture are calcium carbonate (limestone) and coal. The calcium carbonate is first converted into calcium oxide and the coal into coke, then the two are reacted with each other to form calcium carbide and carbon monoxide:\n\nCaO + 3C → CaC2 + CO \nCalcium carbide (or calcium acetylide) and water are then reacted by any of several methods to produce acetylene and calcium hydroxide.\n\nCaC2 + 2H2O → Ca(OH)2 + C2H2 \nAcetylene can also be manufactured by the partial combustion of methane with oxygen, or by the cracking of hydrocarbons.

It's an acid catalysed hydrolysis. The oxygen attached to the 2-carbon is protonated, then acetic acid is displaced from the ring by water, which is deprotonated to give salicylic acid. The vinegar smell is acetic acid. Note that the reaction cannot occur without water.

Air is composed of eight or so chemical molecues and combines to create a gas. Water is composed of hyrogen and oxygen molecues and exists as a liquid or solid state (ice).  The difference in density of comparing a gas to a liquid is that the gas is less dense than the liquid, therefore offering less resistance to your hand.

Glacial acetic acid is a trivial name for water-free acetic acid. Similar to the German name Eisessig (literally, ice-vinegar), the name comes from the ice-like crystals that form slightly below room temperature at 16.7 °C (about 62 °F).\n\nThe most common and official abbreviation for acetic acid is AcOH or HOAc where Ac stands for the acetyl group CH3−C(=O)−. In the context of acid-base reactions the abbreviation HAc is often used where Ac instead stands for the acetate anion (CH3COO−), although this use is regarded by many as misleading. In either case, the Ac is not to be confused with the abbreviation for the chemical element actinium.\n\nAcetic acid has the empirical formula C2H4O2. This is often written as CH3-COOH, CH3COOH, or CH3CO2H to better reflect its structure. The ion resulting from loss of H+ from acetic acid is the acetate anion. The name acetate can also refer to a salt containing this anion or an ester of acetic acid.

Water is just a liquid gas isn't it? Hydrogen and Oxygen mixed makes water. That's how.

Some tips...\n--Use a strong electrolyte (substances that will break up into ions [almost] completely in solution), the higher the concentration, the better.  Also you need to be careful on which electrolyte you choose.\n--Try not to use an over volttage (a voltage over the minimum necesary to electrolisize the water.  Insread, try to use a very high current, higher current = more production of gasses.  To increase current without increasing voltage, reduce resistance.\n--Place the electrodes close together to reduce internal resistance in the cell.\n\nEven by doing these things, you cannot hope to get much better than about 50% efficency doing water electrolysis, maybe 65% if you are good.\n\nThere are yahoo groups out there devoted to just such a tast as Hydrogen production through water electrolysis (I have one infact), they can also give advice based on experience.
