How many moles of ammonium ions are in 6.965 of ammonium carbonate?
As the formula for ammonium carbonate is (NH4)2CO3, there are two moles of ammonium for every mole of ammonium carbonate. Just double the given number.
What was given off when ammonium chloride was heated?
since ammonium chloride is a subline solid, it gets converted into gaseous state directly without changing into liquid state
When Calcium carbonate is heated .?
It decomposes into calcium oxide and carbon dioxide...
What is the balanced equation for ammonium carbonate?
Ammonium carbonate, (NH4)2CO3 dissolves in water releasing the ammonium ion, NH4+, and carbonate ion, CO32- into solution. Both of these ions hydrolyze (react with water). The chemical equations describing the hydrolysis reactions are given. By adding these reactions one can write the overall balanced net ionic equation for the reaction that occurs when ammonium carbonate dissolves in water. Write the overall balanced net ionic equation, calculate the equilibrium constant, write the overall equilibrium expression, and calculate the carbonate ion concentration, [CO32-], of a 1.0 mol/L solution of ammonium carbonate. (Hint: this requires solving a quadratic equation)... --Equations (1) (NH4)2CO2 (aq) --> 2NH2+ + CO32- (2) NH2+ + H2O(l) <--> NH2(aq) + H2O+ Ka=5.6x10-10 (3) CO32- + H2O(l) <--> HCO3- + OH- Kb=2.1x10-4
Why iron corroded in the presence of ammonium carbamate?
Ammonium carbamate is a chemical salt resulting from the reaction of ammonia and carbon dioxide. The structure is: H2N-C(=O)-O(-)(+)NH4. Ammonium carbamate can be formed without any intermediates by passing ammonia gas over solid carbon dioxide (dry ice). In the real world, there is often water present and this complicates matters. Carbon dioxide and water can react to form carbonic acid, H2CO3. Carbonic acid is a diprotic acid and can react with 2 equivalents of base, so, when carbonic acid reacts with ammonia, ammonium bicarbonate begins to form; HO-C(=O)-O(-)(+)NH4. As more ammonia is added, ammomium carbonate begins to form; H4N(+)(-)O-C(=O)-O(-)(+)NH4. These are equilibrium reactions. As the concentration of ammonium carbonate increases, there is a conversion of some of the ammonium carbonate to ammonium carbamate. This is a dehydration reaction. An industrially important chemical that is derived from ammonia and carbon dioxide is urea, which is used as fertilizer. Urea is ammonium carbonate that has given up two molecules of water; H2N-C(=O)-NH2. The fertilizer plants that manufacture urea have severe corrosion problems due to the ammonium carbamate intermediate. The corrosion is so severe that carbon steel cannot be used. Some parts of the process will corrode 316 stainless steel. Those heated sections are manufactured from special alloys. Why does iron corrode in the presence of ammonium carbamate? Ammomium carbamate is hygroscopic and will attract moisture. Wetted ammonium carbamate will become an equilibrium mixture of ammonium carbamate and ammonium carbonate. This combination of salts and moisture attacks the protective oxide layer on the surface of steel with chelation-type mechanism. This exposes the underlying base metal for further attack.

What is the chemical change in baking soda?
Baking Soda is Sodium hydrogen carbonate(NaHCO3). When heat is given, it decomposes into Sodium carbonate(Na2CO3), Steam(H2O) and Carbon dioxide(CO2), according to the following equation:2 NaHCO3 --Δ--> Na2CO3 + H2O + CO2

Why should you use sublimation to separate the mixture of salt and ammonium chloride?
Because ammonium chloride can be removed from salt by sublimation (at a given temperature).
