What substance is heated to form a gas mixture

It is the pyrolysis of ammonium bicarbonate.

I really can't figure out if there's something wrong with the question.

But I can give you a little idea.

I know that hydrogen sulfide can react with concentrated sulfuric acid.

Sulfur dioxide is generated.

Small amounts of magnesium can be re-burned in sulphur dioxide.

Magnesium oxide, with sulfur, is generated.

But sulfur reacts with concentrated nitric acid.

Sulfur dioxide is generated.

Sulphur dioxide can react with sulphuric acid again (check the information).

Produces even disulfuric acid.

At first, it was not known how hydrogen sulfide was obtained by the decomposition of a substance.

NH4Cl heating = NH3 + HCl

2NH3+3H2SO4 concentration = N2+3SO2+6H2O, with the reaction, concentrated sulfuric acid thins, there will be no strong oxidation, 2NH3+H2SO4=(NH3)2SO4+2H2O

so2+h20=h2so3

h2so3+o2=h2so4

N2 and H2SO4 and H20 are all pre-existent.

So the new substance after persulfuric acid is (NH3)2SO4

mg+O2=mgo mgo+H2O=mg(OH)2HCl+mg(OH)2=mgCl2+H2OMGCl2+Hno3 concentrated = NO2+H20+mg(NO3)2+Cl2

Concentrated sulfuric acid is supposed to be used to remove a certain gas, right?

Aluminum sulfate and sodium bicarbonate solution, the two solutions are mixed together, and a large amount of carbon dioxide gas will be produced.

The principle of buried brigade fire extinguishing of chemical foam fire extinguisher, the equation is as follows: Al2(SO4)3+6NaHCO3==3Na2SO4+2AL(OH)3 +6CO2

In fact, it is toilet cleaner and 84 disinfectant. Matching.

The reason is: 84 disinfectant contains sodium hypochlorite Naclo, and the toilet cleaner contains a higher concentration of HCl hydrochloride, which will be neutralized under the acidic strips after mixing, so that a large amount of chlorine gas escapes, and if the two detergents are used incorrectly, it may cause death.

hclohcl

Cl2H2O, note the gas symbol of chlorine, this reaction is carried out under acidic conditions.

Typical examples are ammonium carbonate ((NH4)2CO3), ammonium bicarbonate (NH4HCO3) and ammonium nitrate (NH4NO3). The first two pyrolysis produces ammonia, water vapor and carbon dioxide, and the latter produces ammonia and water vapor as well as nitrogen dioxide from the decomposition of nitric acid.

NH4HCO3 ammonium bicarbonate is heated to produce ammonia, water (vapor) and carbon dioxide.

(NH4)2CO3 and NH4HCO3 are heated to produce NH3 and CO2 gases.

NH4CI is the same, but the generated NH3 and CI2 will regenerate NH4CI in a cold environment

The latter produces ammonia gas. The first two pyrolysis to produce ammonia are ammonium carbonate ((NH4)2CO3), ammonium bicarbonate (NH4HCO3) and ammonium nitrate (NH4NO3), as well as nitrogen dioxide, water vapor, water vapor and carbon dioxide produced by the decomposition of nitric acid.

(NH4)2CO3 or NH4HCO3

The chemical equation is.

nh4)2co3=nh3+h2o+co2(nh4)2co3+hcl=nh4cl+h2o+co2(nh4)2co3+2naoh=na2co3+nh3+h2o

I'm in my second year of high school. Wrong to come to me.

nh4hco3

NH3 + CO2 + H2O, ammonium bicarbonate.

It is decomposed by heat to produce ammonia, carbon dioxide and water.

Heavy metal nitrates:

Thermal decomposition will produce two kinds of gases and one elemental substance.

From the hg---au part, it is guessed that the decomposition products of the cracked heavy metal nitrate are metals, and the volume ratio of No2 and O2 is 2:1, which can be easily written as a reaction panicle.

For example: hg(

no32=hg

o2+2no2↑.

1. Hydrogen.

The active metal reacts with dilute hydrochloric acid and dilute sulfuric acid to form hydrogen.

2. Oxygen. Hydrogen peroxide reacts with manganese dioxide to produce oxygen.

3. Carbon dioxide.

Marble reacts with dilute hydrochloric acid to produce carbon dioxide and calcium chloride, as well as water.
