Ask for help writing a few chemical equations

Reacts with Cl2,S under ignition or heating conditions.

2Fe + 3Cl2 = (ignition) 2FeCl3, Fe + S = (heating) Fes reacts with Cl2,S under ignition or heating conditions.

Cu+Cl2 = (ignition) CuCl2, 2Cu+S = (heating) Cu2S (cuprous sulfide).

Reacts with concentrated H2SO4.

Cu + 2H2SO4 (concentrated) = (heated) CuSO4 + 2H2O + SO2 (gas).

Reacts with concentrated H2SO4.

C + 2H2SO4 (concentrated) = (heated) 2H2O + CO2 (gas) + 2SO2 (gas).

Reacts with concentrated H2SO4.

H2S + H2SO4 (concentrated) = S + SO2 + 2H2O

I advise you to read more books, these are all equations in textbooks, you can find them.

Basically agree with the upstairs view but.

cu+s=cu2s

H2S+H2SO4 may also generate s depending on the situation mainly in quantity.

Are the first two ignited in the air.

1,6fe+3cl2+2s+15o2=2fe2[clo3]3+fe2[so4]3

2,3cu+cl2+s+5o2=2cuclo3+cuso43，cu+2h2so4=cuso4+so2+2h204,c+2h2so4=co2+2so2+2h2o5,h2s+3h2so4=4so2+4h2o

A 1 2H2 + O2 = Ignition = 2H2O

2 Na2CO3+H2SO4==Na2SO4+H2O+CO23 The problem is carbon monoxide.

4 C2H5OH+3O2=Ignition = 2CO2+3H2O2 1 False Laboratory carbon dioxide is used to react with limestone and hydrochloric acid only 2 also wrong Carbon dioxide is not flammable.

2h2+o2===2h20

A pair of two. Carbon dioxide is not burned in oxygen.

1. Ignition = 2H2O

High temperature = 3CO2 + 2Fe

Ignition = 2CO2 + 3H2O

II.1Incorrect The correct one is CaCO3+2HCl=CaCl2+H2O+CO2

2.Incorrect, the correct one is 2CO+O2=Ignition = 2CO2

1) 2 H2 + 2 O2 = 2H20 (= the above condition is ignited) 2) Na2CO3 + 2HCl = 2NaCl + CO2 + H2O3) CO2 + Fe2O3 ?? Is the title wrong, it should be carbon monoxide through red-hot iron oxide???

3) CO+Fe2O3=3CO2+2FE (conditional high temperature) 4) C2H5OH+3O2=2CO2+3H2O (conditional ignition) The second major question is 1 true and 2 false.

1 +O2 == 2H2O (condition is ignition).

H2SO4 == Na2SO4 + H2O + CO2 (add gas symbol after CO2).

3.I don't think this will react...Is carbon monoxide 3CO + Fe2O3 == 3CO2 + 2FE (conditions are high temperatures).

3O2 == 2CO2 + 3H2O (condition is ignition).

II.1False Calcium carbonate and dilute hydrochloric acid should be used to produce carbon dioxide in the laboratory.

CaCO3 + 2HCl == CaCl2 + H2O + CO2 (gas sign to be added after CO2).

2.False: CO2 is not flammable.

But there's a special reaction, which is that magnesium strips can be burned in carbon dioxide gas to form magnesium carbonate solids.

2cuo high temperature 2cu + CO2

2Fe2O3 High Temperature 4Fe + 3CO2 Fe3O4 High Temperature 3Fe + 2CO2

2Fe2O3 = High temperature = 4Fe + 3CO25I won't.

6.Carbon is fully burned in oxygen: C + O2 = ignition = CO27

Charcoal reduction copper oxide: C+ 2Cuo high temperature 2Cu + CO2 +O2 = ignition = 2Co Common reactions and air pollutants in coal furnaces.

1. Causes of gas poisoning.

Write your own about how to prevent it.

Reaction of copper with concentrated nitric acid.

Cu4HNO3 (concentrated) =

cu（no3）2

2no2↑2h2o

Reaction of copper with dilute nitric acid; 3cu ＋8hno3＝3cu（no3）2＋2no↑＋4h2o

Reaction of copper with concentrated sulfuric acid; Cu 2H2SO4 (concentrated) Cuso SO2 2H2O

The reaction of iron with concentrated nitric acid must be heated, and it is passivated at room temperature, Fe is insufficient, Fe + 6Hno3 (concentrated) = ΔFe (No3) 3 + 3H2O + 3 No2

Fe excess, Fe + 4Hno3 (concentrated) = δFe (No3) 2 + 2H2O + 2 No2

Reaction of iron with dilute nitric acid.

Fe is insufficient, Fe + 4Hno3 = = Fe (No3) 3 + 2H2O + NO

Fe excess, 3Fe + 8Hno3 = = 3Fe (NO3) 2 + 4H2O + 2 NO

The reaction of iron with concentrated sulfuric acid must be heated, and it is passivated at room temperature.

Fe 6H2SO4 (concentrated) ==Fe2 (SO4)3

3SO2 6H2O iron with dilute sulfuric acid) Fe H2SO4 FeSO4 H2

They are all redox reactions, and it is relatively simple to match them with the total number of valence rises and falls equally.
