Question

1Химическая реакция возможна между веществами формулы которых : A.H2SO4иCO Б.H2SO4 и Au B.H2CO4uBACO Г.H2So4uMgO2оксид углерода (IV)не взаимнодействует с веществом.формула каторрого: А.СА(OH)2. Б.So2. B.H2O. Г.Ba(OH)2

Answer 1

1)A.реакция не идет

Б.реакция не идет

В.H2SO4+BaCO3=BaSO4+CO2+H2O               Возможно так

 

Г.H2SO4+MgO=MgSO4+H2O

2)СO2+Ca(OH)2=CaCO3+H2O

 

 CO2+SO2=?

CO2+H2O=H2CO3

CO2+Ba(OH)2=BaCO3+H2O

 

 

 

 

 

 

 

Answer 2

Chemical Reactions between Substances with Given Formulas

Let's analyze the given substances and their formulas to determine if chemical reactions are possible between them.

1. A. H2SO4 and CO: - Sulfuric acid (H2SO4) is a strong acid, while carbon monoxide (CO) is a colorless, odorless gas. - Chemical reaction: No specific reaction is known to occur between sulfuric acid and carbon monoxide.

2. B. H2SO4 and Au: - Sulfuric acid (H2SO4) is a strong acid, while gold (Au) is a noble metal. - Chemical reaction: No specific reaction is known to occur between sulfuric acid and gold.

3. C. H2CO4 and BACO: - H2CO4 is not a recognized chemical formula. It seems to be a typographical error. - Correction: Assuming you meant H2CO3, which is carbonic acid, and BACO, which is not a recognized formula, we can analyze the possible reaction between carbonic acid and an unknown substance. - Chemical reaction: No specific reaction is known to occur between carbonic acid and the unknown substance BACO.

4. Г. H2SO4 and MgO2: - Sulfuric acid (H2SO4) is a strong acid, while magnesium dioxide (MgO2) is an oxide of magnesium. - Chemical reaction: Sulfuric acid can react with magnesium dioxide to form magnesium sulfate (MgSO4) and water (H2O). - The balanced chemical equation for this reaction is: H2SO4 + MgO2 -> MgSO4 + H2O [[1]].

5. Г. Formula of the substance that does not react with carbon dioxide (CO2): - The given options are: A. СА(OH)2, Б. SO2, B. H2O, Г. Ba(OH)2. - Chemical reaction: Carbon dioxide (CO2) does not react with water (H2O). - Therefore, the correct option is B. H2O.
