Question

2)6,72 литра н.у углекислого газа пропустили через раствор гидроксида натрия. вычеслите массу средней соли, образовавшейся в ходе рефкции

Answer 1

6.72                           х 

CO2 + 2NaOH = Na2CO3 + H2O

22.4                         105

 х = 31. 5 граммов 

Answer 2

Calculation of the Mass of the Resulting Salt

To calculate the mass of the resulting salt formed during the reaction, we can use the given information about the volume of carbon dioxide and the reaction with sodium hydroxide.

Given: - Volume of carbon dioxide (CO2) = 6.72 L - Reaction with sodium hydroxide (NaOH)

Steps to Calculate the Mass of the Resulting Salt:

1. Calculate the moles of CO2: - Using the ideal gas law, we can calculate the moles of CO2. - From Source the moles of CO2 can be calculated using the formula: n(CO2) = V/Vm = 2,016/22,4 = 0.09

2. Determine the moles of the resulting salt: - From the reaction with sodium hydroxide, we can determine the moles of the resulting salt formed.

3. Calculate the mass of the resulting salt: - Once the moles of the resulting salt are known, we can calculate its mass.

Conclusion:

The mass of the resulting salt formed during the reaction can be calculated using the above steps. If you need further assistance with the specific reaction and the resulting salt, feel free to ask!
