Question

Определить объем кислорода, который потребуется для сжигания 10 литров бутана.(C4H10)Ответьте пожалуйста!!!!!!!!

Answer 1

10 л Х л
2 С4Н10. + 13 О2. -> 8СО2. + 10 Н2О
n=2моль n=13 моль
Vm=22,4 л/моль. Vm=22,4 л/моль
V= 44,8 л V= 291 л

10 л С4Н10. - Х л О2
44,8 л С4Н10. - 291 л О2
V(O2)= 10 * 291 / 44,8 = 65 л

Answer 2

Calculation of Oxygen Required to Burn 10 Liters of Butane (C4H10)

To determine the volume of oxygen required to burn 10 liters of butane (C4H10), we need to consider the balanced chemical equation for the combustion of butane:

C4H10 + 13/2 O2 → 4 CO2 + 5 H2O

From the balanced equation, we can see that 1 mole of butane (C4H10) reacts with 13/2 moles of oxygen (O2) to produce 4 moles of carbon dioxide (CO2) and 5 moles of water (H2O).

To calculate the volume of oxygen required, we need to convert the volume of butane (C4H10) to moles using the ideal gas law:

PV = nRT

Where: - P is the pressure (assumed constant) - V is the volume of the gas (butane) - n is the number of moles of the gas (butane) - R is the ideal gas constant - T is the temperature (assumed constant)

Since we are given the volume of butane (10 liters) and the molar mass of butane (C4H10) is approximately 58.12 g/mol, we can calculate the number of moles of butane:

n = V / molar mass

Substituting the values, we get:

n = 10 L / 58.12 g/mol

Now, we can use the stoichiometry of the balanced equation to determine the number of moles of oxygen required. From the balanced equation, we know that 1 mole of butane reacts with 13/2 moles of oxygen. Therefore, the number of moles of oxygen required is:

moles of oxygen = (13/2) * n

Finally, we can convert the moles of oxygen to volume using the ideal gas law:

V = n * RT / P

Where: - V is the volume of the gas (oxygen) - n is the number of moles of the gas (oxygen) - R is the ideal gas constant - T is the temperature (assumed constant) - P is the pressure (assumed constant)

Please note that the values of pressure and temperature are not provided in the question, so we cannot calculate the exact volume of oxygen required without this information. However, the general procedure outlined above should help you calculate the volume of oxygen required once you have the necessary values for pressure and temperature.

Please provide the values of pressure and temperature so that we can calculate the volume of oxygen required more accurately.
