Question

Природный газ объемом 240л н.у использовали для получения ацетилена. Объемная доля метана в газе составляет 85%. Определите объем обраовавшегося ацетилена, приведенный к н.у , если его выход составил 60%. Ответ: 61,2 л НУЖНО РЕШЕНИЕ!!(((

Answer 1

2СН4 = С2Н2 + 3Н2

240*0,85*0,6/2=61,2 л ацетилена

Calculation of the Volume of Acetylene Produced

To determine the volume of acetylene produced, we need to consider the volume of natural gas used and the methane content in the gas.

Given: - Volume of natural gas used: 240 L (at normal conditions) - Methane content in the gas: 85% - Acetylene yield: 60%

To find the volume of acetylene produced, we can use the following steps:

Step 1: Calculate the volume of methane in the natural gas. - Methane content in the gas: 85% - Volume of natural gas used: 240 L - Volume of methane = Methane content * Volume of natural gas - Volume of methane = 0.85 * 240 L = 204 L

Step 2: Calculate the volume of acetylene produced. - Acetylene yield: 60% - Volume of acetylene = Acetylene yield * Volume of methane - Volume of acetylene = 0.60 * 204 L = 122.4 L

Step 3: Convert the volume of acetylene to normal conditions (n.u.). To convert the volume of acetylene to normal conditions, we need to consider the temperature and pressure at which the acetylene was produced. Since this information is not provided, we will assume that the conversion is done at the same temperature and pressure as the natural gas.

Therefore, the volume of acetylene produced, converted to normal conditions (n.u.), is approximately 122.4 L.

Please note that this calculation assumes ideal gas behavior and does not take into account any other factors that may affect the reaction or the volume of acetylene produced.
