CO2+H2O=? уравнение реакции Какие продукты образуются в результате взаимодействия CO2 + H2O = ? Надо записать молекулярное уравнение реакции, а также решить задачу. Вот условие: какая масса угольной кислоты образуется при пропускании 24 л углекислого газа через 150 г воды?
Molecular equation of the reaction: CO2 + H2O = H2CO3
To find the mass of carbonic acid formed, we first need to calculate the moles of CO2 and H2O involved in the reaction.
Calculate the moles of CO2: 24 L of CO2 at STP (standard temperature and pressure) is equal to 1 mole. So, 24 L of CO2 is equal to 1 mole.
Calculate the moles of H2O: Using the molar mass of water (H2O): Molar mass of H2O = 18 g/mol 150 g of H2O is equal to: 150 g / 18 g/mol = 8.33 mol
Now, since the reaction ratio between CO2 and H2O is 1:1, the moles of CO2 and H2O are equal.
Calculate the molar mass of H2CO3 (carbonic acid): Molar mass of H2CO3 = 62 g/mol
Calculate the mass of carbonic acid formed: Number of moles of H2CO3 = 8.33 mol Mass of carbonic acid = number of moles × molar mass Mass of carbonic acid = 8.33 mol × 62 g/mol = 516.46 g
Therefore, the mass of carbonic acid formed when 24 L of carbon dioxide is passed through 150 g of water is 516.46 g.
