Tại một nhiệt độ nào đó có cân bằng sau: CO2 (k) + H2 (k) -> CO (k) + H2O (k)
Kc = 9/4
Giả sử lúc đầu ta đưa vào bình phản ứng 1 mol CO2, 1 mol H2, 1 mol CO và 1 mol H2O.
Vậy tại điều kiện cân bằng, số mol CO có là?

Identify one disadvantage to each of the following models of electron configuration: -dot structures -arrow and line diagrams -written electron configurations type in your answer below. (answer) -dot structures do not show the distribution of electrons in orbitals and take up a lot of space. -arrow and line diagrams take up a lot of space and make it difficult to count electrons. -written configurations make it easy to lose count of electrons and do not show the distribution of electrons in orbitals.
