The concentration of a and b will decrease while c will increase provided all other physical quantities are kept constant in the reaction
Answer:
B
Explanation:
since isotopeA has bigger mass number
Answer:
Mole fraction O₂= 0.43
Explanation:
Mole fraction is the moles of gas/ total moles.
Let's determine the moles of each:
Moles O₂ → 15.1 g / 16 g/mol = 0.94
Moles N₂ → 8.19 g / 14 g/mol = 0.013
Moles H₂ → 2.46 / 2 g/mol = 1.23
Total moles = 2.183
Mole fraction O₂= 0.94 / 2.183 → 0.43
If you move a substance from one container to another and its volume changes substances is gas.
The answer is permeability
