Answer: (the answer is highlighted at the end of the explanation)
Step-by-step explanation:
The question requires us to choose all correct statements regarding gas mixtures.
We can analyze the statements about gas mixtures from the point of view of Dalton's Law of partial pressure, which describes how gases behave when in a mixture.
According to Dalton's Law, the partial pressure of a gas in a mixture corresponds to the pressure of an individual gas in the mixture. Also, this Law states that the sum of the partial pressure of components in a gas mixture results in the total pressure of this mixture.
Still, based on the individual partial pressures given by the Dalton's Law, we can say that each gas in a mixture of non-reacting gases behaves independently of the mixture and each of them can be treated separated, although their pressure contributes to the total pressure of the mixture.
Considering the information above, we can mark the following statements as true:
- "Gas mixtures behave the same way as individual gases do"
- "individual gases behave independently of the mixture"
- "to the pressure of a gas mixture, you should add together all the partial pressures of the individual gases in the mixture"
