For this system, we use Dalton's law of partial pressures where the total pressure of a gas mixture is said to be equal to the sum of the partial pressures of the gases. The partial pressure of each gas would be calculated by the product of the mole fraction and the original pressure of the gas. We do as follows:
Total pressure = x1P1 + x2P2
Total pressure = (2.0 / 7.0 )(3.5) + (1.5/7.0)(2.6)
Total pressure = 1.56 atm

Answer:
HF: hydrogen bond
Explanation:
The hydrogen bond is a type of interaction that is established between a molecule that presents hydrogen with another that presents an atom with a high electronegativity, such as oxygen, fluorine or nitrogen (O, F, N), joining covalently due to their opposite charges.
The hydrogen atom has a positive charge and is known as a donor atom. The oxygen, fluorine or nitrogen atom is the bond acceptor atom.
So:
<u><em>HF: hydrogen bond</em></u>
Answer:
To express y in terms of x is to find an expression that relates the value of x with y. This is to write a model, function, expression or formula that permits to input a value for x and the outcome will be the value of y. .For example if you have y = 2x, y is in terms of x and you can input different values of x to obtain corresponding values (outputs) of y.
