The only true statement about an exterior angle of a triangle from the above is that it forms a linear pair with one of the interior angles of the triangle.
<h3>What is a triangle?</h3>
A triangle can be defined as a one of the plane shapes which has three sides and three angles
So therefore, the only true statement about an exterior angle of a triangle from the above is that it forms a linear pair with one of the interior angles of the triangle.

E - This is a permanent dipole dipole attraction
Answer:Hence, in 8g of Oxygen molecules, there are 3. 011 x 10²³ Oxygen atoms. In this way, how many moles are in 16 grams of oxygen? In other words, 1 mole of oxygen would contain molecules

Answer:
the partial pressure of Xe is 452.4 mmHg
Explanation:
Dalton's law of partial pressures says that in a mixture of non-reacting gases, the total pressure exerted is equal to the sum of the partial pressures of the individual gases.
The partial pressures can be calculated with the molar fraction of the gas, in this case, Xe.
Molar fraction of Xe is calculated as follows:


Then, 0.29 is the molar fraction of Xe in the mixture of gases given.
To know the parcial pressure of Xe, we have to multiply the molar fraction by the total pressure:
Partial Pressure of Xe=1560mmHg*0.29
Partial Pressure of Xe=452.4mmHg
Answer:
1.
Mass solution = 28.65 g
Mass percent = 9.14 %
2.
Mass solute = 1.95 g
Mass solution = 48.75 g
3.
Mass solvent = 24.52 g
Mass percent = 6.41 %
4.
Mass solution = 476.8 g
Mass solvent =450.1 g
Explanation:
Hello,
In this case, we define the mass percent as:

Wherein we use the mass of the solute and the mass of the solvent in order to compute it, thus, for each case we have:
1.
Mass solution: 2.65 g + 26.0 g = 28.65 g
Mass percent: 2.62 g / (2.65 g + 26.0 g) x 100% = 9.14 %
2.
Mass solute: 4.0 % x 46.8 g / (1 - 4.0 %) = 1.95 g
Mass solution: 1.95 g + 46.8 g = 48.75 g
3.
Mass solvent: 26.2 g - 1.68 g = 24.52 g
Mass percent: 1.68 g / (1.68 g + 24.52 g) x 100% = 6.41 %
4.
Mass solution: 26.7 g / 5.6 % = 476.8 g
Mass solvent: 476.8 g - 26.7 g =450.1 g
Best regards.
