The answer is in the photo.
Which of the following measurements is expressed to three significant figures?
C. 5.60 km
Hope this helps!
Answer:
The pressure is higher than the atmospheric one, therefore the temperature is less.
Explanation:
When it is closed permanently, the pressure of the pot inside it increases, generating that the atoms and particles of the water are closer together, increasing their kinetic energy, if intermolecular friction and therefore the boiling point is lower, because the water reaches a boil or boil at a lower temperature.
Answer:
As the kinetic energy of the gaseous solute increases, its molecules have a greater tendency to escape the attraction of the solvent molecules and return to the gas phase. Therefore, the solubility of a gas decreases as the temperature increases.

Answer:
222.91g of KCl
Explanation:
First, we need to write a balanced equation for the reaction. This is illustrated below
2K + Cl2 —> 2KCl
Molar Mass of KCl = 74.55 g/mol
Mass of KCl from the balanced equation = 2 x 74.55 = 149.1g
Molar Mass of Cl2 = 2 x 35.45 = 70.9g.
From the equation,
70.9g Cl2 produced 149.1g of KCl.
Therefore, 106 g of Cl2 will produce = (106 x 149.1)/70.9 = 222.91g of KCl
