Compared to a 2.0 M aqueous solution of NaCl at 1 atmosphere, a 3.0 M aqueous solution of NaCl at 1 atmosphere has a

1 answer:

4 0

The correct answer is option 4. A 3.0 M aqueous solution of NaCl has a higher boiling point and a lower freezing point than <span>a 2.0 M aqueous solution of NaCl where both are at 1 atmosphere. This is explained by the colligative properties of solutions. For the two properties mentioned, the equation for the calculation of the depression and the elevation is expressed as: </span>ΔT = -Km and <span>ΔT = Km, respectively. As we can see, concentration and the change in the property has a direct relationship.</span>

What is a property of most metals?

Dmitry_Shevchenko [17]

(2) They tend to lose electrons easily when bonding is the correct answer.

All metals have either one, two, or three valence electrons. Therefore, they tend to lose these valence electrons in order to have eight valence electrons like noble gases do.

Hope this helps~
