Answer:
8.55x10^5 in scientific notation
Answer:
The morality of the solution is calculated as 0.859 m. We are required to determine the freezing point depression constant of pure water. The freezing point depression of the solution is given as
* (morality of solution)
and
are the freezing points of the pure solvent (water, 0°C) and
= freezing point depression constant of water. Therefore,
*(0.859 m)
=====> (0°C) – (3.00°C) = 
=====> -3.00°C =
Ignore the negative sign (since
is positive) and get
= (3.00°C) / (0.859 m) = 3.492°C/m
The freezing point depression constant of the solvent is 3.5°C kg/mole
3.5 K.kg/mole (temperature differences are the same in Celsius and Kelvin scales).
Use the distance formula. X 2 = 2 and X 1 = -2
Y 2 = 6 and Y 1 = -2
The answer should be 8.94
Hello!

-4x - 10x
When subtracting terms with the same variable degree (x), we can simply subtract the coefficients from each other:
-4 - 10 = -14
We can add on the x variable once we have done this:
-14x. Therefore, B is the correct answer.
