Answer:

a. Impurities

c. Recrystallizing solvent

Explanation:

In this type of reaction the products are never considered totally pure, that is why as a final product it must always be taken into account that it is proportional, it will be a recrystallization solvent and other impurities with which the products were mixed.

a gas that exerts a pressure of 215 torr in a container with a volume of 51.0 mL will exert a pressure of ? torr when transferre
zhannawk [14.2K]
To calculate the new pressure, we can use Boyle’s law to relate these two scenarios (Boyle’s law is used because the temperature is assumed to remain constant). Boyle’s law is:

P1V1 = P2V2,

Where “P” is pressure and “V” is volume. The pressure and volume of the first scenario is 215 torr and 51 mL, respectively, and the second scenario has a volume of 18.5 L (18,500 mL) and the unknown pressure - let’s call that “x”. Plugging these into the equation:

(215 torr)(51 mL) =(“x” torr)(18,500 mL)
x = 0.593 torr

The final pressure exerted by the gas would be 0.593 torr.

Hope this helps!

What happens to the ancient calendar during the winter and summer solstices
iris [78.8K]

During the winter solstices, we experience the longest day and the shortest night while during the summer solstices the sun is at its highest point in the sky.

<h3>What is the Solsticest?</h3>

The Solstices is the season that occurs at the moment the earth's tilt toward or from the sun is at a maximum. There are two seasons of Solstices which include the following:

  • The winter solstices: This occurs when the sun is directly over the Tropic of Capricorn causing us to have the shortest day and longest night of the year.

  • The summer solstices: The sun is at its highest elevations.
