A vial containing radioactive selenium-75 has an activity of 2.3 mci/ml. If 2.6 mci are required for a leukemia test, how many m
nika2105 [10]

Answer is: 1130 microliters must be administered.

activity(selenium-75) = 2.3 mCi/mL.

radioactivity(Se-75) = 2.6 mCi; mCi is millicurie.

The curie (symbol: Ci) is a non-SI unit of radioactivity.

V(Se-75) = radioactivity(Se-75) ÷ activity(Se-75).

V(Se-75) = 2.6 mCi ÷ 2.3 mCi/mL.

V(Se-75) = 1.13 mL; volume.

V(Se-75) = 1.13 mL · 1000µL/mL.

V(Se-75) = 1130 µL.

What makes an element inert?
ozzi

"The inert gases are obtained by fractional distillation of air, with the exception of helium which is separated from a few natural gas sources rich in this element, through cryogenic distillation or membrane separation. For specialized applications, purified inert gas shall be produced by specialized generators on-site. They are often used by chemical tankers and product carriers (smaller not a big as well as the tendency of inert gases vesselshtop specialized generators are also available for laboratories."

Kryger [21]

Answer:

atmosphere and hydrosphere

Explanation:

The polar ice caps are part of the cryosphere, which in turn is part of the hydrosphere, which is the sphere that contains all the waters on the planet. The atmosphere has been experiencing changes, with the increase of greenhouse gasses being the most noticeable and most important one. These gasses have contributed to the rise of the global temperatures. As the temperatures have been rising, the ice started to melt, thus it was influenced by the atmosphere, and as it is melting it is getting into the ocean water, thus increasing them. The more water there is in liquid form, and the higher the temperatures are, the higher the evaporation will be, so there will an increase in the amount of water vapor in the atmosphere. This is a nice example of the interaction between these two spheres.
