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.
Answer:There is a iin dipole attraction between two hydrogen atom
Explanation:
The same atoms have the ion dipole attraction between them the same atoms repel each other
<em>ANSWER:</em>
Objects that have the same charge, both positive or both negative, repel each other, and those with opposite charges attract each other. ... Similar to electric charges, opposite poles attract, and like poles repel. The stronger the magnets and the closer together they are, the stronger the magnetic force between them.
Electrolytes are substances which are capable of producing a solution that has the ability to conduct electricity. These electrolytes are formed from the dissociation of salts into ions. The positive ions are named cations while the negative ions are termed anions.
Hence, the answer to these item is SALT. Salt are substances produced by the reaction of cations and anions.
