Answer
B,C,D,E
Explanation:
Hydrogen bonds in water forms a tetrahedral ( four sided structure) and not a six sided structure.
The hydrogen bonds are needed to be broken first when heat is applied to change from one state to another.It makes room for more heat to be applied than the required amount which signifies a higher latent heat of melting or vaporization and also a higher heat capacity .
I am very very sorry for sharing 4t so please can u send me the same question again
3 cubic centimeters, Volume= density/ mass
Yes, because they are in the same group also because they are similar with the <span>chemical properties</span>
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.
