3. Hexane is nonpolar (the carbons amd hydrogens are equally distributed throughout this organic compound, so the partial charges balance eachother) and water is polar.
Hormones travel through the body by using blood streams, such as veins. The hormones then get to the target cell by moving through the liquids surrounding the cells. They then change how the cell works, thus changing the body.
Answer:change in number of atoms
Explanation:AP3X
I believe the correct answer from the choices listed above is the first option. When Br2 and NaF are mixed, no reaction would occur since Br cannot replace F in NaF. By looking at the positions of the halogens in the periodic table, bromine is located way below fluorine. Reactivity of bromine would be low as compared to fluorine so it will not have enough energy to replace fluorine in the compound as it will not have sufficient energy to bind. The position of the halogens are F, Cl, Br, I and At where fluorine is the most reactive element.
Answer:
I belive it is C. but im not 100% sure.
