The blood the reaches the cells from the capillaries food and O2 pass to cells, CO2 and wastes
pass to blood. The rest of the choices do not answer the question above.
The answer is H—F. Fluorine is the most electronegative of the four halogens (and, in fact, of all the elements), so it does the best job of gathering the shared electrons to itself. Therefore, the bond with F is the most polar
The answer is 2) 4.7 g/mL because the solid use 17 mL and 80g/17mL is 4,7 g/mL.
Answer:
2NF3------->N2 +3F2
Explanation:
For the equation to be balanced, there must be six fluorine atoms on both left and right hand sides of the chemical reaction equation. Hence the coefficient of chlorine on the right hand side must be three for the equation to be balanced.
