Answer:
Desolving process occur when salt is added in water.
Hey there!
V/V % = ( volume of solute ( mL ) / volume solution ) * 100
volume solute = 25 mL acetone
Volume solvent = 75 mL water
So :
v/v = 25
------------ * 100
25 + 75
v/v = ( 25 / 100 ) * 100
v/ v = 25%
hope this helps!
The correct answer is iron
All organic material has decaying Carbon-14 in it. But if plants and animals are still alive, they constantly replace the supply of Carbon in their systems so the amount of Carbon 14 in the system stays constant. Once a plant or animal dies, the Carbon is no longer regenerated and so the Carbon 14 starts to decay.
