FeC13=1 atom of Fe, 3 atoms of CI
I think it is C. i took a quiz on that.
I forget how to do this but I hope it’s right lol
The earth has enough gravity to do that
If we dissolve salt in water they will reduce the intermolecular forces between water molecule and this will decrease the surface tension.
Surface tension is due to cohesive forces (the forces between molecules of same substance) hence as cohesive forces decreases the surface tension also decreases
