Hi, I believe this should belongs to the chemistry section, but nevertheless here is the solution :
Number of Fe atoms: (2) + (2) =4
Number of O atoms. : (3)
Number of H atoms: (3 X 2)=6
Total atoms: 4+3+6=13 atoms
Displacement = distance and direction from the start-point
to the end-point, regardless of the route followed on the way.
From the throw to the 'plop', the displacement is 5 meters down.
I think the awnser is Dark Matter
<span>because the substance in the potassium permanganate crystals are permeable to water, so that means it will dissolve instantly while poured into water </span>
Hey i dont have an answer but i need the points for finals today. Thank you
