The answer is D, all of them have very different masses
Answer:
true because of the elements
The correct response I believe is D. The reaction rate increases because the probability of collisions increases as there are more Zn atoms to react.
1Al2(SO4)3 + 3ZnCl2 → 2AlCl3 + 3ZnSO4
The coefficients represents moles. There is 1 mole of Aluminum Sulfate, 3 moles of Zinc(II) Chloride, 2 moles of Aluminum Chloride, and 3 moles of Zinc(II) Sulfate.
Now add all the coefficients/moles.
9 is the sum of all the coefficients.
