Atoms of sulfur = 9.60⋅g32.06⋅g⋅mol−1×6.022×1023⋅mol−1 . Because the units all cancel out, the answer is clearly a number, ≅2×1023 as required.
The level of toxins in the fish's cell is equivalent to the level of toxins in the water. Therefore, in order to reduce the toxins further, we should replace the now contaminated water with clean water. After the level of toxins in the fish's cell stops reducing, we replace the water with clean water once again.
Delta S reaction= Delta S products- Delta S reactants
don't forget to mulitiply by coefficients
also
here is a really slow way to do it
you know the moles of gas increased
so Delta S is positive
so its B or D
then just do the units digit to see which one match up
3 mass number- proton number
