Answer:
calcium carbonate is transformed into calcium sulfate
Explanation:
Limestone stones are formed by calcium carbonate (Ca Co3), when acid rain falls with a little H2SO2, a chemical reaction of the type
Ca Co3 + H2SO4 → CO2 + H2O + CaSo4
Calcium sulfate is much weaker than alatium carbonate, which is why the stone tends to break under its weigh

What they both have in common is that if you are facing a problem, you have to come up with a good solution so that you would have a conclusion to the problem you had in the first place.
Draw a freebody diagram, it will explain it really well
the boat is floating on top of the water, which means that the net acceleration in the y direction must be zero
the boat is not sinking (dominant downwards acceleration/force)
the boat is not flying (dominant upward acceleration/force)
that measn

now, if you drew the FBD, you only have 2 forces acting on the boat.
the upward bouyancy force on the boat and the downward force due to weight

since the net force is equal to zero

and thus
