I think the correct answer from the choices listed above is option C.
Calcium carbonate = CaCO3
sulfur dioxide = SO2
oxygen = O2
calcium sulfate = CaSO4
Carbon dioxide = CO2
The correct skeleton equation for the reaction would be CaCO3(s)+SO2(g)+O2(g) --> CaSO4(s)+ CO2(g).
The answer is b. the water molecules are more closely packed together in ice than in water <span />
