During the centuries following the collapse of the western Roman Empire, marble (calcium carbonate, CaCO3) was taken from the mon-
uments of Rome and heated to form quicklime (calcium oxide, Cao),
which was used to make plaster. Carbon dioxide, CO2, was also pro-
duced in this decomposition reaction. Write the balanced equation for
this reaction.

Which statements are true concerning mineral formation? check all that apply. the slower the cooling, the larger the crystals. the faster the cooling, the smaller the crystals. crystals formed from magma are smaller than crystals formed from lava. minerals can only form in solutions when the solution is heated deep underground. when a solution cools, elements and compounds leave the solution and crystallize as minerals. minerals formed from hot water solutions can form narrow channels in the surrounding rock.
