1,1-dichlorocyclopropane

trans-1,2-dichlorocyclopropane

cis-1,2-dichlorocyclopropane

cis-1-bromo-2,3-dichlorocyclopropan e (all cis)

1-bromo-1-chlorocyclopropane

trans-1-bromo-2-chlorocyclopropane< br />
cis-1-bromo-2-chlorocyclopropane

Which of these are superimposable?

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.
