Consider the molecules hcl, hbr, hf, and hi. which would you expect to have the highest boiling point and why
a) hbr because it has the highest mass and the most electrons
b) hcl, because it experiences hydrogen bonding
c) hf, because it has the strongest intermolecular force
d) hi, because it experiences ion dipole forces

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.
