Negative deviation occurs when the total vapour pressure is less than what it should be according to raoult's law. considering the same a and b components to form a non-ideal solution, it will show negative deviation from raoult's law only when: o a. pia p[ao] times x[a] and p[bi < pibo] x[bi as the total vapour pressure (p[ao] xia] + p[b0] xib]) is less than what it should be with respect to raoult's law. o b. the solute-solvent interaction is stronger than solute-solute and solvent-solvent interaction o c. the enthalpy of mixing is negative because stronger attractions are formed. o d. the volume of mixing is negative becasue stronger attractions have led to a contraction in volume o a and b only o a, b and c only all of the above

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.
