A1 l aqueous solution is prepared at 25°c with 10-4 moles of hydrocyanic acid (hcn) and 10-3 moles of disodium carbonate (na2co3) and reaches equilibrium. a) list the 8 unknown chemical species (water is not unknown). b) list (do not solve) all 4 equilibrium expressions that describe this system, including the values for the equilibrium constants.

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.
