Consider the equilibrium system below. Upper N upper H subscript 4 upper H upper S (s) double-headed arrow upper N upper H subscript 4 upper C l (g). If the system is at dynamic equilibrium, which statement is true? Sublimation of the NH4CI crystals stops. Solidification of the NH4CI vapors stops. The rate of sublimation of the NH4CI crystals is equal to the rate of solidification of the NH4CI vapors. The rate of sublimation of the NH4CI crystals is higher than the rate of solidification of the NH4CI vapors.

What does the process of natural selection involve

Write a hypothesis that answers the lesson question, “while observing a chemical reaction, how can you tell which reactant is limiting? ” hypothesis: if a substance is the limiting reactant, then . . because . .

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.
