Sodium sulfate is slowly added to a solution containing 0.0500 m ca2 (aq) and 0.0360 m ag (aq). what will be the concentration of ca2 (aq) when ag2so4(s) begins to precipitate? solubility-product constants, ksp, can be found here.

answer; i do believe the correct answer is (river); /// good luck

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.

the answer is b because, investigating whether another species of moth also drinks tears might be interesting, but it would not directly explain why this species of moth does.

to explain why this species of moth drinks tears, the scientist could ask: "what nutrients that moths need are in elephant tears? "

the scientist could experiment with moth repellent or oter ways to keep the moths away, but that would not answer his original question.
