What is the correct balanced equation for the following:
potassium iodide + lead(II) sulfide --> lead(ii) iodide + potassium sulfide
(A) 2KI + PbS -> Pbl2, +K2S
(B) KI + PbS-> Pbl + KS
(C) KI + Pb25 -> Pb2l + KS
(D) 2KI + Pb25 -> Pb2l2 + K2s

Melting and boiling are endothermic processes. this means that these processes absorb energy from their surroundings in order to occur. use this information and the data you collected in the phase change gizmo to describe what happens to the temperature of water when you boil it, then explain why this result occurs.

Using data from seismic waves, geologists have learned that earth’s interior is made up of several
