When metal a is placed in a solution of metal ions b2+, a reaction occurs between a and b2+, and metal ions a2+ appear in the solution. when metal b is placed in acid solution, gas bubbles form on its surface. when metal a is placed in a solution of metal ions c2+, no reaction occurs. which of the following reactions would not occur spontaneously?
a. c(s) + 2h+(aq) β h2(g) + c2+(aq)
b. c(s) + a2+(aq) β a(s) + c2+(aq)
c. b(s) + c2+(aq) β c(s) + b2+(aq)
d. a(s) + 2h+(aq) β h2(g) + a2+(aq)
e. b(s) + 2h+(aq) β h2(g) + b2+(aq)

Rocks, as they are compressed, begin forming mountains above the earth's surface when two continental plates converge. the continental crust increases in depth as the mountains grow above. the himalayan mountains formed at a convergent plate boundary in this manner. the rocks are smashed together causing them to due to the intense heat and pressure from the colliding plates and eventually forming rock. a) melt; igneous b) layer; sedimentary c) recrystallize; metamorphic d) melt into the earth's interior; metamorphic
