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 so
lution. 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) → H2(g) + C2+(aq)
B. C(s) + A2+(aq) → A(s) + C2+(aq)
C. B(s) + C2+(aq) → C(s) + B2+(aq)
D. A(s) + 2H+(aq) → H2(g) + A2+(aq)
E. B(s) + 2H+(aq) → H2(g) + B2+(aq)
earth surface is uneven because land heats faster than water causes air to warm.,expand and rise over land while it cools and sinks over the cooler waters surface..
