The diagrams shown on p. 273 represent various physical
Chapter 6, Problem 146P(choose chapter or problem)
The diagrams shown on p. 273 represent various physical and chemical processes. (a) \(2 A(g) \rightarrow A_{2}(g)\). (b) \(M X(s) \rightarrow M^{+}(a q)+X^{-}(a q)\). (c) \(A B(g)+C(g) \rightarrow A C(g)+B(g)\). (d) \(B(l) \rightarrow B(g)\). Predict whether the situations shown are endothermic or exothermic. Explain why in some cases no clear conclusions can be made.

The diagrams shown on p. 273 represent various physical and chemical processes. (a) \(2 A(g) \rightarrow A_{2}(g)\). (b) \(M X(s) \rightarrow M^{+}(a q)+X^{-}(a q)\). (c) \(A B(g)+C(g) \rightarrow A C(g)+B(g)\). (d) \(B(l) \rightarrow B(g)\). Predict whether the situations shown are endothermic or exothermic. Explain why in some cases no clear conclusions can be made.
ANSWER:
Step 1 of 4
The chemical reactions which release the energy are called exothermic reactions and the reactions which absorb the energy are called endothermic reactions.
