4.2 Exercise 2

Indicate what type, or types, of reaction each of the following represents:

(a) $\text{Ca} \left(s\right) + \text{Br}_{2} \left(l\right) \rightarrow \text{CaBr}_{2} \left(s\right)$

(b) $\text{Ca} (\text{OH})_{2} \left(a q\right) + 2 \text{HBr} \left(a q\right) \rightarrow \text{CaBr}_{2} \left(a q\right) + 2 \text{H}_{2} \text{O} \left(l\right)$

(c) $\text{C}_{6} \text{H}_{12} \left(l\right) + 9 \text{O}_{2} \left(g\right) \rightarrow 6 \text{CO}_{2} \left(g\right) + 6 \text{H}_{2} \text{O} \left(g\right)$
