Question

Which of the following choices represents an oxidation-reduction reaction? Li$_2$CO$_3$(s) $\rightarrow$ Li$_2$O(s) + CO$_2$(g) Fe$_2$O$_3$(s) + 6HCl(aq) + 9 H$_2$O(l) $\rightarrow$ 2FeCl$_3$(H$_2$O)$_6$(aq) CaCO$_3$(s) + 2HCl(aq) $\rightarrow$ CaCl$_2$(aq) + H$_2$O(l) + CO$_2$(g) 3 HNO$_2$(aq) $\rightarrow$ HNO$_3$(aq) + 2NO(g) + H$_2$O(l)

          Which of the following choices represents an oxidation-reduction reaction?
Li$_2$CO$_3$(s) $\rightarrow$ Li$_2$O(s) + CO$_2$(g)
Fe$_2$O$_3$(s) + 6HCl(aq) + 9 H$_2$O(l) $\rightarrow$ 2FeCl$_3$(H$_2$O)$_6$(aq)
CaCO$_3$(s) + 2HCl(aq) $\rightarrow$ CaCl$_2$(aq) + H$_2$O(l) + CO$_2$(g)
3 HNO$_2$(aq) $\rightarrow$ HNO$_3$(aq) + 2NO(g) + H$_2$O(l)

Which of the following choices represents an oxidation-reduction reaction?
Li2CO3(s) → Li2O(s) + CO2(g)
Fe2O3(s) + 6HCl(aq) + 9 H2O(l) → 2FeCl3(H2O)6(aq)
CaCO3(s) + 2HCl(aq) → CaCl2(aq) + H2O(l) + CO2(g)
3 HNO2(aq) → HNO3(aq) + 2NO(g) + H2O(l)
