| Rendered form | Sample ChemTeX answer string |
|---|---|
| C_{17}H_{18}F_3NO | |
| Na{^+} | |
| - | {NO_3}{^-} |
| Al(NO_3)_3 | |
| 3+ | [Fe(H_2O)_6]{^{3+}} |
| {^{39}_{17}}Cl | |
| {^{238}_{92}}U | |
|
{Cr_2O_7}{^{2-}}(aq)+14H{^+}(aq)+6e{^-}\rightarrow 2Cr{^{3+}}(aq)+7H_2O(l) |
|
|
AB_2 + heat \rightarrow A{^{2+}} + 2B{^-} |
| S(s) + O_2(g) \rightarrow SO_2(g) | |
 |
SO_2(g) + \frac{1}{2}O_2(g) \rightleftharpoons SO_3(g) |
| {^{28}_{14}}Si + \gamma \rightarrow {^{24}_{12}Mg + \alpha | |
| O{^*}(g) +H_2O(g) \rightarrow 2OH(g) | |
| {^{60}}Co{^\ast} \rightarrow {^{60}}Co + \gamma | |
| n \rightarrow p + \beta{^-} + \bar{\nu}_{e} | |
