C subscript 17 H subscript 18 F subscript 3 NO

C_{17}H_{18}F_3NO

Na superscript +

Na{^+}
NO subscript 3- {NO_3}{^-}
Al (NO subscript 3) subscript 3 Al(NO_3)_3
[Fe(H subscript 2 O) subscript 6 ]3+ [Fe(H_2O)_6]{^{3+}}

{^{39}_{17}}Cl

{^{238}_{92}}U

Cr subscript 2 0 subscript 7 superscript 2- (aq) + 14H superscript + (aq) + 6 subscript e superscript - reaction arrow 2Cr superscript 3+(aq) + 7H subscript2 O(l)

{Cr_2O_7}{^{2-}}(aq)+14H{^+}(aq)+6e{^-}\rightarrow 2Cr{^{3+}}(aq)+7H_2O(l)

AB subscript 2 plus heat reaction arrow A superscript 2+ plus 2B superscript -

AB_2 + heat \rightarrow A{^{2+}} + 2B{^-}
S(s) + O subscript 2(g) reaction arrow SO subscript 2 (g) S(s) + O_2(g) \rightarrow SO_2(g)
SO subscript 2 (g) + one-half O subscript 2 (g) equilibrium arrow SO subscript 3 (g) SO_2(g) + \frac{1}{2}O_2(g) \rightleftharpoons SO_3(g)
{^{28}_{14}}Si + \gamma \rightarrow {^{24}_{12}Mg + \alpha
O superscript * (g) + H subscript 2 O (g) reaction arrow 2 OH(g) O{^*}(g) +H_2O(g) \rightarrow 2OH(g)
superscript 60 Co superscript * right arrow superscript 60 Co + gamma {^{60}}Co{^\ast} \rightarrow {^{60}}Co + \gamma
n reaction arrow p plus beta superscript minus plus nu with overbar subscript e n \rightarrow p + \beta{^-} + \bar{\nu}_{e}
2{^1_1}H + 2{^1_0}n \rightarrow {^4_2}He
