2KClO3 -> (t°, MnO2) 2KCl + 3O2

3O2 -> (UV) 2O3

O3 + 2Ag -> Ag2O + O2

4Na + O2 -> (t°) 2Na2O

Na2O + H2O -> 2NaOH

2NaOH + Cl2 -> NaCl + NaClO + H2O

2NaCl -> (đpnc) 2Na + Cl2

H2S + 4Cl2 + 4H2O -> H2SO4 + 8HCl

\(2KClO_3\rightarrow\left(t^o,MnO_2\right)2KCl+3O_2\)

\(3O_2\rightarrow\left(tia.UV\right)2O_3\)

\(2Ag+O_3\rightarrow Ag_2O+O_2\)

\(4Na+O_2\rightarrow2Na_2O\)

\(Na_2O+H_2O\rightarrow2NaOH\)

\(NaOH+HCl\rightarrow NaCl+H_2O\)

\(2NaCl\rightarrow\left(đp\right)2Na+Cl_2\)

\(Cl_2+2H_2O+SO_2\rightarrow H_2SO_4+2HCl\)

Bài 1:

Theo đề ta có : A₁=G₁; T₁=3A₁; X₁ = 2T₁

=>\(\left\{{}\begin{matrix}X_1=6A_1\\T_1=3A_1\\G_1=A_1\end{matrix}\right.\)=>\(\left\{{}\begin{matrix}A=4A_1\\G=7A_1\end{matrix}\right.\)

Lại có: 2A + 3G= 5800

=> 29A₁ = 5800 => A₁=200

=> G = 1400

Số thứ n là: 1+2+3+...+n

Số thứ 2022 là:

2022x2023: 2 = 1011x2023=
