~~~~~~~~~~~~~~~~~ HELP ME ~~~~~~~~~~~~~~~~~~~~~~

Answer 1

a) 2Al + 6HCl -> 2AlCl₃ + 3H₂

b) 2KMnO₄ -t^o-> K₂MnO₄ + MnO₂ + O₂

c) Fe₂O₃ + 2Al -> Al₂O₃ + 2Fe

d) CO₂ + 2Mg -> 2MgO + C

e) Al + O₂ -t^o-> Al₂O₃

Answer 2

a, 2Al + 6HCl$\to$ 2AlCl₃ + 3H₂

b, 2KMnO₄ $\to$ K₂MnO₄ + MnO₂ + O₂

c. Fe₂O₃ + 2 Al \(\rightarrow\) Al₂O₃ + 2Fe

d. CO₂ + 2Mg \(\rightarrow\) 2MgO + C

e. 4Al + 3O₂ \(\rightarrow\) 2Al₂O₃

Answer 3

\(a,2Al+6HCl→2AlCl_3+3H_2\)

\(b,2KMnO_4\)-tº->\(K_2MnO_4+MnO_2+O_2↑\)

c,\(Fe_2O_3+2Al→Al_2O_3+2Fe\)

d,\(CO_2+2Mg→C+2Mg\)

e,\(4Al+3O_2→2Al_2O_3\)
