Giúp mình với mình cần gấp

Em tham khảo nha:

\(\begin{array}{l}
a)\\
Ca{C_2} + 2{H_2}O \to Ca{(OH)_2} + {C_2}{H_2}\\
{C_2}{H_2} + {H_2} \xrightarrow{t^0,Pd/PdCO_3} {C_2}{H_4}\\
{C_2}{H_4} + C{l_2} \to {C_2}{H_4}C{l_2}\\
{C_2}{H_2} + 2AgN{O_3} + 2N{H_3} \to {C_2}A{g_2} + 2N{H_4}N{O_3}\\
b)\\
2C{H_4} \xrightarrow{t^0} {C_2}{H_2} + 3{H_2}\\
{C_2}{H_2} + 2{H_2} \xrightarrow{t^0,Ni} {C_2}{H_6}\\
{C_2}{H_6} + C{l_2} \to {C_2}{H_5}Cl + HCl\\
{C_2}{H_2} + 2AgN{O_3} + 2N{H_3} \to {C_2}A{g_2} + 2N{H_4}N{O_3}
\end{array}\)
