I will do one:
AgNO₃ + MgCl₂ --> AgCl +Mg(NO₃)<sub>2</sub>
you copied that incorrectly. now, starting from that, you need two nitrates on the left:
2AgNO₃ + MgCl₂ --> AgCl +Mg(NO₃)<sub>2</sub>
Nitates are balanced, but silver...
<b>2AgNO₃ + MgCl₂ --> 2AgCl +Mg(NO₃)</b>
now, all are balanced, including silver and chloride.
AgNO₃ + MgCl₂ --> AgCl +Mg(NO₃)<sub>2</sub>
