have you considered balancing each equation?
Um, could you help me with that pls?
I will do one:
AgNO₃ + MgCl₂ --> AgCl +Mg(NO₃)2
you copied that incorrectly. now, starting from that, you need two nitrates on the left:
2AgNO₃ + MgCl₂ --> AgCl +Mg(NO₃)2
Nitates are balanced, but silver...
2AgNO₃ + MgCl₂ --> 2AgCl +Mg(NO₃)
now, all are balanced, including silver and chloride.
AgNO₃ + MgCl₂ --> AgCl +Mg(NO₃)2
