I need help with the conversation of mass with this equation
NiCl2 + 2NaOH = Ni(OH)2 + 2NaCl

When I did the number of atoms, they weren't balanced... So what do I do?

Search by reactants (NaOH, NiCl2)

1 NaOH + NiCl2 → NaCl + Ni(OH)2

2 NaOH + Br2 + NiCl2 → NaCl + NaBr + Ni(OH)3

Search by products (NaCl, Ni(OH)2)

1 NaOH + NiCl2 → NaCl + Ni(OH)2

Search by reactants (NaOH, NiCl2) and by products (NaCl, Ni(OH)2)

1 NaOH + NiCl2 → NaCl + Ni(OH)2
