What is the product of these single replacement reactions

Post by blue »

1. Ni(II) + Cu2O --> ???

2. Na + HNO3 --> H2 + Na(NO3) (Is this correct ?)
2Na + 2 HNO3 --> H2 + 2 Na(NO3) balanced ?

1. Ni(II) + Cu2O = NiO + 2Cu(I)

2. Na would not react this way with HNO3, As far as I remember it forms N2O:
8 Na + 10 HNO3 = 8 NaNO3 + N2O + 5 H2O
