Predicting Products

[vix]

I have two equations I can't figure out the products to:

1. Cr₂O₃+Pb₃N₄ (under aqueous conditions)=?

1a. Does under aqueous conditions mean I put H₂O in the equation or is that just the state its in?
1b. What are the products and how do I balance the equation?

2. Iron (III) chloride and tin (iv) nitrate (under aqueous conditions)=?

2a. Does under aqueous conditions mean I put H₂O in the equation or is that just the state its in?
2b. What are the products and how do I balance the equation?

Also, for both equations what would be the reaction type? (e.g double replacement, synthesis, decomposition)

Thank you:)

Aqueous solution means the compound dissociate in water. But here it is not the case.
1. Not possible, because both are not solouble in water.
2. FeCl₃ would be Fe 3+ + 3 Cl- and Sn(NO₃)₄ Sn 4+ + 4 NO₃-

But also here no reaction, because everything is oxidised already.
