Chemical Reactions

Question

Predict the products and states for the follow set of reactants. Be sure to balance the final equation. For each

reaction, you must provide a written explanation of how you know what type of reaction and what the products

are. If no reaction, write NR – no need to write products and states for a reaction that does not occur.

1. _____ Al(OH)3 (aq) + _____ H2 SO4(aq) 

2. ____Zn(s) + ____Al(NO3)3 (aq) 

3. _____ C2 H2 + _____ O2 

4. _____ Al2 (CO3)3 

5. ____ Zn (s) + ____Sn(NO3)4(aq) 

6. ____MgSO3(aq) + ____Pb(NO3)2(aq) 

7. ____NaBr (aq) + ____KNO3 (aq) 

Answer 1

1) Al(OH)₃ (aq) + H₂SO₄(aq) ==> = NO REACTION (all reactants and products are soluble and fully ionized)

2) Zn(s) + Al(NO3)3 ==> NO REACTION (Zn less active than Al and can't replace it)

3) 2C₂H₂(g) + 5O₂(g) ==> 4CO₂ (g)+ 2H₂O(g)

You try the rest with the following hints:

4) Decomposition reaction

5) Single replacement reaction where Zn is more reactive than Sn

(6) Double replacement reaction where PbSO3 precipitates

(7) Products would be NaNO3 + KBr but all are soluble and all are fully dissociated (no reaction?)
