Balancing equations (check my work)?

Question

Aluminum hydroxide neutralized by sulphuric acid

2Al(OH)3 + 3H2SO4 --> Al2(SO4)3 + 6H2O

KI added to Pb(NO3)2

2KI + Pb(NO3)2 --> 2K(NO3) + PbI2

*Can you help me identify the precipitate in the second equation? Thanks for your help.

Answer 1

Looks good.  Nitrates are generally soluble (and potassium nitrate is), so the precipitate would be lead iodide.  You don't need the parens in the formula for potassium nitrate.
