    N2 + 3 H2 → 2 NH3

    2 Ba + O2 → 2 BaO

    You need to include some spaces in your formulas to keep YA from truncating them:

    Pb(NO3)2(aq) + 2 KI(aq) → PbI2(s) + 2 KNO3(aq)

    These are not hard. Attept them yourself before you post. If you dont then most people will not help. I will do the first you can do the rest. If you put your attempt in the addition details, I will check in about 20mins

    1(N2) + 3(H2) ----> 2(NH3) You don't usually put it in brackets it just makes it a little easier for you to understand. Just balance so there are equal amounts on each side.

    Looks like someone did them for you..
