Need Help Balancing Equations.

[Tait]

Set 15 equations, stuck on 4 of them.

2NaOH + H₂SO₄ = Na₂SO₄ + H₂o
NH₃ + O₂ = NO + H₂O
MgO + HNO₃ = Mg(NO₃)₂ +H₂O
CuSO₄ + NaOH = Cu(OH)₂ + Na₂SO₄

If anyone can help please do, i would be grateful.

Why wouldn't you use balancer? http://www.webqc.org/balance.php
Although you need to retype those equations above because they are in a strange encoding.

Click on the links below to see what I mean:
