Can someone please help me balance these equations? Thank you for your time!!


1. NO + O2 ¨ NO2

2. NH4Cl + Ca(OH)2 ¨ CaCl2 + NH3 + H2O

  • Physical Science Help! -

    2NO + O2 ---?? NO2
    I started this one for you.. What goes in front of the NO2?

    Second equation
    On the left you have
    You have 4 N's
    4 H's 2H's or 6 H's
    1 Cl
    1 Ca
    2 O

    On the right you have
    1 Ca
    2 Cl
    1 N
    3 H and 2 H = 5 H
    1 O

    Start by trying to balance the Cl.
