Please i need sum help in balancing these equations:
1)Phos(p)+Bromine(Br)=phostribromide(PBr)
2)Cacl2+NAHCO3+H2O=Nacl=Ca(OH)2+H2Co3

Thank You

  • Chemistry -

    Do you mean phorphorus tribromide?
    2P + 3Br2 --> 2PBr3
    Your teacher may prefer it be written as
    P4 + 6Br2 ==> 4PBr3

    I don't think the #2 reaction will go. Ca(HCO3)2 is soluble and there is no other driving force.
