Uzgodnij równania reakcjii

..N_{2} + ..O_{2} = ..NO_{2}

..Na + ..O_{2} = ..Na_{2}O

..Fe + .. O_{2} = ..Fe_{3}O_{4}

..Cu + .. Cl_{2} = ..CuCl

..H_{2} +..Cl_{2} = ..HCl

..P + ..O_{2} = ..P_{2}O_{5}

..SnCl_{4} + ..Mg = ..MgCl_{2} + Sn

..KI + ..Br_{2} = ..KBr + ..I_{2}

..PbO_{2} + ..H_{2} = ..Pb + ..H_{2}O

..Fe_{2}O_{3} + ..C = ..Fe + CO_{2}

..Mg + ..HCl = ..MgCl_{2} + ..H_{2}

..Fe + ..H_{2}O = ..Fe_{3}O_{4} + ..H_{2}

Proszę was o dopisanie poprawnych liczb oraz o wyjaśnienie mi tego. Jutro mam z tego kartkówkę, a ja kompletnie nie wiem o czym ta kobieta do mnie mówi.
