Zn+ H2O ---> ZnO + H2 Zn+ H2O ---> ZnO + H2
Zn + H20 = ZnO + H2
2Zn + O2 ---> 2ZnO
S + o2 --> so2
Metal + oxygen ----> Metal oxide So... 1) Magnesium + oxygen ----> Magnesium oxide 2) Lithium + oxygen -----> Lithium oxide So now try these if your unsure still : 1) Iron + oxygen ----> 2) Copper + oxygen ------> Hope I helped! :D
2 KNO3 ↔ 2 KNO2 + O2
Water and oxygen will not react.
Hydrogen and oxygen are both diatomic, existing naturally as H2 and O2. Since water has twice as many hydrogen atoms as oxygen atoms, the equation is: 2H2 + O2 = 2H2O. Of course the numbers to the right of the element names should be subscripted.
S + o2 --> so2
C2h2+3o2=2c02+2h2o+2c

2 KNO3 ↔ 2 KNO2 + O2
MgCl2
The chemical equation is:SF4 + 2 H2O = SO2 + 4 HF
Water and oxygen will not react.
If the copper nitrate formed is copper (I) nitrate, the equation balances with one atom of each metal and one formula weight of each nitrate. If the copper nitrate formed is copper (II) nitrate, the balanced equation is: 2 AgNO3 + Cu -> 2 Ag + Cu(NO3)2.
This simple equation is: 2H2 + O2 = 2H2O
