Question

Balance the following equations and also write the type of reaction.
1. Mg + O2 gives MgO
2. Fe2O3 + Al gives Al2O3 + Fe
3. C2H6 +O2 gives CO2 +H2O
4. H2O2 gives H2 + O2
5. P + Cl2 gives PCl3
6. BaCl2 + Al2(SO4)3 gives AlCl3 + BaSO4
7. Zn + HCl gives ZnCl2 + H2
8. PbO + C gives Pb + CO2
9. Pb(NO3)2 + KI gives PbI2 + KNO3
10. KClO3 gives KCl + O2.

Answer 1

2mg+o2= 2mgo
Fe2o3 +2Al=Al2o3+2Fe
C2h6+7/2o2=2co2+3h2o
2p+3cl2=2pcl3
3 Bacl2+Al2(So4) 3=2alcl3+3baso4
Zn+2HCl=Zncl2+h2
2pbo+c=2pb+co2
Pb(no3)+2ki=pbi2+2kno3
2kclo3=3kcl+3o2
