Question

balance these chemical equations
Mg+O2=MgO
N2+O2=NO
CH4+O2=CO2+H2O
NO2+H2O=NO+HNO3
pls tell the answer fast
whoever answers the fastest i will mark as brainiest

Answer 1

NH4Cl+NaNO2‡NaCl+N2 +H2O

Hg2O+O2‡HgO

Mg(HCO3)2 + HCl ‡ MgCl2 + H2O + CO2

ZnS+O2‡ZnO+SO2

Al2(SO4)3 + NaHCO3 ‡ Al(OH)3 + Na2SO4 + CO2

As+O2‡As2O3

BaBr2 + Na3PO4 ‡ Ba3(PO4)2 + NaBr

Al2O3 + HF‡AlF3 + H2O

Answer 2

Answer:

2Mg+O2--->2MgO

N2+O2---->2NO

CH4+2O2--->CO2+2H2O

3NO2+H2O----->2HNO3+NO

Hope this answer helps you out.
