Decomp. ~ 2H2O —-> 2H2 + O2
Single Disp. ~ AgNO3 + Cu —> CuNO3 + Ag
Double Disp ~ Pb(NO3)2(aq) + 2KI(aq) -> 2KNO3(aq) + PbI2(s)
Combustion ~ CH4 + O2 —> CO2 + 2H2O
Synthesis ~ 2Mg + O2 —> 2MgO
Answer:
Three formula units, Two Ammonium radical and Sulphate radical
Explanation:
Answer:
3) Br-Br
Explanation:
Polarity occurs between Two atoms of unequal electronegativities.
since Br-Br contain only one atom ( ie.Bromine), they have equal electronegativity. So they can't be polar.
