Can someone check to see if I wrote the equations correctly?


A. magnesium metal + sulfuric acid

Mg (s) + H2SO4 (aq) --> MgSO4 (aq) + H2 (g)
Mg (s) + 2H+ (aq) + SO4 (2-) (aq) --> Mg (2+) (aq) + H2 (g)
Mg(s) + 2H+ (aq) --> Mg (2+) (aq) + H2 (g)

B. lead (II) nitrate + hydrochloric acid

Pb(NO3)2 (aq) + 2HCl (aq) --> PbCl2 (s) + 2HNO3 (aq)
Pb (2+) (aq) + 2NO3- (aq) + 2H+ (aq) + 2Cl- (aq) --> PbCl2 (s) + 2H+ (aq) + 2NO3 - (aq)
Pb (2+) (aq) + 2Cl- (aq) --> PbCl2 (s)

Thank you for any help.
