If you can explain how to do these step by step that would be great
K2CrO4 + Pb(NO3)2 -------> ?
and
(NH4)2CO3 + HNO3-------> ?
Also if you can check to make sure that these are right would also be greatly appreciated
1)NaCl + AgNO3 ------> NaNO3 + AgCl
2)BaCl2+ H2SO4 -----> BaSO4 + HCl2
3)NaOH + HCl --------> NaCl + H2O
4)Na2CO3 + HCl ---->Na2Cl + HCO
5)H2SO4 + NH4OH --> H2OH + SO4NH4
6)FeCl3 + NH4OH -----> FeOH+ NH4Cl3
7)Na2SO3 + HCL ------> Na2Cl + SHO3

K2CrO4 +Pb(NO3)2--->2 KNO3 + PbCrO4
(NH4)2CO3 +2HNO3---> H2CO3 +2NH4NO3
You switch partners, but you do need to consider what the oxidation numbers of each partner are. If they were in a compound where their charge was +2, it still will be.
Balance the equations
1. good
2. HCl is the formula for hydrochloric acid., 2HCl
3.good
4. acid on a carbonate will release CO2 gas.
NaCl is the formula for sodium chloride, always
2NaCl + CO2 +H 2O
5. (NH4)2SO4 + HOH (HOH is H2O)
keep the polyatomic ions together
6. FeCl3 goes to Fe(OH)3,NH4Cl, then balance the equation
7.2NaCl, H2SO3, balance the equation
