Question

Balance the equation:
step-by-step explanation​

Answer 1

Answer:

hey mate here ure answer

c.Zn+2KOH --K2ZnO2+H2O

d.Fe2O3+CO--2Fe+CO2

Answer 2

hope this helps u

Zn+koh-----------------------> k2ZnO2+H2

put 2 before  kOH reactant side

equation balanced zn + 2koh -------> k2zno2+h2

Fe2O3+CO --------> Fe+CO2

put 2 before Fe in product side and 3 before CO in reactant side  and 3 before CO2 in product side

equation balanced  Fe2O3+ 3CO --------------> 2Fe + 3CO2

PbO + NH3-------------> Pb + H2O + N2

put 3 before PbO and  2 before NH3  in reactant side and 3 before Pb and 3 before H2O  in product side

equation balanced  3PbO + 2NH3------------> 3Pb+  3H20+ N2
