Question

a) Balance the following chemical equations.
1) Zn + HCI —>ZnCl2 + H2
ii) N2O5 H2O —> HNO3
1) H2O2—>H2O +O2
iv) Pb +O2 –> PBO​

Answer 1

Answer:

here is your answer

1) Zn + 2HCI —>ZnCl2 + H2

ii) N2O5 H2O —> 2HNO3

1) 2H2O2—>2H2O +O2

iv) 2Pb +O2 –> 2PBO

*please mark me as brainlist*

Answer 2

Answer:

1.Zn +2HCl -----> Zncl2+H2

2.N2O5 + H2O —> 2HNO3

3.2H2O2—>2H2O +O2

4.2Pb +O2 –> 2PBO
