Question

-
Give balanced chemical equation for following reactions -
a) 4Na +02→2NaO
b) Fe203 + 2AI=Al2O3+Fe
c)NaOH+Zn-—Na2ZnO+H2​

Answer 1

Balancing the equation

a) 4Na+O²---->2Na²0

b) Fe²O³+2AL------>AL²O³+2Fe

c)2NaOH+2Zn----->2NaZnO+H²

Answer 2

(a)4Na + O2 --- 2Na2O

(b)Fe2O3 + 2Al ---- Al2O3+ 2Fe

(c). (Hot&conc.)

Zn + 2NaOH ---- Na2ZnO2 + H2
