Question

(घ) निम्नलिखित समीकरणों को संतुलित कीजिए- Mg + O2 =Mgo
Ag + HNO3 =AgNO3 +HONO2
Mgo + H2O =Mg (OH)2
Al + O2=Al3O3
CaO + H2O=Ca(OH)2​

Answer 1

1) Ag + 2${HNO}_{3}$ = ${AgNO}_{3}$ + ${NO}_{2}$ + ${H}_{2}{O}$

2) MgO + ${H}_{2}{O}$ = ${Mg(OH)}_{2}$

3) 4Al + 3${O}_{2}$ = 2${Al}_{2}{O}_{3}$

4) Ca + 2${H}_{2}{O}$ = ${Ca(OH)}_{2}$ + ${H}_{2}$

Answer 2

Answer:

1) Ag + 2{HNO}_{3}HNO

3

= {AgNO}_{3}AgNO

3

+ {NO}_{2}NO

2

+ {H}_{2}{O}H

2

O

2) MgO + {H}_{2}{O}H

2

O = {Mg(OH)}_{2}Mg(OH)

2

3) 4Al + 3{O}_{2}O

2

= 2{Al}_{2}{O}_{3}Al

2

O

3

4) Ca + 2{H}_{2}{O}H

2

O = {Ca(OH)}_{2}Ca(OH)

2

+ {H}_{2}H
