Question

the value of x, y and z in the following balanced equation respectively (x) pb(no3)2 = (y) pbo+(z) no2 + o2
a)2,4,2
b)2,4,4
c)2,2,4
d)4,2,2
​

Answer 1

Explanation:

value of x is 2

y is 2

and

z is 4

so correct op is (c)

Answer 2

The value of x, y and z in the following balanced equation respectively (x) pb(no3)2 = (y) pbo+(z) no2 + o2

c)2,2,4

Lead nitrate, Pb(NO₃)₂ upon decomposition gives Pb(II) oxide as residue along with nitrogen dioxide (NO₂) and oxygen (O₂) gases.

The reaction is shown below.

2Pb(NO₃)₂  → 2PbO + 4NO₂ +O₂

The reaction given above is:

Pb(NO3)2 = (y) PbO+(z) NO2 + O2

Comparing these two reactions, we get

x as 2, y as 2 and z as 4.

So, option (C) is correct. (2,2,4)
