Question

the value of x, y and z in the following balanced equation respectively (x) pb(no3)2 = (y) pbo+(z) no2 + o2 how to find tge values of x and y

Answer 1

$\bigstar$ Answer $\bigstar$

$\checkmark$ Given:

Chemical Reaction:

Decomposition of Lead (II) nitrate

Chemical Equation:

$\orange{\sf (x)Pb(NO3)_2 \longrightarrow (y)PbO + (z)NO_2 + O_2}$

$\checkmark$ To Find:

The values x, y and z

$\checkmark$ Solution:

According to the Question,

We are asked to find the values x, y and z

Hence,

We must find Balanced Chemical Equation for the above given reaction

Therefore,

$\maltese$ Balanced Chemical Equation:

$\red{\boxed{\sf 2Pb(NO3)_2 \longrightarrow 2PbO + 4NO_2 + O_2}}$

$\star$ Verification of Balanced Equation

Both Left-Hand-Side (Reactants) and Right-Hand-Side (Products) contain

• Pb = 2 atoms
• N = 4 atoms
• O = 12 atoms

Therefore,

$\star$ The Chemical Equation is balanced

Hence,

The values are,

$\blue{\sf \longrightarrow x=2}$

$\green{\sf \longrightarrow y=2}$

$\pink{\sf \longrightarrow z=4}$
