Question

balance the following chemical equation:-

KMnO⁴ + HCl ---> KCl + MnCl² + Cl² + H²O

and

Al + HCl ---> AlCl³ + Cl²​

Answer 1

$\bigstar$ Answer $\bigstar$

$\checkmark$ Given Chemical Equation

$\blue{\sf KMnO_{4}+HCl \longrightarrow KCl+MnCl_{2}+Cl_{2}+H_{2}O}$

$\checkmark$ Balanced Chemical Equation:

$\red{\sf 2KMnO_{4}+16HCl \longrightarrow 2KCl+2MnCl_{2}+5Cl_{2}+8H_{2}O}$

⇒ For Verification of Balanced Equation

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

$\implies \sf K=2$

$\sf \implies Mn=2$

$\sf \implies O=8$

$\sf \implies H=16$

$\sf \implies Cl=16$

Hence,

The Chemical Equation is said to be balanced

$\checkmark$ Given Chemical Equation

$\green{\sf Al+HCl \longrightarrow AlCl_{3}+H_{2}}$

[ A small correction in the Given Question. Foe the Chemical Equation to be correct H₂ should be present in place of Cl₂ ]

$\checkmark$ Balanced Chemical Equation:

$\orange{\sf 2Al+6HCl \longrightarrow 2AlCl_{3}+3H_{2}}$

⇒ For Verification of Balanced Equation

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

$\sf \implies Al=2$

$\sf \implies H=6$

$\sf \implies Cl=6$

Hence,

The Chemical Equation is said to be balanced
