• Mention the information provided by a balanced chemical equation.(Any 2 points)

$\:$

Solution:

• Reactants:

$\tt Pb(NO_3)_2 = \sf Lead \: (II) \: nitrate$

• Products:

$\tt NO_2 = \sf \: Nitrogen \: dioxide$

$\tt O_2 = \sf \: Oxygen$

$\:$

Balanced equation:

$\tt2 Pb(NO_3)_2 → 4 NO_2 + O_2 + 2 PbO$

$\:$

Information provided by a balanced chemical equation:

• This is an oxidation-reduction reaction.
• $\sf \: Pb(NO_3)_2$ is an oxidizing agent, $\sf \: Pb(NO_3)_2$ a reducing agent.
