Answer 1

pls follow me and mark me brainlest pls

Answer 2

Answer:

(m) NO₂ + H₂O ⇢ HNO₂ + HNO₃

➤ 2NO₂ + H₂O ⇢ HNO₂ + HNO₃

(n) Pb₃O₄ + HCl ⇢ PbCl₂ + H₂O + Cl₂

➤ Pb₃O₄ + 8HCl ⇢ 3PbCl₂ + 4H₂O + Cl₂

(o) H₂O + Cl₂ ⇢ HCl + O₂

➤ 2H₂O + 2Cl₂ ⇢ 4HCl + O₂

(p) NaHCO₃ ⇢ Na₂CO₃ + H₂O + CO₂

➤ 2NaHCO₃ ⇢ Na₂CO₃ + H₂O + CO₂

(q) HNO₃ + H₂S ⇢ NO₂ + H₂O + S

➤ 2HNO₃ + H₂S ⇢ 2NO₂ + 2H₂O + S

(r) P + HNO₃ ⇢ NO₂ + H₂O + H₃PO₄

➤ P + 5HNO₃ ⇢ 5NO₂ + H₂O + H₃PO₄

• A balanced chemical equation is a equation in which the total mass of the elements present in the products of a chemical reaction is equal to the total mass of the elements present in the reactants.
