The Correct answer is Option 4. 

Key Points⇒ The sequence decreases by  −4 each time.

⇒ The formula for the  n-th term of an AP is: a_n = a₁ + (n-1) .d 

⇒ Here, a₁ = 14 , d = -4 , n = 14 

⇒  a₁₄ =14 + (14−1)(−4) = 14 − 52 = −38.

Hence Option 4 is correct.

The Correct answer is Option 3.

Key Points

• The constituents of a soda acid fire extinguisher are:
• Sodium Bicarbonate (Baking Soda):
• Chemical Formula: NaHCO₃.
• Acts as a source of carbon dioxide when it reacts with acid.
• Sulfuric Acid:
• Chemical Formula: H₂SO₄.
• Provides the acidic medium to react with sodium bicarbonate. Hence, option 3 is correct.
• Reaction:
• When the fire extinguisher is activated, sulfuric acid reacts with sodium bicarbonate to produce carbon dioxide gas (CO₂), which helps in extinguishing the fire by displacing oxygen.
• The reaction is:
• 2NaHCO₃+H₂SO₄→Na₂SO₄+H₂O+2CO₂ (gas)
• Working Principle:
• Carbon dioxide is heavier than air and forms a blanket over the fire, cutting off the oxygen supply needed for combustion.
• The water formed in the reaction also helps in cooling the fire.
• This type of fire extinguisher is effective against Class B fires (flammable liquids) and Class C fires (electrical fires).
