In this video, we solve an important Stoichiometry + Limiting Reagent question based on the reaction of calcium with excess HCl at STP conditions.

📌 Question:
14.0 g of calcium reacts with excess HCl at 1 atm and 273 K.
Which of the following statements is incorrect?

Reaction used:
Ca + 2HCl → CaCl₂ + H₂↑

Step-by-step we calculate:
• Limiting reagent (Calcium)
• Moles of Ca = 14 / 40 = 0.35 mol
• Moles of H₂ evolved = 0.35 mol
• Volume of H₂ at STP = 7.84 L
• Mass of CaCl₂ formed = 38.85 g

We verify all options and find:
❌ Statement (c) is incorrect
✅ Correct answer: Option C

This type of question is very important for:
• NEET Chemistry
• JEE Main
• Stoichiometry
• Limiting Reagent concept
