balence eq 3

 Certainly, Mayank! Below are the balanced chemical equations as per the Class 10 CBSE format — with and without state symbols where required. These are written in a clean, exam-ready style for classroom use or student worksheets.

✍️ Q2: Write the balanced equations for the following chemical reactions.

(i) Hydrogen + Chlorine → Hydrogen chloride

H2+Cl2→2HCl\text{H}_2 + \text{Cl}_2 \rightarrow 2\text{HCl}

(ii) Barium chloride + Aluminium sulphate → Barium sulphate + Aluminium chloride

3BaCl2+Al2(SO4)3→3BaSO4+2AlCl33\text{BaCl}_2 + \text{Al}_2(\text{SO}_4)_3 \rightarrow 3\text{BaSO}_4 + 2\text{AlCl}_3

(iii) Sodium + Water → Sodium hydroxide + Hydrogen

2Na+2H2O→2NaOH+H2↑2\text{Na} + 2\text{H}_2\text{O} \rightarrow 2\text{NaOH} + \text{H}_2 ↑

✍️ Q3: Write balanced chemical equations with state symbols.

(i) Barium chloride and sodium sulphate (both aqueous) react to form insoluble barium sulphate and sodium chloride solution

BaCl2(aq)+Na2SO4(aq)→BaSO4(s)↓+2NaCl(aq)\text{BaCl}_2 (aq) + \text{Na}_2\text{SO}_4 (aq) \rightarrow \text{BaSO}_4 (s) ↓ + 2\text{NaCl} (aq)

✅ Type of reaction: Double displacement, precipitation
✅ BaSO₄ forms a white precipitate (insoluble in water)

(ii) Sodium hydroxide solution reacts with hydrochloric acid solution to form sodium chloride solution and water

NaOH(aq)+HCl(aq)→NaCl(aq)+H2O(l)\text{NaOH} (aq) + \text{HCl} (aq) \rightarrow \text{NaCl} (aq) + \text{H}_2\text{O} (l)

✅ Type of reaction: Neutralization reaction

Would you like me to turn these into a worksheet, MCQ quiz, or revision flashcards for students?

🧪 Precipitation Reaction

 Certainly, Mayank! Here's a clear, CBSE-exam–oriented explanation of the Precipitation Reaction for Class 10 Science students, with definitions, examples, and concepts aligned with the NCERT syllabus. 🧪 Precipitation Reaction (Class 10 Science – Chapter 1: Chemical Reactions and Equations) 📘 Definition: A precipitation reaction is a type of chemical reaction in which two aqueous solutions react to form an insoluble solid called a precipitate . ✅ This precipitate appears as a solid that settles at the bottom of the reaction mixture. 🔬 General Form: A B ( a q ) + C D ( a q ) → A D ( s ) ↓ + C B ( a q ) AB (aq) + CD (aq) \rightarrow AD (s) ↓ + CB (aq) AB and CD are aqueous ionic compounds AD is the precipitate (solid) CB remains dissolved in water (aqueous) 🧪 Examples from NCERT / CBSE Class 10: ✅ 1. Barium Chloride + Sodium Sulphate (Activity 1.10) BaCl 2 ( a q ) + Na 2 SO 4 ( a q ) → BaSO 4 ( s ) ↓ + 2 NaCl ( a q ) \text{BaCl}_2 (aq) + \te...
