🗺️ अष्टविनायक यात्रा:
1️⃣ मोरगाव (Mayureshwar)
2️⃣ सिद्धटेक (Siddhivinayak)
3️⃣ पाळी (Ballaleshwar)
4️⃣ महाड (Varadvinayak)
5️⃣ थेऊर (Chintamani)
6️⃣ लेण्याद्री (Girijatmaj)
7️⃣ ओझर (Vighnahar)
8️⃣ रांजणगाव (Mahaganapati)
👉 आणि पुन्हा परत मोरगाव येथे यात्रेचा समारोप होतो.
1️⃣ अष्टविनायकांची संख्या – ८
2️⃣ सर्व मंदिरे – पुणे, रायगड, अहमदनगर जिल्ह्यांत
3️⃣ अष्टविनायक यात्रा सुरू व समाप्त – मोरगाव (Mayureshwar)
4️⃣ महागणपती – रांजणगाव, पुणे जिल्हा
5️⃣ महागणपतीचे वैशिष्ट्य – शिवाने त्रिपुरासुर वधापूर्वी पूजा केली
6️⃣ एकमेव गुंफेतील गणपती – गिरीजात्मज (लेण्याद्री)

oxidation state calculation
🔹 1️⃣ H₂O → (पाणी)
Hydrogen = +1
Oxygen = x
✅ Oxygen = –2
🔹 2️⃣ H₂O₂ → (Hydrogen Peroxide)
Hydrogen = +1
Oxygen = x
✅ Oxygen = –1
(Peroxide bond असल्यामुळे)
🔹 3️⃣ Na₂O₂ → (Sodium Peroxide)
Sodium = +1
Oxygen = x
✅ Oxygen = –1
(Peroxide compound again)
🔹 4️⃣ KO₂ → (Potassium Superoxide)
Potassium = +1
Oxygen = x
✅ Oxygen = –½
(Superoxide compound मध्ये)
🔹 5️⃣ OF₂ → (Oxygen Difluoride)
Fluorine = –1
Oxygen = x
✅ Oxygen = +2
(इथे Fluorine जास्त विद्युतऋण असल्याने Oxygen positive oxidation state मध्ये आहे)
🔹 1️⃣ H₂O → (पाणी)
Hydrogen = +1
Oxygen = x
2(+1) + x = 0
x = -2 ✅ Oxygen = –2
🔹 2️⃣ H₂O₂ → (Hydrogen Peroxide)
Hydrogen = +1
Oxygen = x
2(+1) + 2x = 0
x = -1 ✅ Oxygen = –1
(Peroxide bond असल्यामुळे)
🔹 3️⃣ Na₂O₂ → (Sodium Peroxide)
Sodium = +1
Oxygen = x
2(+1) + 2x = 0
2 + 2x = 0
x = -1 ✅ Oxygen = –1
(Peroxide compound again)
🔹 4️⃣ KO₂ → (Potassium Superoxide)
Potassium = +1
Oxygen = x
(+1) + 2x = 0
2x = -1
x = -½ ✅ Oxygen = –½
(Superoxide compound मध्ये)
🔹 5️⃣ OF₂ → (Oxygen Difluoride)
Fluorine = –1
Oxygen = x
x + 2(–1) = 0
x – 2 = 0
x = +2 ✅ Oxygen = +2
(इथे Fluorine जास्त विद्युतऋण असल्याने Oxygen positive oxidation state मध्ये आहे)
