General knowledge
Science GK: in a chemical equation, reactants are on the left and products on the right (2H₂ + O₂ → 2H₂O); a catalyst speeds up a reaction without being used up; the law of conservation of mass says the mass of reactants equals the mass of products (Lavoisier).
विज्ञान GK में रासायनिक समीकरण में अभिकारक बाईं ओर और उत्पाद दाईं ओर होते हैं (2H₂ + O₂ → 2H₂O); उत्प्रेरक (catalyst) स्वयं खर्च हुए बिना अभिक्रिया तेज़ करता है; द्रव्यमान संरक्षण का नियम कहता है कि अभिकारकों का द्रव्यमान उत्पादों के द्रव्यमान के बराबर होता है (Lavoisier)।
