एक विधि का वर्णन करें जिससे नाइट्रोजन प्रकृति में स्थाई होता है| |
|
Answer» नाइट्रोजन (Nitrogen), भूयाति या नत्रजन एक रासायनिक तत्व है जिसका प्रतीक N है। इसका परमाणु क्रमांक 7 है। सामान्य ताप और दाब पर यह गैस है तथा पृथ्वी के वायुमण्डल का लगभग 78% नाइट्रोजन ही है। यह सर्वाधिक मात्रा में तत्व के रूप में उपलब्ध पदार्थ भी है। यह एक रंगहीन, गंधहीन, स्वादहीन और प्रायः अक्रिय गैस है। इसकी खोज 1773 में स्कॉटलैण्ड के वैज्ञनिक डेनियल रदरफोर्ड ने की थी। आवर्त सारणी के १५ वें समूह का प्रथम तत्व है। नाइट्रोजन का रसायन अत्यंत मनोरंजक विषय है, क्योंकि समस्त जैव पदार्थों में इस तत्व का आवश्यक स्थान है। इसके दो स्थायी समस्थानिक, द्रव्यमान संख्या 14, 15 ज्ञात हैं तथा तीन अस्थायी समस्थानिक (द्रव्यमान संख्या 13, 16, 17) भी बनाए गए हैं। नाइट्रोजन तत्व की पहचान सर्वप्रथम 1772 ई. में रदरफोर्ड और शेले ने स्वतंत्र रूप से की। शेले ने उसी वर्ष यह स्थापित किया कि वायु में मुख्यत: दो गैसें उपस्थित हैं, जिसमें एक सक्रिय तथा दूसरी निष्क्रिय है। तभी प्रसिद्ध फ्रांसीसी वैज्ञानिक लाव्वाज़्ये ने नाइट्रोजन गैस को ऑक्सीजन (सक्रिय अंश) से अलग कर इसका नाम 'ऐजोट' रखा। 1790 में शाप्टाल (Chaptal) ने इसे नाइट्रोजन नाम दिया।Explanation: |

1. Explore the composition of coal and petroleum. Which type of coal is used in thermal power plants?2. Why is LPG considered a better fuel than coal for cooking purposes? (Hint: Think about smoke.)3. Why is LPG filled in cylinders under pressure?4. What is biogas? Is it a fossil fuel?5. Planting of trees helps in checking global warming. How? |
|
Answer» tion:1. Petroleum is a mixture of hydrocarbons (containing C and H). There are mainly three classifications of COAL: Anthracite, Bituminous and Lignite. Lignite has the lowest grade of coal whereas anthracite is the highest one.Power plants generally use steamcoal which is a grade between anthracite and bituminous.2.LPG is considered as a better fuel than coal as it is more eco-friendlythan coal. BURNING of coal releases many toxic gases which affects our health. But on the other hand LPGdoes not have any such nuisance.3.LPG is liquefied petroleum gas (usually butane or propane) filled in cylinders under pressure so that the gas remains in liquid state. ... When the valve is opened thepressure INSIDE the cylinderdecreases and the liquid changes into gas which we use to cook food.4.FOSSIL fuels are ultimately a hydrocarbon fuel and as hydrocarbon fuel they come in many different forms after purified, or refined. Biogas is also a hydrocarbon fuel, but generally speaking biogas is not a fossil fuelbecause it was not mined and captured from a geological deposit.5.Yes planting trees helps in keeping global warmingunder check as trees reduce the amount of carbon DIOXIDE under control by absorbing it and giving out oxygen. Carbon dioxide is a green house gas and trees can keep its amount under control. |

What is radium's atomic mass,and atomic number and other details. add alot of detail please. if added extra detail you will be marked as Brainliest |
|
Answer» m atomic mass☆Radium is a chemical element with the symbol Ra and atomic number 88. It is the SIXTH element in group 2 of the periodic table, also known as the alkaline earth metals. Pure radium is silvery-white, but it readily reacts with nitrogen (rather than oxygen) on EXPOSURE to air, forming a black surface layer of radium nitride (Ra3N2). All ISOTOPES of radium are highly radioactive, with the most stable isotope being radium-226, which has a half-life of 1600 years and decays into radon gas (specifically the isotope radon-222). When radium decays, ionizing radiation is a PRODUCT, which can excite fluorescent chemicals and cause radioluminescence. ☆Atomic Number ☆The atomic number is the number of protons in the nucleus of an atom. The number of protons define the identity of an element (i.e., an element with 6 protons is a carbon atom, no matter how many neutrons may be present). |
