Sodium chloride commonly known as salt (although sea salt also contains other chemical salts), is an ionic compound with the chemical formula NaCl, representing a 1:1 ratio of sodium and chloride ions. With molar masses of 22.99 and 35.45 g/mol respectively, 100 g of NaCl contains 39.34 g Na and 60.66 g Cl. Sodium chloride is the salt most responsible for the salinity of seawater and of the extracellular fluid of many multicellular organisms. In its edible form of table salt, it is commonly used as a condiment and food preservative. Large quantities of sodium chloride are used in many industrial processes, and it is a major source of sodium and chlorine compounds used as feedstocks for further chemical syntheses. A second major application of sodium chloride is de-icing of roadways in sub-freezing weather.

Python is an interpreted, high-level and general-purpose programming language. Python's design philosophy emphasizes code readability with its notable use of significant whitespace. Python is a general-purpose coding language—which means that, unlike HTML, CSS, and JavaScript, it can be used for other types of programming and software development besides web development. That includes back end development, software development, data science and writing system scripts among other things.

समास ‘संक्षिप्तिकरण’ को समास कहते हैं। दूसरे शब्दों में समास संक्षेप करने की एक प्रक्रिया है। दो या दो से अधिक शब्दों का परस्पर सम्बन्ध बताने वाले शब्दों अथवा कारक चिह्नों का लोप होने पर उन दो अथवा दो से अधिक शब्दों के मेल से बने एक स्वतन्त्र शब्द को समास कहते हैं। उदाहरण ‘दया का सागर’ का सामासिक शब्द बनता है ‘दयासागर’।

भारत में वर्षा ऋतु का आगमन जुलाई के महीने में होता है तथा सितंबर के महीने तक वर्षा होती रहती है । यह ऋतु किसानों के लिए वरदान सिद्ध होती है । वे इस ऋतु में खरीफ की फसल बोते हैं । वर्षा ऋतु वनस्पतियों के लिए भी वरदान होती है । वर्षा काल में पेड-पौधे हरे-भरे हो जाते हैं । वर्षा-जल से उनमें जीवन का संचार होता है । वन-उपवन और बाग-बगीचों में नई रौनक और नई जवानी आ जाती है । ताल-तलैयों व नदियों में वर्षा-जल उमड़ पड़ता है । धरती की प्यास बुझती है तथा भूमि का जलस्तर बढ़ जाता है । मेढक प्रसन्न होकर टर्र-टर्र की ध्वनि उत्पन्न करने लगते हैं । झींगुर एक स्वर में बोलने लगते हैं । वनों में मोरों का मनभावन नृत्य आरंभ हो जाता है । हरी- भरी धरती और बादलों से आच्छादित आसमान का दृश्य देखते ही बनता है । वर्षा ऋतु गर्मी से झुलसते जीव-समुदाय को शांति एवं राहत पहुंचाती है । लोग वर्षा ऋतु का भरपूर आनंद उठाते हैं ।

As she started her bus journey, she saw on one side there was the canal and, beyond it, palm trees, grassland, distant mountains, and the blue sky. On the other side was a deep ditch and then acres and acres of green fields. Then the bus rolled on cutting across a bare landscape. She also saw trees along the way. She also saw a young cow running very fast, right in the middle of the road. Then the bus came to a railroad crossing. Valli saw a train approaching from far and it looked very tiny. From there it traversed a busy, well-laid-out shopping street. She was surprised to see the bright looking shops and the clothes on display. She was delighted by the sights that she saw. On the way back, she saw a cow lying dead on the road. This made her very sad. Her view about the world and what happened in the world changed after the trip.

When we add egg-shell to nitric acid, the Nitric acid reacts with calcium carbonate (which is present in the egg-shell) to form calcium nitrate, carbon dioxide gas, and water. -The carbon dioxide gas released from this reaction turns lime-water milky.
Nitric Acid reacts with egg shell to form calcium nitrate, carbon dioxide and water.
Equ:
CaCO3 [s] + 2HNO3 [aqu] --------> Ca(NO3)2 [aqu] +CO2 [g] + H2O [l]
Egg shell + Nitric Acid --------> Calcium Nitrate + Carbon dioxide + Water.

The formula for lime water is Ca(OH)2 and the chemical name for lime water is calcium hydroxide. When water is added to lime calcium hydroxide Ca(OH)2 is formed according to the following reaction.
CaO + H2O → Ca(OH)2
This reaction is strongly exothermic and takes place vigorously with the formation of clouds of steam.
