कॉपर का निष्कर्षण हाइड्रोधातुकर्म द्वारा किया जाता है, परंतु ज़िक का नहीं। व्याख्या कीजिए।

Answer»

Explanation:

WHAT SOMEONE SHOULD DO IF SICK

Stay home in another room, away from other people, and use a separate bathroom if available. Restrict contact with pets and other animals, just like you would around other people. Avoid using public transportation, ride-sharing or taxis.

Wear a cloth face cover when around other people (e.g., sharing a room or vehicle) and before ENTERING a HEALTH care provider’s office. See CDC guidelines.

Call a health care provider for medical advice. Older adults and people of any age with serious underlying medical CONDITIONS should call a health care provider as soon as symptoms start.!

Clean and disinfect all surfaces daily and high-touch surfaces frequently throughout the day in your sick room and designated bathroom. High-touch surfaces include phones, remote controls, counters, tabletops, doorknobs, bathroom fixtures, toilets, keyboards, tablets and bedside tables. Follow CDC guidance.

Wash your hands often with soap and water for at least 20 seconds, especially after being in a public place, or after blowing your nose, coughing or sneezing. If soap and water are not READILY available, use a hand sanitizer with at least 60% alcohol.

Cover your coughs and sneezes. Use a tissue to cover your nose and mouth, and throw used tissues in a lined trash can. If a tissue isn’t available, cough or sneeze into your elbow — not your hands. Wash your hands immediately.

Keep track of symptoms, which may APPEAR two to 14 days after exposure. Drinks a lot of fluids to stay hydrated and rest at home. Follow your health care provider’s instructions.....

Compare the equilibrium constants for the systems shown in the table. Which favors products the most? Which favors products the least? Rank these systems in order from most to least in terms of favoring products rather than reactants.A. D > B > A > C B. C > A > B > D C. B > C > D > A D. A > D > C > B (picture to show help me please)

Answer»

Solution :

⚛ Predicting the Extent of a Reaction :

  • High value of equilibrium constant indicates that PRODUCT(s) concentration is high and its low value indicates that concentration of product(s) in equilibrium mixure is loe.
  • Large value of K (larger than about 10^3), favour the products strongly.
  • For intermediate value of K (approximately in the range of 10^{-3} to 10^3), the concentrations of reactants and products are comparable.
  • Small value of equilibrium constant (smaller than 10^{-3}), favour the reactants strongly.

✏ C FAVORS products the most.

✏ D favors products the least.

_________________________________

➡ Order of K (at 25°C) :

  • C > A > B > D

➡ Order of favoring products :

  • C > A > B > D

निम्न पदों (शब्दों) को समझाइए(i) वैद्युत कण संचलन, (ii) स्कंदन, (iii) अपोहन, (iv) टिन्डल प्रभाव,

Answer»

ANSWER:

1.) वैद्युत कण संचलन

कोलॉइडी कणों पर धनात्मक़ या ऋणात्मक विद्युत आवेश होता है। जिससे ये कण विद्युत क्षेत्र के प्रभाव में विपरीत आवेशित इलेक्ट्रोड की ओर अभिगमन करते हैं। विद्युत क्षेत्र में कोलॉइडी कणों के विपरीत आवेशित इलेक्ट्रोड की ओर अभिगमन (MIGRATION) की घटना को विद्युत कण-संचलन कहते हैं।

2.) स्कंदन

जब कोलॉइडी विलयन में किसी विद्युत्-अपघट्य की अल्प मात्रा मिलायी जाती है तो इनके कणों का आवेश नष्ट हो जाता है जिससे कोलॉइडी कण आपस में मिलकर बड़े हो जाते हैं तथा अवक्षेप के रूप में नीचे बैठ जाते हैं। कोलॉइडी विलयन के इस प्रकार अवक्षेपित हो जाने की क्रिया को स्कंदन (coagulation) कहते हैं l

3.) अपोहन

यदि किसी लवण और स्टार्च के विलयन को सैलोफेन की थैली भरकर उसे आसवित जल में लटका दिया जाए तो लवण के आयन सैलोफेन से होते हुए आसवित जल में प्रवेश कर जाते हैं और स्टार्च थैली के भीतर रह जाता : है। यह प्रक्रिया अपोहन (Dialysis) कहलाती है।

4.) टिन्डल प्रभाव

जब प्रकाश किसी कोलायडी(chemical MIXTURE) माध्यम से होकर गुजरता है तो प्रकाश का प्रकीर्णन होता है तथा प्रकाश का मार्ग दिखाई देने लगता है, प्रकाश की इस घटना को ही टिंडल प्रभाव कहा जाता है।
