SINGLE DISPLACEMENT REACTION

Answer:

Crystallization or CRYSTALLISATION is the process by which a solid forms, where the atoms or molecules are highly ORGANIZED into a structure KNOWN as a crystal. Some of the WAYS by which crystals form are precipitating from a SOLUTION, freezing, or more rarely deposition directly from a gas.

Answer:

B. PURE substance contains only ONE kind of PARTICLE

USING CONSERVATION of mass

Explain s,p,d,f HYBRIDIZATION?

PARSING spdf ORBITAL Hybridization and Simple Bonding. The current spdf-QM electron orbital model is a forced one based on the precepts of a spherical starting point that requires that macro-physical laws no longer APPLY. For atoms to actually bond to one another, atomic orbitals have to be “hybridized”.

ANSWER:

मिश्रण द्रवों, ठोस और गैसों के आपस में मिलाने की क्रिया तथा इस प्रकार उत्पन्न पदार्थों को कहते हैं। या अलग-अलग पदार्थों का आपस में मिलना परन्तु उनके मूल गुणों में कोई परिवर्तन ना होना ?

मिश्रण के प्रकार

मिश्रण को मुख्य रूप से दो भागों में बांटा गया है मिश्रण जिन पदार्थों याद इन कणों से मिलकर बने होते हैंंं उन्हें मिश्रण के अवयवी कण कहते हे

1 समांगी मिश्रण - ऐसे मिश्रण जिनके अवयवी कणों को अलग-अलग नहीं देखा जा सकता है जैसे नमक के जलीय विलयन को नमक और जल में अलग अलग नहीं देखा जा सकता यह एक समांगी मिश्रण का उदाहरण है

2 विषमांगी मिश्रण ऐसे मिश्रण जिनके अवयवी कणों को अलग अलग देखा जा सकता है जैसे पानी के ऊपर तेल डालने पर तथा हिलाने पर तेल ऊपर रह जाता है और पानी नीचे बैठ जाता है पानी और तेल को अलग-अलग कर सकते हैं अतः एक विषमांगी मिश्रण है

जिस तंत्र में केवल एक प्रावस्था होती है, उसे समांगी तंत्र कहते है ओर जिस तंत्र में एक से अधिक प्रावस्थयाऐ होती हैं, उसे विषमांगी तंत्र कहते हैं।

Answer:

A MOLECULE is an electrically neutral group of two or more atoms HELD together by CHEMICAL bonds. Molecules are DISTINGUISHED from ions by their lack of electrical charge

For many solids dissolved in liquid water, the solubility increases with TEMPERATURE. The increase in kinetic energy that COMES with higher temperatures allows the solvent molecules to more effectively break APART the solute molecules that are held together by INTERMOLECULAR attractions.

Answer:

Two different steps are used in this CASE to reach

the same final state of the air. In the FIRST step

the air is heated at a constant volume equal to its

initial valve until the final pressure of 5 bar is

reached. The air temperature at the END of this

step is:

 For this step the volume is constant, and

 During the second step the air is cooled at the

constant pressure of 5 bar to its final state.

CASTE-based trade among the Nakarattars of Tamil Nadu This is not to say that the Nakarattar banking system resembled an economist’s model of Western-style banking systems … the Nakarattars loaned and deposited money with one another in caste-DEFINED social relationships based on business territory, residential location, descent, marriage, and common cult membership. Unlike in modern Western banking systems, it was the reputation, decisions, and reserve deposits shared among exchange spheres defined according to these principles, and not a government-controlled central bank, that … assured public confidence in individual Nakarattars as representatives of the caste as a whole. In other WORDS, the Nakarattar banking system was a caste-based banking system. Individual Nakarattars organised their lives around participation in and MANAGEMENT of various communal institutions adapted to the task of accumulating and distributing reserves of capital. Source: Rudner
