Definition of liquifaction |
|
Answer» A gas can be converted into a liquid through a process called liquefaction. Liquefaction of a gas can occur only when the intermolecular force of attraction between the gas molecules are increased. I think Process of making of liquid from other states is called as liquification Process of ,or state of having been ,made liquids |

What is region behind ductility and malleability |
|
Answer» Ductility is said to be the property of material to stretch without getting damaged. Metals having ductile property can be Stretched into wires........... Malleability is said to be the property of a material to deform under compression . The metals having malleable property can be rolled into sheets The energy is transferred throughout the rest of the metal by the moving electrons. Metals are described as malleable (can be beaten into sheets) and ductile (can be pulled out into wires). This is because of the ability of the atoms to roll over each other into new positions without breaking the metallic bond. |

Difference between bonding molecular orbital and anti bonding molecular orbital? |
| Answer» \tBonding molecular orbitalAnti Bonding molecular orbital Molecular orbitals formed by the additive effect of the atomic orbitals is called bonding molecular orbitalsMolecular orbitals formed by the subtractive effect of atomic is called anti-bonding molecular orbitalsProbability of finding the electrons is more in the case of bonding molecular orbitalsProbability of finding electrons is less in antibonding molecular orbitals. There is also a node between the anti-bonding molecular orbital between two nuclei where the electron density is zero.These are formed by the combination of + and + and – with – part of the electron wavesThese are formed by the overlap of + with – part.The electron density, in the bonding molecular orbital in the internuclear region, is high. As a result, the nuclei are shielded from each other and hence the repulsion is very less.The electron density in the antibonding molecular orbital in the internuclear region is very low and so the nuclei are directly exposed to each other. Therefore the nuclei are less shielded from each other.The bonding molecular orbitals are represented by σ, π, δ.The corresponding anti-bonding molecular orbitals are represented by σ∗ , π∗, δ∗.\t | |

What is carbocation |
|
Answer» hope it help you? Carbocation is defined as a group of atoms that contains a carbon bearing positive charge containing only six electrons in its valance shell. These ions are formed by heterolytic cleavage in which the leaving group takes along with it the shared pair of electrons. |

Explain the formation of a chemical bond |
|
Answer» Right explanation Correct me if i am wrong in this ans explain the formation of a chemical bond? Answer: Chemical bonds refer to the forces holding atoms together to form molecules and solids.They can be formed by sharing of elctrons or by transfer of electrons. They can also said to be the attraction between electrons of one atom to the nucleus of another atom. |

What is enthalpy??? |
|
Answer» It is the heat content of a system at constant pressure Enthalpy is a kind of energy but the difference is that it is in minimum amount i.e.1 mole....... Enthalpy is a property of a thermodynamic system. The enthalpy of a system is equal to the system\'s total internal energy plus the product of its pressure and volume. For processes at constant pressure, the heat absorbed |

What is coal gasification and water gas shift reaction.... |
|
Answer» Thanks yogita..... The water-gas shift reaction (WGSR) describes the reaction of carbon monoxide and water vapor to form carbon dioxide and hydrogen (the mixture of carbon monoxide and hydrogen is known as water gas): CO + H2O → CO2 + H2Nowadays ‘syngas’ is obtained from sewage, sawdust, scrap wood, newspaper etc. The process of getting syngas from coal is called “\'coal gasification. ”.C(s) + H2O → CO(g) + H2(g) |

What is disproportionation reaction with examples? |
|
Answer» I hope your doubt would be cleared ? Disproportionation is a chemical reaction, typically a redox reaction where a molecule is transformed into 2 or more dissimilar products. In a redox reaction, the species is simultaneously oxidised and reduced to form atleast 2 different products.Disproportionation reaction follow the form:-2A-> A\'+A"where A, A\' and A" are all different chemical species.Example:- Hydrogen peroxide converting into water and oxygen is a disproportionation reaction:2 H²O² ---> H²O + O² |

What is viscocity |
|
Answer» Viscosity is that characteristics ot flowing by virtue of which it opposes the relative motion between adjacent layers of flowing fluid Viscosity refers to the resistance to the flow of liquid arising as a result of the internal friction within the layers as they pass over other layer.Viscosity arises due to the strong intermolecular forces between the molecules that holds them together and resist the passing of layers over other.The layers of molecules of the flowing liquid that are in contact with the surface are stationary.Increase in the distance between the two layers increases the velocity of the upper layer. |

What is syngas ?? |
|
Answer» Ur wlcm Thanks Priya Syngas, or synthesis gas, is a fuel gas mixture consisting primarily of hydrogen, carbon monoxide, and very often some carbon dioxide. ... Syngas is combustible and often used as a fuel of internal combustion engines. It has less than half the energy density of natural gas. Thaks Synthesis gas, or syngas, produced from coal gasification, is a mixture of gases, predominantly carbon monoxide (CO) and hydrogen (H2), along with small amounts of carbon dioxide (CO2) ), steam (H2O), sulfur compounds of hydrogen sulfide (H2S), carbonyl sulfide (COS), ammonia and other trace contaminates. |

What is ionic character? |
|
Answer» Ionic character refers to where the compound lies on a continuum between totally ionic and totally covalent. the term "ionic bonding" is given when the ionic character is greater than the covalent character – that is, a bond in which a large electronegativity difference exists between the two atoms, causing the bonding to be more polar (ionic) than in covalent bonding where electrons are shared more equally |
