Explain about valence shell electron pair repulsion theory?? no need to copy from Google on the spot answer will be reported... |
|
Answer» ding to the VSEPR theory, every atom in a molecule will ADOPT geometry such that the repulsion between the valence ELECTRONS in the atoms is minimal. ✔✔And the electron pairs prefer to OCCUPY maximum distance from each other. ✔✔The VSEPR theory varies for molecules with the presence of pairs and multiple bonds around the central atom. ✔✔On the central atom of a molecule, the repulsion between two lone pairs of electrons is the greatest. ✔✔The repulsion between a bond pair and another bond pair is the weakest, and that between a lone pair and a bond pair is between these two.

What are cooling equipments in laboratory |
|
Answer» rnd ..*_*Lab Cooling EquipmentHome > Lab Cooling EquipmentLab Cooling Equipments are the most significant tools required in almost all kind of lab across the world. Lab Cooling Equipment INCLUDES Blood Bank Refrigerator, Blood Bank Scale, Close loop water chillers, COLD CHAMBER, Cryo Bath, Deep Freeze, Hermetic Sealed Compressor, Laboratory Refrigerator and the likes. All kinds of reagent required in chemistry analysis requires refrigeration, and out of which some must be kept at a definite temperature to remain stable. In this regards, laboratory REFRIGERATORS are much needed for this job, as a NORMAL household refrigerator might not have the firm temperatures requirement by the products used in the laboratory. Most of the lab products needing refrigeration are quite sensitive to certain low or high temperatures.

What do you mean by black hole |
|
Answer» hole is a region of space time exhibiting such strong gravitational effects that nothing—not even particles and electromagnetic radiation such as light—can escape from inside it.The theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole.The boundary of the region from which no escape is possible is called the event HORIZON. Although the event horizon has an enormous effect on the fate and circumstances of an object crossing it, no locally detectable features appear to be observed. In many ways a black hole acts like an ideal black body, as it reflects no light.Moreover, quantum field theory in curved spacetime predicts that event HORIZONS emit Hawking radiation, with the same spectrum as a black body of a temperature inversely proportional to its mass. This temperature is on the order of billionths of a kelvin for black holes of stellar mass, making it essentially impossible to observe.Objects WHOSE gravitational fields are too strong for light to escape were first considered in the 18th century by John Michell and Pierre-Simon Laplace.The first modern solution of general relativity that would characterize a black hole was found by Karl Schwarzschild in 1916, although its interpretation as a region of space from which nothing can escape was first published by David Finkelstein in 1958. Black holes were long considered a mathematical curiosity; it was during the 1960s that theoretical work showed they were a generic PREDICTION of general relativity. The discovery of neutron stars in the late 1960s sparked INTEREST in gravitationally collapsed compact objects as a possible astrophysical reality. |

The word 'electron'has its origin in greek word called 'amber' |
|
Answer» d electricity derives from New Latin and ultimately Greek. It first appears in English in Francis Bacon's writings. Depending on context, the word MAY refer to "electric charge", "electric POWER" or "electric energy".The experiment with a pumped-out glass bulb, in which an electric circuit is completed by electrons emitted from a hot wire, is credited to the US inventor Thomas Alva EDISON (1847-1931), who patented it in 1883. The phenomenon is known as the "Edison effect" and many electronic devices use it nowadays.pls.pls mark as brainliest i rquest a lotExperiments with beams of negative particles were performed in Britain by Joseph John ("J.J.") Thomson, and led to his conclusion in 1897 that they consisted of lightweight particles with a negative electric charge, nowadays known as electrons. Thomson was awarded the 1906 Nobel Prize.The word "elektron" in Greek means amber, the yellow fossilized resin of evergreen trees, a "natural plastic material" already known to the ANCIENT Greeks. It was known that when amber was rubbed with dry cloth--producing what now one would call static electricity--it could ATTRACT light objects, such as bits of paper. |

How do forest maintain water table? |
|
Answer» maintain the ground WATER table by maintaining the rain waterflow and by absorbing water via root system of plants. Porous forest soils and debris stores the water allowing the SLOW release of water into surface waters and groundwaterThe best way to control dryland salinity in Victoria is to prevent groundwater recharge by using rain where it falls instead of allowing it to MOVE down through the soil beyond plant roots into the ground water system.The role of rainforests in the water cycle is to add water to the atmosphere through the PROCESS of transpiration (in which plants release water from their leaves during photosynthesis). ... When forests are cut down, less MOISTURE goes into the atmosphere and rainfall declines, sometimes leading to drought.I HOPE IT WILL HELP YOU DEAR THANKU |
