Is pcl5 an ionic compound? Phosphorus pentachloride Is PCl5 both ionic and covalent? PCl5 is a covalent in gaseous and liquid states but ionic in solid state. Is MoCl6 ionic compound? The result is an electron-pair sharing bond which looks a lot like a covalent bond between Mo & Cl with one electron from Mo […]

How do I identify an alluvial fan? Check the mouths of tributaries in larger valleys while in the field. Check topographic maps, and look for fan shaped elevation lines at the mouths of tributaries. Check soils maps for soils designated as “local alluvium.” What is the human impact of alluvial fan? Willful and continuous interference […]

How far back in time can we see? But 13.8 billion light years is far too small to be the right answer. In actuality, we can see for 46 billion light years in all directions, for a total diameter of 92 billion light years. What is beyond the universe? These 93 some-odd billion light-years contain […]

When a parallel plate capacitor is being charged by a DC battery Why does a galvanometer? Answer Expert Verified During charging and discharging of the capacitor, there is a flow of charge from the battery towards the plates of the capacitor, which produces a conduction current in the circuit. Hence, the galvanometer present in the […]

Is Internet a secondary source? The Internet is currently a component of the secondary data sources, one of the possible secondary data sources. The use of the Internet as a secondary source of data means both advantages and disadvantages; the qualities of the Internet should not be overvalued, although they exist. Which is an example […]

How can we use the solar energy? Solar energy is used today in a number of ways: As heat for making hot water, heating buildings and cooking. To generate electricity with solar cells or heat engines. To take the salt away from sea water. To use sun rays for drying clothes and towels. It is […]

Is Ursa Minor the North Star? Ursa Minor, though, is almost entirely represented by the Little Dipper. The most famous star in the Little Dipper is Polaris, which is currently known as the North Star or Pole Star, as it appears to be aligned with Earth’s axis, or Celestial Pole. How do you identify Ursa […]

Does snow make sounds? Snow can make both ‘squeaky’ and ‘crunchy’ sounds. Snow is a mixture of ice crystals, liquid water and air, and the sound it makes when you walk on it depends on the proportions of this mixture. When you walk on snow, your boots apply pressure that can break its ice crystals. […]

Does the Fermi level depend on temperature? The experiment shows that the Fermi level decreases with increasing temperature and has almost the same temperature dependence as the energy gap. It is pinned at about 0.63 of energy gap below the conduction band. How is Fermi level calculated? You can use our Fermi level calculator to […]

Are 2s and 2p degenerate? The 2s and 2p orbitals have the same energy for hydrogen. They are said to be degenerate energy levels, all the same. When the electron is held in the 1s orbital, it is said to be in its ground state, its lowest energy state. When the electron is a higher […]
