WebWhen anhydrous blue cobalt (II) chloride crystals are added to water they turn pink and the reaction is reversible. When the cobalt (II) chloride crystals are heated in a test tube, the pink crystals turn back to the blue colour again as the water of crystallisation is lost. The form of cobalt (II) chloride in the crystals that are pink is ...

WebEach atom is made of subatomic particles called protons, neutrons, and electrons. The protons and neutrons are located at the centre of the atom, which is called the nucleus. The electrons move very fast around the nucleus in orbital paths called shells. The mass of the electron is negligible, hence the mass of an atom is contained within the ... WebElectrolysis: General Principles. When an electric current is passed through a molten ionic compound the compound decomposes or breaks down. The process also occurs for aqueous solutions of ionic compounds. Covalent compounds cannot conduct electricity hence they do not undergo electrolysis. Ionic compounds in the solid state cannot …
WebAnswer. The correct answer is 4. The relatively high melting point, solubility in water and electrical conductivity when molten suggest that X is a giant ionic structure. The low melting point of Y suggests that little energy is needed to break the lattice which corresponds to a simple molecular structure.
bambus bastelnWebThe Periodic Table. There are over 100 chemical elements which have been isolated and identified. Each element has one proton more than the element preceding it. This is done so that elements end up in columns with other elements which have similar properties. Elements are arranged on the periodic table in order of increasing atomic number. bambus bauhausWebFreezing is when a liquid changes into a solid. This is the reverse of melting and occurs at exactly the same temperature as melting, hence the melting point and freezing point of a pure substance are the same. Water, for example, freezes and melts at 0 ºC. Requires a significant decrease in temperature (or loss of thermal energy) and occurs ... bambus baumWebApr 8, 2015 · Asif Anderson.
