I don't KNOW. Lolololol

For molecules and polyatomic IONS the coordination number of an atom is determined by simply counting the other atoms to which it is bonded (by either single or multiple bonds).[1] For example, [Cr(NH3)2Cl2Br2]− has CR3+ as its CENTRAL CATION, which has a coordination number of 6 and is described as hexacoordinate. The common coordination numbers are 4, 6 and 8.Explanation:Hope it will help you ☺️.Please mark me as BRAINLIEST ☺️.

In physics, CIRCULAR motion is a movement of an object along the circumference of a circle or rotation along a circular path. It can be uniform, with constant ANGULAR RATE of rotation and constant SPEED, or non-uniform with a changing rate of rotation.

Explanation:Thus, 1 molecule of methane has a total of 10 electrons. Thus 0.1 MOLE of CH₄ CONTAINS "10 x 0.1 x Avogadro NUMBER" of electrons. Therefore 1.6 grams of methane contains 6.022 x 10²³ electrons.

accumulator is a secondary cell because electrical energy is not generated within the cell itself but it is previously stored in it from the external source. ... The energy is stored in the form of chemical energy. So this cell is a storage cell or accumulator or storage BATTERY.The lead acid storage battery is formed by dipping lead peroxide plate and sponge lead plate in dilute sulfuric acid. A load is CONNECTED externally between these plates. In diluted sulfuric acid the molecules of the acid SPLIT into positive hydrogen ions (H+) and negative sulfate ions

redox REACTION MEANS OXIDATION and reduction take place in ONE EQUATION

Atomic nitrogen and atomic oxygen don't exist under "normal" CONDITIONS because each FORMS molecules N2 andO2. N2 is less reactive than O2 in most gaseous reactions because there is a strong triple bond between the ATOMS, all the valence electrons are in bonding orbitals, and more ENERGY is needed to excite them.

Change in color of CRYSTALS from green to brown. This is because of the ferrous sulfate crystals on HEATING will loose water molecules and TURN to white which immediately turns brown due to formation of FERRIC oxideWater droplet will be OBSERVED on the wall of the boiling tube. Removal of water molecules from the crystals will get condensed on the walls of boiling tube.

yes! it's answer is TRUE because that SOLID make that the water and then INCREASE the temperature so it makes a GAS.

ionism is the economic policy of restraining trade between states through methods such as tariffs on imported goods, restrictive quotas and a VARIETY of other government REGULATIONS designed to allow (ACCORDING to proponents) “fair COMPETITION” between IMPORTS and goods and services produced domestically.

Explanation:A decomposition reaction is a type of chemical reaction in which a compound is broken down into SIMPLER components. It is the opposite of chemical synthesis, in which elements or relatively simple compounds combine to produce one that is more complex. Since a decomposition reaction involves the breaking of chemical bonds, it requires the addition of energy; this may come from heat, an electrical current or other sources. Sometimes, a catalyst will speed up the reaction or allow it to take place at a lower temperature. These reactions are used industrially in the production of some elements — especially reactive metals — and in the laboratory for the analysis of samples. A decomposition reaction is a breakdown of chemical bonds. A decomposition reaction is a breakdown of chemical bonds. Decomposition by Heat Heat is commonly used to bring about a decomposition reaction. When a compound heats up, its atoms move about more vigorously, and this movement can break chemical bonds. For example, if calcium carbonate (CaCO3) is strongly heated, it will decompose into calcium oxide (CaO) and carbon dioxide (CO2). The temperature required to decompose a compound depends on the strength of the bonds that hold it together. In this example, calcium carbonate loses an atom of carbon and two atoms of oxygen as CO2, but the calcium holds on to one oxygen atom because the calcium-oxygen bond is very strong and cannot be broken by heating to any easily achievable temperature. Heat is often used to bring about a decomposition reaction. Heat is often used to bring about a decomposition reaction. The more reactive elements tend to form stronger bonds and are, therefore, more difficult to SEPARATE from their compounds. In contrast to the above example, the oxides of less reactive metals, such as silver and mercury, can be decomposed by relatively moderate heating, releasing oxygen and LEAVING the pure metal. Highly reactive metals, such as sodium and potassium, cannot be separated from their compounds by heating alone. Electrolysis In the liquid state, elements can be separated from a compound by the application of a direct electric current in a process known as electrolysis. The current flows through electrodes, which are placed in the liquid. Negatively charged electrons flow into one electrode, known as the cathode, and out of the other, which is known as the anode. The cathode therefore has a negative charge, and the anode, a positive charge. Ions in the liquid move toward the oppositely charged electrode, allowing the current to flow. An example is the decomposition of water into hydrogen and oxygen by electrolysis. Pure water is a very poor conductor, but the introduction of even a very small amount of an ionic compound, such as sodium sulfate, greatly improves its conductivity and allows electrolysis to take place. At the cathode, water (H2O) is split into hydrogen gas (H2) and hydroxide (OH-) ions, which are attracted to the positively charged anode. At the anode, water is split into oxygen gas and hydrogen (H+) ions, which are attracted to the cathode. Other Factors In some compounds, the energy needed for decomposition is small and can be supplied by a minor shock, such as a physical impact. One such compound is lead azide (Pb(N3)2), which decomposes explosively into lead and nitrogen gas if subjected to a fairly small impact. Sodium azide is a similar, but slightly less sensitive, compound that is used to inflate car airbags in a collision. Light can cause the decomposition of some compounds. For example, silver chloride is converted to silver and chlorine gas on exposure to light. This phenomenon was crucial to the development of photography. Catalysts In many cases, a decomposition reaction can be prompted or speeded up by the use of a catalyst. These substances do not take part in the reaction, and are therefore unchanged by it, but they encourage the reaction to take place. A good example is the decomposition of DILUTE solutions of hydrogen peroxide (H2O2) into water and oxygen. This reaction can be promoted by the addition of powdered manganese dioxide, which acts as a catalyst to produce oxygen gas.
