What is the best way to describe a metallic bond?

What is the best way to describe a metallic bond? A metallic bond is the sharing of many detached electrons between many positive ions, where the electrons act as a “glue” giving the substance a definite structure. It is unlike covalent or ionic bonding. Metals have low ionization energy. Therefore, the valence electrons can be […]

Unlike humans, these mammals have lenses that allow UV light though. Even though they lack the specialized UV-sensitive type of cone, the other three kinds of cones can combine to make up for […]

Why places near the sea have humid climate?

Why places near the sea have humid climate? Coastal cities that are closer to the sea and oceans are humid as a result of their proximity to the water bodies. Air always holds some degree of water vapour in it. So there is a specific amount of vapour that air can hold. Is humidity higher […]

How do I calculate the average percentage increase?

How do I calculate the average percentage increase? To calculate the percentage increase: First: work out the difference (increase) between the two numbers you are comparing. Increase = New Number – Original Number. Then: divide the increase by the original number and multiply the answer by 100. % increase = Increase ÷ Original Number × […]

What is the condition of a starved evaporator coil?

What is the condition of a starved evaporator coil? A starved evaporator coil is a condition in which not enough refrigerant has been supplied through the total coil length. Therefore, expansion of the refrigerant has not occurred through the whole coil length, resulting in poor coil operation and too-low heat exchange. When a refrigeration unit […]

Is Mg OH 2 an acid or base?

Is Mg OH 2 an acid or base? Because Mg(OH)2 is listed in Table 15.6. 1, it is a strong base. The nitrogen in C5H5N would act as a proton acceptor and therefore can be considered a base, but because it does not contain an OH compound, it cannot be considered a strong base; it […]
