Can animals see UV? What they found suggests that most mammals can, in fact, see UV light—including dogs, cats, ferrets, and reindeer. 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? 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? 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 × […]

How do you increase the volume of a solution? The simplest way to change the concentration would be to change the amount of solute or solvent in the solution. Increasing the solute would increase the concentration. Increasing the solvent would decrease the concentration. What is the volume of a solution? Molarity can be used to […]

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 […]

Why must an accurate percent yield be below 100%? Percent yield is the percent ratio of actual yield to the theoretical yield. Usually, percent yield is lower than 100% because the actual yield is often less than the theoretical value. Reasons for this can include incomplete or competing reactions and loss of sample during recovery. […]

Does high ionization energy mean high electronegativity? Ionization Energy Elements with high ionization energies have high electronegativities due to the strong pull exerted on electrons by the nucleus. Does P or CL have a higher ionization energy? The second ionization energy is always larger than the first ionization energy, because it requires even more energy […]

What happened to the alpha particles when they hit the gold foil? Alpha particles only have 2 protons, so the positive charge is not strong enough to attract the electrons in the gold atom. It might have definitely interacted, with the electrons “pulling” them toward themselves, which result in a tiny force which pushed the […]

Do vitamins give energy? Vitamin B-12, or cobalamin, is a nutrient you need for good health. It’s one of eight B vitamins that help the body convert the food you eat into glucose, which gives you energy. Vitamin B-12 has a number of additional functions. What are the main source of fresh water? precipitation What […]
