Will chlorine increase pH? Liquid chlorine does not raise pH. When added to water, liquid chlorine (which has a pH of 13) makes HOCl (hypochlorous acid – the killing form of chlorine) and NaOH (sodium hydroxide), which raises pH. So the net effect on pH is zero (or almost zero). Can you use vinegar to […]

Is H2O a single or double bond? Now, in water, i.e. H2O, oxygen is the central atom and can either form one double or two single bonds. We have two hydrogens which can only form single bonds. Thus, in water, oxygen is singly bonded to two hydrogen atoms. Carbon can form four bonds while oxygen […]

Is Surya Grahan good or bad? A Total Surya Grahan or Total Solar Eclipse occurs when the moon passes between the Sun and the Earth, obscuring Earth’s view of the sun completely. It is a rare phenomenon and over the years, it is believed that this eclipse can have a harmful impact on the human […]

Which area on earth receives the most direct sunlight at what angle? During the summer solstice, the Sun shines most directly on the Tropic of Cancer, 23.5 degrees north of the equator, giving its most direct energy on Earth to the Northern Hemisphere. Which area on Earth receives more light? The equator How azimuth angle […]

When one object exerts a force on a second object the second object exerts the same amount of force of the first? Newton’s Third Law – When one object exerts a force on another object, the second object exerts a force on the first object that is equal in magnitude, but opposite in direction; for […]

How long does it take for an object to fall 1 meter? so the time to drop 1 meter is √(2/9.8) = 0.45 seconds. The way to do it using your reasoning is as follows: After t seconds speed is 9.8 x t. So average speed over that interval is 9.8xt/2 as you say in […]

Does Australia have no ozone layer? The ozone layer is depleted in two ways. Firstly, the ozone layer in the mid-latitude (e.g. over Australia) is thinned, leading to more UV radiation reaching the earth. Secondly, the ozone layer over the Antarctic, and to a lesser extent the Arctic, is dramatically thinned in spring, leading to […]

Which light has the highest energy? violet What Color Is Fastest? Norwegian scientists claim color blue is the fastest color. Why electromagnetic energy is important? Explanation: Electromagnetic Radiation is important in Astronomy because it helps us see the universe. It helps us see on earth to (Visible Light) lol. For example, X-Rays are released by […]

When is best time to salt driveway? The best time to treat the ground is before snowfall begins. Treating areas before snow (and freezing rain/ice) begins can help prevent ice from forming and prevent snow from settling. Because salt has a lower freezing point than water, it reduces the opportunities for moisture to freeze on […]
