How do you know which bond is more ionic? If the electronegativity difference between the two elements is greater than or equal to 1.7, the bond is more ionic than covalent. There are several formulas for calculating percent ionic character. They give a fair correlation with ionic character as determined by dipole moments. How do […]
What happened to the food coloring dropped in the bottle containing water after one day?
What happened to the food coloring dropped in the bottle containing water after one day? Answer Expert Verified * the food coloring drops on the water, as it drops, it spreads throughout the bottle smoothly. * when it spreads, it’s starting to loss its color. * when dropped on the water, it spreads in any […]
At what time we will be equal to half of the total energy?
Is pitch directly proportional to loudness?
Is pitch directly proportional to loudness? It is directly proportional to the square of the amplitude of vibration. If the amplitude of the sound wave becomes double, then the loudness of the sound will be quadrupled. It is expressed in decibel (dB). Sounds above 80 dB becomes noise to human ears….Loudness of Sound. Normal Breathing […]
Can I see Jupiters moons with binoculars?
Can I see Jupiters moons with binoculars? The four major moons of Jupiter are called Io, Europa, Ganymede and Callisto. This is a telescopic view, but you can glimpse one, two or more moons through your binoculars, too. Can you see Mars moons with binoculars? A few can actually be viewed with binoculars if you […]
What happens to the carbon 12 atoms while the carbon-14 atoms are decaying?
What happens to the carbon 12 atoms while the carbon-14 atoms are decaying? Carbon-12 and carbon-13 are both stable, while carbon-14 is unstable and has a half-life of 5,730 ± 40 years. Carbon-14 decays into nitrogen-14 through beta decay. A gram of carbon containing 1 atom of carbon-14 per 1012 atoms will emit ~0.2 beta […]
Does nuclear radiation ever go away?
Does nuclear radiation ever go away? Nuclear waste, for example, remains radioactive for eons. But after about 3000-20000 years (depending on the type of reactor) nuclear waste is only as radioactive as naturally occurring uranium ore. The rule for nuclear explosions is 7 times 7 times 7. After 7 hours, 90% of the radioactivity is […]
Is the core of earth solid or liquid?
Is the core of earth solid or liquid? The core of the Earth is made up mainly of iron, in an outer liquid layer and an inner solid layer. The outer core is where the circulating conducting liquid generates the geodynamo, responsible for our magnetic field. What is an interesting fact about the inner core? […]
Do holograms exist in real life?
Do holograms exist in real life? Holograms exist. “Holograms” as depicted in Star Trek and other Sci Fi movies do not and cannot exist. A traditional optical hologram is a diffraction grating formed by recording an interference pattern between two or more coherent laser beams in film. What is Holosexual? Holosexual is a playful term […]
Does GPS need phone signal?
Does GPS need phone signal? Do you need a mobile phone signal for GPS to work on smartphones? No. There is some confusion in that, if a mobile signal is available to them, Smartphones may use something called Assisted GPS to gain the approximate location from the phone signal. What is the most accurate GPS? […]
