Do polar molecules have to be asymmetrical? Polar molecules MUST have an asymmetrical structure to be polar, because symmetry cancels out net charge. Asymmetrical molecules are always polar. Symmetrical molecules can be polar and non-polar. Polarity is dependent on the difference in electronegativity of the molecule’s atoms and shape. What is an example of asymmetrical? […]
Do electrons move in their orbitals?
Do electrons move in their orbitals? Because an electron is a quantum object with wave-like properties, it must always be vibrating at some frequency. Furthermore, an electron in a stable atomic state does not move in the sense of waving through space. The orbital electron does move in the sense of vibrating in time. Can […]
What best describes white light after it passes through a prism?
What best describes white light after it passes through a prism? Visible light, also known as white light, consists of a collection of component colors. Upon passage through the prism, the white light is separated into its component colors – red, orange, yellow, green, blue and violet. The separation of visible light into its different […]
How many volts is 2000 watts?
Why is burning of candle is both physical and chemical change?
Why is burning of candle is both physical and chemical change? Wax of the candle is made of carbon and hydrogen which reacts with oxygen on burning and changes into carbon dioxide gas and water which escapes into the air. This is a chemical change. As a result, candle melts and reduces in size. This […]
Does current always flow in a loop?
Does current always flow in a loop? Current doesn’t have to flow in a loop, if something is losing charge (like an hot electron plate in space) the charge leaves and never comes back because the electrons boil off. Current is defined by amperes law you could imagine drawing a surface around the plate and […]
What characteristics are used to identify metamorphic rocks?
What characteristics are used to identify metamorphic rocks? Metamorphic rocks were once igneous or sedimentary rocks, but have been changed (metamorphosed) as a result of intense heat and/or pressure within the Earth’s crust. They are crystalline and often have a “squashed” (foliated or banded) texture. What is the classification of igneous rocks based on quizlet? […]
Are sensation and perception the same thing?
Are sensation and perception the same thing? Sensation occurs when sensory receptors detect sensory stimuli. Perception involves the organization, interpretation, and conscious experience of those sensations. How do you test for unconscious proprioception? Position sense (proprioception), another DCML sensory modality, is tested by holding the most distal joint of a digit by its sides and […]
Does blue light have a higher frequency than green?
Does blue light have a higher frequency than green? Blue light has a shorter wavelength and therefore a higher frequency. Blue light has a shorter wavelength and therefore a higher frequency as compared to green light. Some reptiles can see light of shorter wavelengths than humans can see. Which is the least refracted Colour in […]
Can sound create a magnetic field?
Can sound create a magnetic field? – just created by collisions of atoms in the air and the pressure waves created travels in air and gets to your ear drum and the membrane vibrates and if the frequency is right you hear a sound. … Do magnetic fields vibrate? SUMMARY The vibration of a perfectly […]
