How do you classify a chemical reaction? Classifying Chemical Reactions Synthesis reactions. Two or more reactants combine to make 1 new product. Decomposition reactions. A single reactant breaks down to form 2 or more products. Single-replacement reactions. A single element replaces a similar element of an adjacent reactant compound. Double-replacement reactions. Combustion reactions. What are […]
What is the function of semiconductor?
What is the function of semiconductor? A semiconductor can help controlled flow of electricity. The basic function of such a device is to switch ON and OFF the flow of electricity as and when required. A semiconductor device can perform the function of a vacuum tube with hundreds of times its volume. What is N […]
How do you know if you have inner ear damage?
How do you know if you have inner ear damage? Nausea or vomiting. Tinnitus or ringing in your ears. Hearing loss. Feeling of fullness in your ear. Is inner ear damage permanent? If treated promptly, many inner ear infections cause no permanent damage. In some cases, however, permanent loss of hearing or damage to the […]
Which has more energy infrared or ultraviolet?
Which has more energy infrared or ultraviolet? Ultraviolet radiation carries more energy and infrared radiation less energy than visible light. Does ultraviolet carry energy? Simply put, ultraviolet radiation (also known as UV radiation or ultraviolet rays) is a form of energy traveling through space. Some of the most frequently recognized types of energy are heat […]
Do anions have higher first ionization energy?
Do anions have higher first ionization energy? When electrons are added to an atom there are more electron-electron replusions causing electrons to spread out more in space. Thus, anions are larger than their parent atoms. The first ionization energy of an atom is the energy required to remove the first valence electron from a neutral […]
Why do toilets flush the opposite way in Australia?
Why do toilets flush the opposite way in Australia? Because of the rotation of the Earth, the Coriolis effect means that hurricanes and other giant storm systems swirl counter-clockwise in the Northern Hemisphere, and clockwise in the Southern Hemisphere. In theory, the draining water in a toilet bowl (or a bathtub, or any vessel) should […]
What is the basic principle of air wedge experiment?
What is the basic principle of air wedge experiment? The phase difference between the two rays is used to get interference fringes. It’s alternative light and dark fringes. The path difference between the rays has to be equal. What is meant by air wedge? Air Wedge. An air wedge is a simple interferometer used to […]
What electromagnetic waves can be used for communication?
What electromagnetic waves can be used for communication? Radio waves are used for communication such as television and radio. Radio waves are transmitted easily through air. They do not cause damage if absorbed by the human body, and they can be reflected to change their direction. These properties make them ideal for communications. Which wave […]
What happens when a big star collapses?
What happens when a big star collapses? The outer layers of the star will be ejected into space in a supernova explosion, leaving behind a collapsed star called a neutron star. Ordinary matter, the kind that we and everything around us is made of, is mostly empty. It is made up of atoms, which are […]
Can you have a coefficient of restitution greater than 1?
Can you have a coefficient of restitution greater than 1? It normally ranges from 0 to 1 where 1 would be a perfectly elastic collision. It can be more than 1 if there is an energy gain during the collision from a chemical reaction, a reduction in rotational energy, or another internal energy decrease that […]
