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 emotions affect our perception?
How do emotions affect our perception? Emotional arousal guides attention so that people’s attention tends to be drawn to objects that are arousing. As we shall see, some of the important influences of emotion on perception are mediated by attention, but emotion can also influence pre-attentive perceptual processes. How do emotions affect reality? Emotions drive […]
Will Vinegar float on water?
Will Vinegar float on water? They don’t mix in water and will float. Household vinegar consists almost entirely of water, but with some acetic acid molecules dissolved in it. Is isopropyl alcohol heavier than water? This means that water and isopropyl alcohol must have different densities and that the water is more dense than isopropyl […]
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 are the main causes of habitat destruction?
What are the main causes of habitat destruction? Habitat destruction is the leading cause of biodiversity loss. Activities such as harvesting natural resources, industrial production and urbanization are human contributions to habitat destruction. Pressure from agriculture is the principal human cause. Some others include mining, logging, trawling, and urban sprawl. Why do animals die when […]
Why is my house so full of static electricity?
Why is my house so full of static electricity? Static increases when the air gets cold and humidity drops. To stay warm in your home, you turn up the heat, further adding to a decrease in humidity and increasing static. While static can be annoying and sometimes painful, there are some simple things you can […]
How do you know if a property is intensive or extensive?
How do you know if a property is intensive or extensive? Extensive properties, such as mass and volume, depend on the amount of matter being measured. Intensive properties, such as density and color, do not depend on the amount of the substance present. Physical properties can be measured without changing a substance’s chemical identity. Which […]
