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 difference between membrane potential and resting potential?
What is the difference between membrane potential and resting potential? For a cell’s membrane potential, the reference point is the outside of the cell. Because there is a potential difference across the cell membrane, the membrane is said to be polarized. If the membrane potential becomes more positive than it is at the resting potential, […]
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 […]
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 […]
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 […]
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 […]
Is it bad to look at IR light?
Is it bad to look at IR light? All infrared, visible or ultraviolet electromagnetic radiation can cause injury to the eye in sufficient concentrations, but this is very rare. Infrared lamps and incandescent bulbs are not powerful enough to cause such harm. But it’s best if you don’t stare directly at them for too long. […]
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 […]
What role does carbon dioxide play in photosynthesis?
What role does carbon dioxide play in photosynthesis? The carbon dioxide enters the leaves of the plant through small pores called stomata. The plant uses sunlight as energy to perform this chemical reaction. Photosynthesis separates carbon dioxide and water — known as CO2 and H2O, respectively — into their individual molecules and combines them into […]
Do tents attract lightning?
Do tents attract lightning? Tents alone don’t attract lightning, but that doesn’t mean they’re safe during a thunderstorm. The possibility for a tent to get struck by lightning is increased by the campsite location and adjacent tall objects. What happens if lightning hits a tent? If a lightning bolt hits a tent the energy will […]
