Is a pH of 11 acidic or basic?
What is the relationship between heat work and internal energy?
What is the relationship between heat work and internal energy? The relationship between the internal energy of a system and its heat and work exchange with the surroundings is: E = q + w (The form of work will be restricted to gaseous, PV-type for this discussion.) Interestingly, both q and w are not state […]
Why is it hard to find the ideal CO2 level If the light intensity?
How can water be used to generate electricity at home?
How can water be used to generate electricity at home? A new turbine uses running tap water to generate electricity at home. Vortical Tech LLC launched the first prototype of their turbine, which generates electricity whenever tap water is used. The hybrid Tesla turbine converts kinetic energy produced by the flow of water into electricity. […]
Why diffusion is faster in water?
Why diffusion is faster in water? This is because in hot water, the water molecules have more energy and are moving faster than the molecules of cold water. Because diffusion happens from high concentration to low concentration, the more molecules are moving, the more opportunities they have to mix together. What is the slowest diffusing […]
What happens if centrifuge is not balanced?
What happens if centrifuge is not balanced? Centrifuges, which operate at high speed, have great potential for injuring users if not operated properly. Unbalanced centrifuge rotors can result in injury or death. Sample container breakage can release aerosols that are harmful if inhaled. What is the principle of centrifuge? A centrifuge works by using the […]
What is the pH of calcium carbonate?
What is the pH of calcium carbonate? At pH values of less than about 6, mostly dissolved carbon dioxide and a small amount of carbonic acid exist in water. At pH values of between about 6.5 and 10, bicarbonate is dominant. At pH values greater than about 10.5, the carbonate ion dominates. What does CACO3 […]
What speed means?
What speed means? the rate at which something moves, is done, or acts. physics a scalar measure of the rate of movement of a body expressed either as the distance travelled divided by the time taken (average speed) or the rate of change of position with respect to time at a particular point (instantaneous speed). […]
How many protons and electrons are in oxygen?
How many protons and electrons are in oxygen? 8 Is the number of nucleons equal to the number of electrons? The atomic number gives the number of protons in the atom. The number of nucleons gives the total number of protons plus neutrons in the atom. Since an atom is electrically neutral, an atom has […]
