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 is the electric potential at the halfway point between the two charges?
What is the electric potential at the halfway point between the two charges? At the midpoint between the charges, the electric potential due to the charges is zero, but the electric field due to the charges at that same point is non-zero. At what point or points on the is the electric potential zero? PROBLEM […]
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 is not an example of mechanical wave?
What is not an example of mechanical wave? Light, sound, and waves in the ocean are common examples of waves. Sound and water waves are mechanical waves; meaning, they require a medium to travel through. However, light is not a mechanical wave; it can travel through a vacuum such as the empty parts of outer […]
Where are valence electrons located and why are they important?
Where are valence electrons located and why are they important? The electrons that occupy the outer most shell of an atom are called valence electrons. They are important because they determine how an atom will react. By writing an electron configuration, You’ll be able to see how many electrons occupy the highest energy level. Why […]
What should you not do with a pacemaker?
What should you not do with a pacemaker? What precautions should I take with my pacemaker or ICD? It is generally safe to go through airport or other security detectors. Avoid magnetic resonance imaging (MRI) machines or other large magnetic fields. Avoid diathermy. Turn off large motors, such as cars or boats, when working on […]
Is Proctorio always on?
Is Proctorio always on? Once I install Proctorio, is Proctorio always on? No, Proctorio only runs during an exam. Test Takers can tell when Proctorio is “on” because the Proctorio shield icon will turn green. Proctorio only records during an exam, and if the video/audio/screen recordings settings are enabled by the exam administrator. Can Proctorio […]
What do prokaryotes and eukaryotes have in common?
What do prokaryotes and eukaryotes have in common? Both prokaryotic and eukaryotic cells have structures in common. All cells have a plasma membrane, ribosomes, cytoplasm, and DNA. Ribosomes are the non-membrane bound organelles where proteins are made, a process called protein synthesis. Do prokaryotic and eukaryotic cells have Golgi bodies? Eukaryotic cells contain a membrane-bound […]

What is the difference between the shutter and the diaphragm?
What is the difference between the shutter and the diaphragm? is that diaphragm is (anatomy) in mammals, a sheet of muscle separating the thorax from the abdomen, contracted and relaxed in respiration to draw air into and expel air from the lungs; also called thoracic diaphragm while shutter is one who shuts or closes something.
