Is o2 an ionic compound? An oxygen molecule (O2) is a good example of a molecule with a covalent bond. Ionic bonds occur when electrons are donated from one atom to another. Table salt (NaCl) is a common example of a compound with an ionic bond. You may also learn about a third type of […]

What proves a permanent magnet?
What proves a permanent magnet? A high magnetic ordering temperature (called the “Curie temperature” or Tc), below which the material is spontaneously magnetic. A large remanent magnetic flux (called “remanence” or Br) maintained in the absence of an external magnetic field. A strong resistance to demagnetization (called “coercivity” or Hc) What is the strength of […]
How do you trick a motion sensor?
How do you trick a motion sensor? Most motion detectors, even newer ones, use infrared to detect significant changes in the surrounding room’s temperature, Porter said. Normally, walking around in a room would set off these sensors, but using something as simple as a piece of styrofoam to shield your body can trick them, he […]
Do Coral reefs produce oxygen?
Do Coral reefs produce oxygen? While coral reefs only cover 0.0025 percent of the oceanic floor, they generate half of Earth’s oxygen and absorb nearly one-third of the carbon dioxide generated from burning fossil fuels. How do coral reefs benefit from herbivorous fish? Another functional group of herbivorous fishes are the ‘grazers’. Much like a […]
What happens if atmospheric pressure is too high?
What happens if atmospheric pressure is too high? As the pressure decreases, the amount of oxygen available to breathe also decreases. At very high altitudes, atmospheric pressure and available oxygen get so low that people can become sick and even die. What is considered high pressure weather? A barometer reading of 30 inches (Hg) is […]
What are reactants examples?
What are reactants examples? Reactants are substances initially present in a chemical reaction that are consumed during the reaction to make products. Some chemical reactions go to completion, resulting in all of the reactants becoming products. These reactions are said to be irreversible. For example, burning methane in oxygen is irreversible. What are the 7 […]
What is reverse causality example?
What is reverse causality example? According to Katz (2006), identifying reverse causality is sometimes a matter of “common sense.” For example, a study might find that brown spots on the skin and sunbathing are linked. While it is plausible that sunbathing can cause brown skin spots, it’s highly unlikely that the brown spots cause sunbathing. […]
