Is oxygen a donor or acceptor? Oxygen is an oxidizing agent (electron acceptor) and hydrogen is a reducing agent (electron donor). What are the best electron donors? When a really good donor meets a great acceptor, the chemical reaction releases a lot of energy. Oxygen (O2) is the best electron acceptor and is used in […]
What type of system is a hydraulic system?
What type of system is a hydraulic system? A hydraulic system is a drive technology where a fluid is used to move the energy from e.g. an electric motor to an actuator, such as a hydraulic cylinder. The fluid is theoretically uncompressible and the fluid path can be flexible in the same way as an […]
What should you not say to a lonely person?
What should you not say to a lonely person? 4 Things You Should Never Say To Someone Suffering From Loneliness “You just need to go out more and meet more people.” “You just need more confidence.” “You’ll stop being lonely when you meet your other half.” “You should join a meet-up group or do more […]
What is the basic source of magnetism?
What is the basic source of magnetism? The source of magnetism is the electric charges. The movement of the electric charge causes magnetism. Substances are made from tiny atoms. These atoms have protons, electrons and neutrons. Where is magnetism found? A very common source of magnetic field found in nature is a dipole, with a […]

Is methane a good fuel source?
Is methane a good fuel source? Methane provides a great environmental benefit, producing more heat and light energy by mass than other hydrocarbon, or fossil fuel, including coal and gasoline refined from oil, while producing significantly less carbon dioxide and other pollutants that contribute to smog and unhealthy air. Is methane safe to breathe? Inhalation: […]
Why do cheetahs have very little genetic variation?
Why do cheetahs have very little genetic variation? Even though the number of cheetahs grew to as many as 100,000 during the 19th century, their genetic variability remained low due to the extreme bottleneck event that took place thousands of years previously. What are the two types of variation? There are two forms of variation: […]
What is the relationship between molecular motion and pressure?
What is the relationship between molecular motion and pressure? The greater the molecular motion, the greater the pressure the molecules exert. What is heat in terms of molecular motion? Molecules are in constant motion and so they possess kinetic energy. Molecules at a higher temperature have more kinetic energy i.e. they move faster. Heat is […]
What gases are least ideal?
What gases are least ideal? 1 Answer. Sulfur dioxide should be the least volatile, have the greatest intermolecular interaction, and thus its behaviour is LEAST like the ideal. What is the difference between ideal gas and non ideal gas? Real gas and Ideal gas. As the particle size of an ideal gas is extremely small […]
What does emission mean?
What does emission mean? An emission is something that has been emitted—released or discharged. In general, emissions consist of things like gas, liquid, heat, sound, light, and radiation. This exhaust is just one form of carbon emissions—greenhouse gases from various sources that are known to contribute to global warming and climate change. What is emissions […]
