Can tsunamis be stopped? Tsunamis could be stopped before they hit the coastline, a Welsh mathematician has proposed in a study of deep-ocean sound waves. Dr Usama Kadri, from Cardiff University’s School of Mathematics, has suggested that firing deep-ocean sound waves at an oncoming tsunami could save lives and reduce on-shore damage. What disaster will […]
What is the significance of quantum number?
What is the significance of quantum number? Quantum numbers are important because they can be used to determine the electron configuration of an atom and the probable location of the atom’s electrons. Quantum numbers are also used to understand other characteristics of atoms, such as ionization energy and the atomic radius. Which of the following […]
What color is lowest in energy?
What color is lowest in energy? Red What are the forbidden colors? Red-green and yellow-blue are the so-called “forbidden colors.” Composed of pairs of hues whose light frequencies automatically cancel each other out in the human eye, they’re supposed to be impossible to see simultaneously. The limitation results from the way we perceive color in […]
Can atoms be broken down into smaller pieces?
Can atoms be broken down into smaller pieces? Under normal circumstances an atom can be broken down into any smaller particles, but we humans, have devised ways to break the atom apart. An atom itself is made up of three tiny kinds of particles called subatomic particles: protons, neutrons, and electrons. How many atoms are […]
Does anti glare coating wear off?
Does anti glare coating wear off? The average AR coating should last about 2 years in my experience under moderate temperature and cleaning abuse,but if you are exposing your glasses to more extremes they could break down within a few months. Can I put anti glare on my glasses myself? Can I Add Anti-Reflective Coating […]
What coefficient is placed in front of O2?
What coefficient is placed in front of O2? The coefficient for O2 is 7. When C2H4 reacts with oxygen One product is water? When C2H4 reacts with oxygen, one product is water. Pentane (C5H12) reacts with oxygen (O2) to form carbon dioxide (CO2) and water (H2O) according to the following reaction. Answer the following question(s) […]
What is a join between atoms called?
What is a join between atoms called? When two electrons are shared between two neighbouring atoms, they are said to be joined by a covalent bond. When covalent bonds form between atoms, the resulting entity is called a molecule with a fixed characteristic geometry. What is the basic unit of matter? In turn, the atom […]

What are 3 uses of beryllium?
What are 3 uses of beryllium? Beryllium is alloyed with copper or nickel to make springs, gyroscopes, electrical contacts, spot-welding electrodes and non-sparking tools, according to the Royal Society of Chemistry. Other beryllium alloys are used in high-speed aircrafts and missiles, as well as spacecraft and communication satellites. Why is beryllium so expensive? Beryllium is […]
Is 1 degree Celsius cold or hot?
Is 1 degree Celsius cold or hot? In the Celsius scale there are 100 degrees between the freezing point and the boiling point of water compared to 180 degrees in the Fahrenheit scale. This means that 1 °C = 1.8 °F (check the section about temperature differences below). What is the coldest Fahrenheit temperature? The […]
