How are natural elements formed? Atoms that share electrons have what type of bonds? How are atoms and elements related? How is water a molecule and a compound? In what ways are hydrogen bonds and ionic bonds similar? When two hydrogen atoms chemically bond to one oxygen atom, what do the...
Water vapor is the most abundant greenhouse gas, but it is more often than not aresult of climate changesrather than man-made emissions. Water or moisture on the Earth's surface absorbs heat from the sun and the surroundings. When enough heat has been absorbed, some of the liquid's molecu...
How were the heavier chemical elements formed? How are chemical elements identified? What is formed when elements of matter are chemically combined? How are chemical elements named? How are chemical elements different from chemical compounds? How do elements combine to form compounds? How are differe...
Diamonds have a higher index of refraction than water, which is to say that those sparkly, costly light traps slow down light to a greater degree. Lenses, like those in a telescope or in a pair of glasses, take advantage of refraction. A lens is a piece of glass or other transparent ...
Soil aggregate stability further increases the capacity of soils to store C, as SOM formed in aggregates or sorbed by organic-mineral interfaces is physically protected due to its physical inaccessibility to extracellular enzymes and/or microclimatic conditions, referred to as an “entombing effect”...
NCERT solutions for CBSE and other state boards is a key requirement for students. Doubtnut helps with homework, doubts and solutions to all the questions. It has helped students get under AIR 100 in NEET & IIT JEE. Get PDF and video solutions of IIT-JEE Mains & Advanced previous year pap...
But what exactly is light? We catch glimpses of its nature when a sunbeam angles through a dust-filled room, when a rainbow appears after a storm or when a drinking straw in a glass of water looks disjointed. These glimpses, however, only lead to more questions. Does light travel as a...
RBCs contain an enzyme called carbonic anhydrase which helps the reaction of carbon dioxide (CO2) and water (H2O) to occur 5,000 times faster. Carbonic acid is formed, which then separates into hydrogen ions and bicarbonate ions: Carbonic Anhydrase CO2 + H2O ===> H2CO3 + H+ + HCO3- ...
It is reported that adding sucrose to a KOH solution of pH 13 completely blocks the dissolution; contrary to when the sucrose is added to pure water, in which case the dissolution does take place. This experiment was performed at high dilution, so that the pH can be considered constant ...
How is iron ore formed? How is salt formed? How does borax soften water? Explain the process of fractional distillation. How does sodium bicarbonate affect potassium? How are nitrates produced? How does a baking soda volcano work? Why is CO2 produced in fermentation?
