An element is a pure substance made up of atoms with the same atomic number. A compound is a pure substance made up of two or more elements. The smallest unit of a compound is a molecule. A mixture, on the other hand, is a substance formed ...
A(n) ___ removes hydrogen ions and a(n) ___ releases hydrogen ions. a) compound, element b) acid, base c) base, acid d) molecule, acid e) element, compound The combinations of carbon dioxide and water form the acidic product called ___. What is...
Carbon DioxideorCO2is an odorless and colorless gas that is vital for life as we know it. It is a naturally occurring compound composed of one carbon atom covalently double-bonded (sharing electron pairs) to two oxygen atoms. It is also a greenhouse gas. CO2exists in our atmosphere as a ...
1. Identify the Nature of Carbon Dioxide: - Carbon dioxide (CO₂) is a chemical compound composed of one carbon atom and two oxygen atoms. It is a linear molecule with a symmetrical arrangement. Hint: Look at the molecular structure of CO₂ to determine its polarity. 2. Determine Pol...
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...
Recently, mesoporous silica (MS) has been used as a material able to maintain amorphous state of active compounds and therefore, enhance the oral bioavailability of BCSII drugs. Among impregnation methods of MS, techniques using supercritical carbon dioxide (Sc-CO2) are promising tools. Solubility ...
TEA is both a tertiary amine and a triol. A triol is a molecule with three alcohol groups. Approximately 150,000 tonnes were produced in 1999. It is a colourless compound although samples may appear yellow because of impurities. Reports indicate that in India itself, as many as six ...
Atoms and/or molecules in two or more elements can join together to form a compound. This compound, which is the basis of matter, may not resemble any of the original ingredients. For example, sodium and chlorine, two highly poisonous elements that are unstable at room temperatures, combine ...
It seems counterintuitive that carbon dioxide, the compound that's reduced in photosynthesis, gains electrons. This electron transfer is called reduction because the addition of negatively charged electrons reduces the overall charge of the molecule; that is, it makes the molecule less positive and mo...
a soccer-ball-shaped sphere made of 60 carbon atoms. The research team named their discovery the buckminsterfullerene after an architect who designed geodesic domes. The molecule is now more commonly known as the "buckyball." The researchers who discovered it won aNobel Prizein Chemistry in 1996...
