fragments or satellites, where the clusters form. We review the impact of multiple populations on different regions of the colour–magnitude diagram and underline the constraints related to the observed abundances of lithium, to the cluster dynamics, and to the frequency of binaries in stars of dif...
is a semiring (albeit one without an additive identity element), which is idempotent: for all . More generally, addition can be described in purely order-theoretic terms: for all . (It would therefore be natural to call a tropical semiring, although the precise axiomatization of this term...
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...
In chemistry, an orbital (region of space) can be defined as a 3D-description or mathematical function used to determine where an electron (negatively charged subatomic particle) is most likely to be found around an atom. The four types of orbitals can be identified...
This current work is not intended to give a deep expose on any one topic rather highlight some of the seminal works in topical areas and bind them together. Over the past 5 years there has been an increase in the interest in the use of ferroelectric materials as photocatalysts, or their ...
What is the total number of nodes in the c3 and c4 MOs of 1,3-butadiene? Verified step by step guidance 1 Step 1: Understand the concept of nodes. In molecular orbital (MO) theory, a node is a region where the probability of finding an electron ...
That is to say, a nonstandard order of infinity is an equivalence class of functions defined on elements of the ultrafliter. For instance, if is the natural numbers, then itself is an order of infinity, as is , , , , and so forth. But we exclude ; it will be important for us ...
What is the difference between them? Could their chemical formulas be represented differently? Chemical Bonds: Chemical bonds are the forces that hold the atoms together in a molecule: These forces are of various types. So, ...
Chemistry class (Photo Credit : Elegant Solution/Shutterstock) When you see a molecular diagram or read a molecular formula, it may not immediately be apparent whether you are seeing a molecule or a compound. In fact, you may not even know if there is a difference between these two designati...
What is the basis of the VSEPR model of molecular bonding? A) electron domains in the valence shell of an atom will arrange themselves so as to minimize repulsions B) hybrid orbitals will form as necessary to, as closely as possible, achieve spherical sym ...
