For a given element, the mass (in grams) of one mole is given by its mass number on the periodic table; the "molar mass" of a molecule is the sum of the molar masses of the elements in the molecule in the correc
Master How To Determine Solubility with free video lessons, step-by-step explanations, practice problems, examples, and FAQs. Learn from expert tutors and get exam-ready!
Titration is used to determine the concentration of an unknown substance via the molar relationship expressed through the chemical reaction equation. Using these relationships, the pH value can be determined by calculating the concentration of hydrogen i
How do intermolecular forces and kinetic energy interact to determine at what point a liquid will boil?Intermolecular Forces:Intermolecular forces are attractions between neighboring molecules that help determine the melting and boiling points of substances. The three...
Explain how you could use the melting point to determine the purity of a solid sample. What effect does the sample size of the melting point have on the melting point? Why do impure molecule have lower melting points? Explain the simple criteria of purity and melting point. ...
Although not as versatile as carbon, silicon can also form up to four bonds with other atoms and has been proposed as a basis for molecules of alien life (silicon-carbon hybrid molecules have also been proposed). It is likely that alien life forms would have some type of complex molecule ...
, by the boiling point of the solvent) and is often not sufficient to overcome the energy barrier. For this reason, colloidal dispersions are commonly destabilized by lowering the energy barrier. In charge-stabilized dispersions, this can be done by modulation of the Debye length and thus the...
Here is a chart that can be helpful to determine what stage of iron deficiency someone is in: If you have a practitioner who is willing to work with you, that practitioner can order these tests for you. If you don’t have one, you can self-order theferritin test,CBC, andiron/TIBC ...
Bottom Line: Use Relative Electronegativities, Not Formal Charges, To Determine Electron Densities Notes 1. How Do We Tell Where The Electrons Are? First, Draw The Lewis Structure OK. Let’s start with the first question: how do we tell where the electrons are in a molecule?
