Did you know that DNA, the molecule that carries the genetic instructions for life, is negatively charged? The negative charge Read More » 1월 5, 2023 8 Pro Tips: How to spot a fake DNA Test Results Detecting fraudulent DNA results is important, as inaccurate test results can have...
An RBC contains hemoglobin, a molecule specially designed to hold oxygen and carry it to cells that need it. The primary function of red blood cells is to transport oxygen from the lungs to the cells of the body. RBCs contain a protein called hemoglobin that actually carries the oxygen. In...
Which periodic property is particularly important to nerve signal transmission? Why? How many codons would be possible if each consisted of four nucleotides? Would this be workable as an amino-acid code? Sulfur dioxide is a nonlinear molecule. How many vibrational modes will this compound have?
represent hydrogen atoms. In (b), a representation of a water molecule’s molecular formula is presented. The letter “H” symbolically refers to the hydrogen atom, the number “2” refers to the number of hydrogen atoms in the molecule, and the letter “O” symbolically refers to the oxyg...

those that respond to C-H bonds like the flame ionization detector (FID); those that respond to specific elements for example sulfur, nitrogen or phosphorus; and those that respond to specific properties of the molecule, like the ability to capture an ...
The type and number of hybrid orbitals depend on the number of valence electrons and the geometry of the molecule. For example, carbon can form four sp^3, three sp^2, or two sp hybrid orbitals depending on whether it is bonded to four, three, or two atoms, respectively. ...
Sometimes it is necessary to describe the whole molecule but not to draw every single atom and chemical bond in full.Organic molecules are often represented by skeletal formulae (i.e. only their skeletal structures) in cases of molecules beyond a certain size and complexity. Moderately advanced ...
To make a normal fat, you take three fatty acids and bond them together with glycerol to form a triglyceride, like this: Since this particular triglyceride happens to contain three molecules of stearic acid, it is also known as tristearin. This diagram shows one fat molecule. When you eat ...
Draw the Lewis structure of O2. How many pairs of bonding and non-bonding valence electrons are in this molecule? *WARNING: you only have one attempt for this quiz, please read the textbook before attempting to answer these questions* ...
