The term chemical bond refers to the attractive force that holds the constituent atoms or ions of a molecular species together. Bonding is, in fact, nature's way of lowering the energy of the system to attain stability.Answer and Explanation: ...
Answer to: What is the definition for the term "formula unit"? Explain why this is needed when discussing the formula for an ionic compound. By...

The models are tested by mutagenesis using an MHC and a TCR mutated to alter conformation changes. The extensive comparisons between theory and experiment provide model validation and testable hypothesis regarding specific conformational changes that control bond profiles, thereby suggesting structural ...
Cold-adapted enzymes from psychrophilic species show the general characteristics of being more heat labile, and having a different balance between enthalpic and entropic contributions to free energy barrier of the catalyzed reaction compared to mesophili
which yields ΔH‡ = 14.8 andTΔS‡ = −8.9 kcal mol−1at 15 °C (Fig.3b). This shows that the two enzymes are able to reduce both ΔH‡and −TΔS‡, but that the faster psychrophilic enzyme has a larger effect on the enthalpy term. Hence, the tran...
Explain what is meant by the term "hybridization" in molecular orbital theory and show how the concept can be used to explain the structure and bonding in ethane C2H6, ethene C2H4, and ethyne C2H2. Use valence bond theory to describe which atomic orbitals overlap...
How do hydrogen atoms make a covalent bond? In chemical compounds, what is meant by the term the valency and the bonding requirements of the individual atoms? How do ions form ionic bonds? How are atoms held together in metallic bonding? How to determine hybridization from Lewis structure What...
In Biology, why is the hydronium ion or H30 have a positive charge? Explain the differences between single, double, and triple covalent bonds. How do voltage channels affect gated channels? Explain in simple term covalent bonds and properties. Explain all the element bonds. Mambalgins are inhib...
Also, explain why the term "ion pairing" is sometimes used to describe this phenomenon. Describe through an illustration what the effect of changing the ionic strength of a solution has on the solubility of a salt, for example, of CaCO3. How does MO theory explain bond length...
