what mechanism occurs in raynaud phenomenon that classifies it as a type iii hypersensitivity reaction?
The Raynaud phenomenon has a type iii hypersensitivity reaction mechanism in which immune complexes are deposited in tissues after antibodies bind to soluble antigens and are released into bodily fluids.
What Raynaud syndrome mechanism is categorized as a type iii hypersensitivity reaction?Immune complexes, which are lattices of antibodies and antigen, are formed when antibodies react to soluble antigen. Immune complexes (IgG or IgM), which are typically cleared by macrophages in the spleen or liver, become too numerous to be handled by these protective mechanisms.

true or false: before and after a chemical or physical change, the difference in potential bond energy between the reactants and products is known as the intermolecular force strength.
True; before and after a chemical or physical change, the difference in potential bond energy between the reactants and products is known as the intermolecular force strength.
The force that mediates interactions between molecules is known as an intermolecular force (IMF) or secondary force. It includes electromagnetic forces of attraction or repulsion that act between atoms and other types of nearby particles, such as atoms or ions. The forces that hold a molecule together, or intramolecular forces, are stronger than intermolecular forces. For instance, the covalent bond, which involves sharing electron pairs between atoms, is significantly more powerful than the forces that exist between nearby molecules. Both types of forces play a crucial role in the force fields that are routinely employed in molecular mechanics.
The study of intermolecular forces begins with macroscopic measurements that show such forces exist and function at the molecular level..

how many coulombs of positive charge are contained in the atomic nuclei of this gas?
The total positive charge in the nucleus of any gas is the total number of protons times the total charge contained by one proton. The total number of protons depends on the type of gas, for example, hydrogen, oxygen, chlorine, etc. Each gas has a different number of protons in its nuclei.
To calculate the total positive charge in the atomic nuclei of any gas, find the total number of atoms in the gas. It can be calculated by multiplying Avogadro’s Number with the total amount of gas in moles. If the gas is available in molecules like , then it needs to be multiplied by 2 to calculate the correct number of atoms in the gas. The total number of protons needs to be calculated, which can be done by multiplying the atomic number of gas with the total number of atoms calculated before. Now we can calculate the charge by multiplying the charge on one proton by the total number of protons. A body that has more protons than electrons is said to have a positive charge.
